Two things I've noticed as a myopic person. The intensity of bright colors does not diminish although details such as lines, shapes, and patterns either merge or cannot be seen. More important, the blurring shown in this otherwise fantastic video does not take perspective into account. By this, I mean that distant objects are blurrier whereas nearer objects are not as blurred.
true i had -11,60 in both (i'm fucking blind T_T) and the nearest thing i can see as similar is whenever you play a game with bad pc and things near you loaded but things in middle range are half loaded and far away didn't load yet xD

Yes, this happens even with -2, walking on the street uncorrected, you won't be able to see anyones facial features until they are within 5 meters pretty much. My vision has gradually worsened the past few years, from -1.something, to -3~ish (Haven't had it tested in a while), and slowly faces just disappear. People on the street are just blobs of color, faces are a blur. Uncorrected I recognize people by other tells, and sometimes I can only recognize them when they are within 10 meters. Even with this video, I can't imagine what it is like to have -10 in reality. I expect the whole world to just be a haze, almost like a kaleidoscope of light and color, but no definable features.
@luka188 I’m -9.5 in one eye and -10.5 in the other, and that’s exactly what it’s like. Just random soft color areas blurring into each other everywhere. It’s not necessarily unpleasant. It can be kind of relaxing, actually. Like I kind of feel less self conscious and more at ease, as if no one else can see me either, haha. But it’s crazy to think of how disabling it would have been for most of human history, before we had glasses.
My prescription -13. 🙁 It’s so hard to express to family/friends how severe my myopia is. So many videos only show up to -6. Thank you for showing -10. This is such a great communication tool. If you can, it would be helpful to show even more severe cases. Thank you! I appreciate you making these videos.
@@bibliophilelinda Yeah… he already had -20 myopia when he was at school. Now he wears -38 left eye and -37,5 right eye. Thankfully he said his eyesight haven’t gotten worse in the last few years 👍
I've had a driver's license for 45 years and been a high myope longer than that. Your video finally explained why I never like to wear sunglasses while driving, much to the dismay of my mild-myopic family members. I need all the vision I can muster while driving, so I prefer to wear my distance-only prescription (not progressives) with large, clear, untinted lenses.
3:47 As a 15 years teenager seeing this and having a -1 Myopia. This is truly scary. I have worked to stop my myopia progression and trying to regain my vision. Even at a -1 Myopia which is considered Mild and not very bad or extreme, this comparison at 3:47 20/20 to 20/40 (I think 20/40 is -1) is terrifying! And thw worse the vision gets, ofc it's harder and depressing... I wish it to no one and may God let the people see the best... Amen.
This is garbage.. im -8 and -7.5 and this is nowhere close of reality.. those simulators are way off of what reality looks like! I see WAY WAY better that what you’ve seen when i sont have my glasses. Dont worry youll be fine
20/40 is not quite -1 im pretty sure; probably closer to -0.75. I used to have 20/40 and 20/70 two years ago, but its gotten much worse. I now have -1.75 and. -1.50 which is closer to 20/100 :(
@@Melanochrysums I had -0.75 right (20/40) and -1.25 left (20/70) that was 3 years ago when I was 9. Now it’s -3 (around 20/300) in my right and -5 (around 20/500) in my left.
This was great, especially the indoor outdoor differences and the book distances. I remember taking a picture of a building once and being astonished that the text on its roof was legible on the photo but not to me. That's when I knew I needed glasses. Would be nice to see this with human faces as the subject. I'm sure you've heard the "you look prettier without my glasses on too" joke/comeback, but what is it actually like? Do human faces become unrecognizable, at what distance? I'm sure there's also embarassing stories to tell of people not recognizing their friends because they weren't wearing glasses.
Yes faces would be interesting to see, I have -6 vision and the few times I’ve been in public without glasses or contacts I felt completely lost not being able to tell who anyone was!
I don't have myopia. I have presbyopia and I can see faces better without glasses. I can't see computer screens without my glasses, so webcam calls get weird because I am looking at faces on a computer screen.
I have a mild case of just -0.75 myopia and at night I can't recognize faces at all. I have to get into talking distance in order to see faces clearly. All people around me have blank slates as faces. It sucks.
I recognise people by their movements, walk, posture, style, voice. When I’m on a computer, I take off my glasses, (stupid multifocals, have to tilt my head back to use the bottom of the lenses to see the screen, hurt my neck). I also take them off when it rains and I have to wipe them. If I’m in public with glasses off, I will not be sure if it’s the person I think it is.
Great video! When i got my eyeglasses back when i was a teenager, it read -4.75. As i wore them all throughout my life, my latest grade is now at -3.50 and -3.75 in each eye. These new glasses were made less than a year ago. I'm turning 40 this year, and i noticed that whenever i read words closer to my eyes, they tend to blur now compared before, so i have to adjust and move farther whatever I'm reading. I think it's because I'm entering the stage where my eyes are starting to get older (they say it starts at 40) so I'm reminded everyday that not only do i have myopia, but would also have to contend now with early onset of presbyopia. 😢
Holding a book mere centimeters away in order to read it is certainly a familiar feeling (-10). I actually find it quite advantageous when working with very small objects to be able to take off my glasses and focus in right up close without the need for a magnifying glass. I imagine this would not be possible for people with a more distant depth of field. An interesting note about having such a close and narrow depth of field (and binocular vision): With uncorrected vision, I can no longer focus on an object with both eyes at once, because once something is within my far point, the separate images from each eye are too different to be reconciled. Whenever looking at my phone in bed, I always have one eye closed, otherwise it's impossible to see. Sort of like trying to focus on anything while cross-eyed. This is something that the single-lensed camera cannot replicate. The shot of the church shows very well how the world turns into blobs of colors for myopes. We can still see shapes, especially when there is strong contrast, but details are all but absent. Love the Jinx mural!
One of the things I rediscovered after starting using glasses were the reflections. I didn't notice them before. Especially cars became very reflective. I think it could be a great material if you film naturaly reflective surfaces with different grades of myopia.
I literally just asked a question on another of your videos that things seem blurry at night in the distance but not during the day. Then went through your videos (after subscribing of course) and found this which basically answered my question! Definitely going to ask about this next time I get my eyes checked
My vision is about -7.5. There are a couple things I have noticed. I've started wearing my glasses for longer periods of the day rather than my contact lenses to try to give my eyes more of a break. As an experiment, when I take a walk I take off my glasses and walk for a while to see the world uncorrected. I've noticed when the sun is very bright, there are moments I can almost see the texture of the pavement. On a cloudy day not so much. Another observation is more of a question. My eyes drip like crazy when I'm wearing my glasses. Why is that?
@@badrikokaia4603 There is a reason why. When your eyes are exposed to bight light (sunlight), your pupils contract and become smaller. Less unfocussed light enters your eye and blurry vision is less noticeable. In low light your pupils dilate to let in more light. More unfocussed light enters your eye and the blurry vision is worse.
Interesting video. I have had myopia since birth, prescription currently -13. My far point of focus is 8.8 cms and near point 6.9 cms, so a very narrow depth of field. With spectacles my vision is 20/20 on the right and 20/15 on the left, near point 20 cms, far point right to the horizon. Incidentally, with extreme myopia, the image doesn't only get more blurred it also breaks up and fragments. The best example is looking down a street at night without specs and seeing how the small street light bulbs in the distance become huge circles of dots, almost like a large dandelion head which has gone to seed! The camera does not mimic this.
This is great! You have a really great understanding of the optics issues and have an inspired way of illustrating them. And what's more, you are obviously very interested in your field. Love it.
This is great explaination, I want to add up more information is that the blur is not the only thing but our eye trying to adjust itself cause huge irritation, annoying, eye strain and the tired of the eye which make the feeling of putting out the glass much worse than watch this clip
Great topic and video Antonio. Your presentation is admirable - but the camera lens blur simulation does not quite describe the effect - especially in lower light/indoor settings. I would say that blur is not as bad as you show here in interior lighting scenes (maybe due to how rods and cones work in different lighting conditions?). Also I would say most folks who have myopia also have slight astigmatism as well, which does not offer the same even “blue filter” when blurring a spherical lens evenly using something like Gaussian blur. I find that while an image at -4 is blurry, the average myope (without bad astigmatism) can still resolve certain elements of these scenes with perceivably less blur, while having the macro scene still blurry, if that makes any sense.
Hi Antonio the Optometrist! The reason Adelaide is called the city of churches is because Adelaide was the first city in Australia, maybe the world, where it was legal to practice your own religion, regardless of the denomination! Thanks for your video!
Former high myope -10 with -3 astigmatism. I had a lens replacement in both eyes for cataracts four years ago. I’d been wearing custom gp contacts, monovision, but was becoming increasingly intolerant of them and wearing glasses wasn’t ideal for driving due to edge distortion. I had night blindness. The lens replacement changed my life! I opted for monovision so I wear readers for close view in low light, but otherwise I need no glasses for distance, day or night. I almost cried when seeing your examples of what my vision was before. People really have no idea how debilitating high myopia is. I am so grateful that the lens replacement healed me. It was a miracle.
To add a bit more about the night blindness, I am not sure if this was due to the monovision with the gp contacts, or residual astigmatism that was uncorrectable, but I had no depth of field ability when judging oncoming headlights. There were also halos. This made night driving extremely dangerous, not only for me personally, but for all other people on the road driving with people who have this affliction and still try to drive at night anyway.
@@nancyeaton731 People with high myopia can find it more difficult to see in low light/dark. I have a friend with high myopia and he is not allowed to drive at night.
hey im - 11 high myopia and my doctor suggested me clear lens exchange, im 32 yo, would i go or not im worrying it will not be successful coz of high grade and still wearing eyeglass or retinal detachment or maybe some laser prk after surgery.
@@Chanbro4yes… it absolutely does. And my current issue is that my glasses are so heavy that they’re giving me pressure sores on my bridge. I’ve gone into the clinic almost every other week since November without any luck in getting that to stop
Very helpful! I know I have astigmatism and myopya since then because of the Checkups I had. But I haven't had my new eyeglass as of now, it gotten worse I know. Hoping to get a new one I miss the clear vision I had before huhuuu Thanks again for this video of yours! Everyone who don't understand what we say will believe if they see this coz they tend to laugh or don't believe lol.
My right eye had a problem with the retina separating from the back of the eye. I went in emergency surgery and they were able to reattach it to the back of my eyeball. The surgery was a success as far as restoring my vision but I developed a caterac (as 90% of patients with this surgery do) and had to have a lens replaced. I can still see with this eye but my focus at the center of my eye is fuzzy. I can see a person in front of me and make out most of the details but not much of the fine details. Now my left eye is what my right eye was before the need for surgery. I can make out every line printed on a $100 dollar bill as long as it is within 6 inches. I just can't read the dashboard of a car without my glasses. My vision I think is -8.50. BUT the iris of my right eye is always comparatively dialated. This is why it appears that on bright sunny days I seem to be winking at people. In reality, I close my right eye because the brightness is painful and most everything I see is washed out.
This was pretty interesting. I'm very close to the -10 shown in the video (-9 in my right eye, -8.75 in my left), along with a bit of astigmatism (-0.5 at 95 degrees in my right eye, -1.25 at 25 degrees in my left). What I find really fascinating though is that my far point is closer than what you measured for someone at -10 - mine is 8 centimetres (basically the length of my index finger). It makes getting my photo taken for my ID particularly maddening because without my glasses on, I can't see where the camera's lens is and therefore have no idea if I'm actually looking at it 😅
I'm close to blind in left eye I have -7,00 with -9.00 astigmatism at 88 degree. I dont have any close or far focus points i can see best from 5 cm away if i take something more closer or further it gets more blurry.even from 5 cm its still little bit blurry. But my right eye is close to normal vision I only have -3.00 astigmatism at 117 degree my vision is perfect at daytime but gets liitle bit blurry at night. Im 15 years old and i wish that my left eye stopped progressing more. 😢 Also i don't wear glasses
Thank you for this and the work you put into it. Most of my family are at -4 or -5 but I’m at -10.5 and it’s very hard to explain that without glasses I can’t even navigate the house. I’ll send this video.
I have hyperopia, but I’ve always been confused when people say that individuals with hyperopia can see distant objects okay but have trouble with close up objects. My prescription is +8.5 in both eyes. Without corrective lenses, my distance vision is similar to the -10 you simulated, but instead of getting better as you get closer to the object, my up close vision it is equally as bad as my distance vision, so moving closer or further has no effect on what I can see.
Hi Antonio, love your videos! Could you do a video on whether or not constantly upping your glasses prescription makes your eyes accumulate to worse vision. My friend saw a study which apparently said there were links, but I don't know how true or not this is? or could you do a video on why eyesight degrades faster as a child/teenager and tends to stabilise as an adult?
Mine was -3, but because I’m a generation X I visited the opthamologist that my dad happened to be seeing(so no formal examination) and after getting my pupil response said there is nothing wrong with my eyesight. This carried on through middle, into high school.
I have oblique astigmatism and myopia,could you by any chance do a video like this one and the astigmatism one combined? I’m finding this really interesting. Just found your channel and I have never been so curious about my vision as I am now haha, like I have been wearing glasses since I was 5 or so, so I never really gave it much of a second thought till maybe a year ago, and now your videos give me even more curiosity. I use to wear an eye patch when I was a kid, still don’t know if that helped? That could also be an interesting topic to discuss, I hated wearing that thing as people looked at me funny and said things. I drew suns and moons on those eye patches, I used to stick them on the door, I remember my door being full of drawn eyepatches
@@mydogeatspuke they almost look in the same direction, one of them is slightly off (not really noticeable), but if Im really tired or I get nervous it's more easy for it to be noticeable I guess (without glasses I mean, with glasses I can't even cross my eyes , which I also find kind of weird) I think it's because Im not focusing so much on making it work, I relax my eyes if that makes sense. Also if I try to focus on using my left eye which is the lazy one I can make it completely straight but I can't see anything when I do this. Btw thanks for your quick response, it really does help me out!
@@meirienda that all sounds normal to me, including not being able to see if you force your lazy eye! Your brain automatically blocks the vision so you don't see double as it's corrected to see and work with your other eye at a specific position. It's quite clever how they correct it tbh!
@@mydogeatspuke wow, I didn't know that was because of the correction they made, thanks, this conversation has helped me understand a bit better!! Hope u have a nice day
I hate cloudy days with pure white sky. That punishes me a lot and going outside feels impossible since my eyes can't take too much light reflections from many angles
I have to disagree with the examples shown though, the indoor examples were way too blurry in comparison to how I see with the same diopter like -2 aint that blurry and -2 outdoors also looks to sharp
Hey Antonio. Thanks for your work. I've noticed by myself that blue led-signs, for example at shops, are way harder to read for me than other colors. Don't know the reason or if this effect could explained in an video. Greetings.
I have myopia at around -4.00, most of it probably results from me as a child thinking "I wonder what it's like to stare at the sun" and then actually doing it
One thing though, I actually enjoy myopia sometimes. I know this sounds like the punchline to a joke, but I find things like festive lights look better, or light reflected off water or whatever. Bokeh, but in real life, just walking around. I kind of wonder if anyone with astigmatism likes the look of lights at night.
Good for you. I have myopia and astigmatism and can't stand bright lights. The ones in shopping malls and neons inside offices are unbearable. Before wearing glasses, I avoided going out at night for the same reasons. My corrective lenses are photochromic, and wearing them is really a game changer.
But what exactly is your prescription all around for indoor and outdoor objects? I know glasses and contact lenses the diopter numbers are different, but for some reason I see better with lenses than glasses.
I strongly believe that the -1.00 and -2.00D images are quite inaccurate... With a -1.00 in my left eye without correction I see what you are showing as -4.00 or -5.00D.
Could you explain why suddenly I need readers? Also, why until now, my vision with contacts has be great but since needing readers it sucks. My Rx hasn’t changed either -2.5
I have myopia around -2 or slightly worse, probably from using the computer when I was young. I've managed to not break my glasses for over 10 years, wearing them sparingly only when needed. I've not been to an eye specialist, do I can't say my exact number. But I don't "suffer" from my near sightedness. I don't have a house anymore and don't need to work in the garden. I don't attend school and therefore don't get laughed at for my glasses. It would be far more troublesome if I couldn't see up close. Even work outdoors needs precision. An optometrist prescribed me a compromise glasses around -1.75. When I first put my glasses on, I loudly exclaimed like a fool in the optometrists office. I wear glasses when walking outside in the city and going shopping to search products on shelves, and avoid attracting security. I don't need perfect sharpness read text or distinguish a red light. The title of the book would be readable at some distance to the camera. There is still a range of focusing ability unlike your camera. I don't get how you derive meters from the diopters, which are a correction on top of the range that the eye has.
What has been said about the apperture size sounds reasonable and is probably true. I can't see the effect, because I see better with good light anyway, and there are other factors like if I take off my glasses I see very poorly initially. I can't read with distance glasses on at night, so I have to look past them. A weird feeling.
One of my eyes is short sighted the other longsighted, plus other issues. My optician was adjusting my glasses and told me to pick them up in an hour. So I walked down town New Plymouth, New Zealand this is, well my eyes did not cope well at all, that hour. But I found it fascinating all the same. Picked up my glasses and home to have headache meds. I laugh about it now.
Don't know if it's due to the screen effect or what, but I have a hard time resonating with the comparisons. I am now trying on -3.00 and -3.50 lenses as I am preparing for Lasik surgery. I also have medium astigmatism on my right eye. No way my vision without lenses or glasses is as bad as shown in the video, both outdoor and indoor. At daytime I can - with some effort - read license plates of cars parked across the street from my window (20m away) with no correction. And with -3.00 and -3.50 lenses my vision does not seem to be hypercorrected, actually it feels like I am still missing 0.25/0.50 per eye. Am I mixing measures up or how can this make sense?
I remember, once I left my rx glasses in the locker room for swim lessons. I felt so uncomfortable walking around because it was so blurry without my glasses. I ended up ordering some rx goggles.
I wish you'd have put examples with people/people's faces. I can navigate, with difficulty, being in a known street/area without glasses, but it is unbearable to interact with people without putting my glasses on - without seeing faces, I cannot tell who is talking in a group; it feels awful.
I think this wallart is undermined, you can`t see face lines with -5 and gym scene is exaggarated, you don`t have complete bokeh with - 5. The main thing what is going lost is smaller details like letters and face lines
Im myopic and astigmatic both in the -5.0 range in both eyes. Im in my mid 40's and so am starting to struggle with presbyopia. I guess its multifocal time but as an optical mechanic (have been out of the job for 20 years) i know im going to struggle with adapting. Not looking forward to it.
I'm short sighted with astigmatism too, but have also needed reading glasses since I was 28. I'd like to try varifocals but anything of a decent quality for driving would cost a small fortune. The total loss of peripheral clarity is what concerns me most, and of course the fact that they can never get my prescription right so I always have a headache and squinting. I'd rather not make it worse than it needs to be!
@@mydogeatspukeBro, why would you need reading glasses when you have myopia. Myopia means that you can see clearly in front of you, but not in the distance. People who are myopic with presbyopia can simply take their glasses off to see up close.
@@R3cce why would you need glasses at all if you're incapable of reading to begin with...? I said ALSO. In addition to my short sightedness I also have early onset presbyopia. I need distance AND reading glasses. And no, I can't just take off my distance glasses to see up close, and not only because of my astigmatism. If it was that simple, there would be no need for graduated lenses. Stop being silly.
@@R3ccelike what the op said - our eyes start getting older by the time we reach 40. This is currently happening to me now. I'm turning 40 this year, and have been myopic since I was a kid. Now I have to move objects/books/etc farther away because what used to be clear when I set them closer to my eyes are now blurred as well. That's why multifocal prescription glasses exists. To the OP, I feel the pain. 😢
Great video! I'm not sure what my actual prescription is, but pretty sure it's -7 in my left and -3 in my right. I have a question: can you explain why when I look in the mirror without glasses on, everything in the background is still blurry? It doesn't make sense to me because the mirror is not that far away so it shouldn't be blurry.
It's because the image of the background is at same distance behind the mirror even though u are closer Ie let say a clock behind u is at a distance 10 feet so when u see the mirror from a feet the image is actually 11 feet away from u That's why it's blurrier
I dunno if it was because I was born with it or what but I don't agree with what is shown on the video. My sight used to be somewhere around -10 to -12 from when I got my first glasses until maybe ten or so years ago. With those numbers there wasn't really any difference anymore if the chosen lens was -10 or -12. I also have nystagmus which hasn't helped either. I said "used to be" because then that "ten or so years ago" happened and I went through cataract surgery which changed the whole situation to where I don't see well but glasses won't help anymore either.
@@R3cce I think I do but I am not sure. I do have double vision ( only for bright objects though and it gets better when I do eye exercises). But my doctor told me that it's because of the difference. I got my glasses yesterday and I still see double. I think I will have to make a visit again. I hope it's not astigmatism😣
@@snowflake7952 You can check if you have astigmatism on google. Very simple test. It is basically a dial with radiating lines. If all lines are equally clear, then congrats, you don’t have astigmatism, but if some lines appear clearer than others then you have astigmatism. Just search “astigmatism test”
My prescription is Right -5.25, cyl 1.25 WTR, Left -5.75, cyl 1.25 WTR. No wonder I live my life in Glorious Fuzzy-Vision without my specs! Also, not keen on driving at night.
I have been myopic as long as I can remember and I have a mild astigmatism in my right eye. I have no clue what the numbers are all I know is that when I am asked to read the smallest line, all I can see is a white blur and cannot see any black on the white blur. So I cannot read anything.
I have myopia -6.50 and 7.00. They have improved from -7.00 and -7.50. The blurring is not a true for of my vision. The -10 is more true to the vision.
I really wish if I can see the difference between this myopia & normal minus compared side by side in light and dark with this multiple level/intensity of the case.😇😇
Hi doctor, l went to an optometrist and he said that my right and left eye is +0.50 and gave me lens too which he said that it's going to control the brightness of my eyes. So doc pls I need you to explain it more to me
Yeah bro u lost me after u entered that cat park showing that number 10. My prescription is +9. So I’m assuming I have -9 vision. And I can see like a -1 with no light
Already at -4 diopters, you can expect 20/400 vision So -10 would mean that you will begin to see blurry if something is further than 10 cm from your eyes.
@@R3cce so what my visual aquity actually is with this prescription? can you calculate it? also blurry zone starts from 5cm away at left eye and 40 cm away from right eye
@@NightFlutter I see. If he's not short sighted then he's long sighted? It can only go one of two ways. It'll be + whatever. Or he has severe astigmatism I suppose. I'm not sure the exact numbers matter though.
@@NightFlutter He might wear them because either he has to spend a lot of time studying or sit in front of the screen. I was recommended to wear glasses as well for the same reason.
I’m impressed at the accuracy of the distances! I’m a -2.75 in one eye and -3.25 in the other, and after 30cm, object dependent of course, it’s terribly hard to see!!

More important, the blurring shown in this otherwise fantastic video does not take perspective into account.

The loss of sharpness in face features is the most important social effect. You won’t recognize familiar faces anymore, even with mild myopia.
Yes, this happens even with -2, walking on the street uncorrected, you won't be able to see anyones facial features until they are within 5 meters pretty much. My vision has gradually worsened the past few years, from -1.something, to -3~ish (Haven't had it tested in a while), and slowly faces just disappear. People on the street are just blobs of color, faces are a blur. Uncorrected I recognize people by other tells, and sometimes I can only recognize them when they are within 10 meters.
Even with this video, I can't imagine what it is like to have -10 in reality. I expect the whole world to just be a haze, almost like a kaleidoscope of light and color, but no definable features.
@luka188 I’m -9.5 in one eye and -10.5 in the other, and that’s exactly what it’s like. Just random soft color areas blurring into each other everywhere. It’s not necessarily unpleasant. It can be kind of relaxing, actually. Like I kind of feel less self conscious and more at ease, as if no one else can see me either, haha. But it’s crazy to think of how disabling it would have been for most of human history, before we had glasses.

Yeah… he already had -20 myopia when he was at school. Now he wears -38 left eye and -37,5 right eye. Thankfully he said his eyesight haven’t gotten worse in the last few years 👍
Linda, look into lens replacement. It changed my life.
@@nancyeaton731 Yup! Getting it done in August. Cannot wait!
I've had a driver's license for 45 years and been a high myope longer than that. Your video finally explained why I never like to wear sunglasses while driving, much to the dismay of my mild-myopic family members. I need all the vision I can muster while driving, so I prefer to wear my distance-only prescription (not progressives) with large, clear, untinted lenses.
3:47 As a 15 years teenager seeing this and having a -1 Myopia. This is truly scary. I have worked to stop my myopia progression and trying to regain my vision. Even at a -1 Myopia which is considered Mild and not very bad or extreme, this comparison at 3:47 20/20 to 20/40 (I think 20/40 is -1) is terrifying! And thw worse the vision gets, ofc it's harder and depressing... I wish it to no one and may God let the people see the best... Amen.
This is garbage.. im -8 and -7.5 and this is nowhere close of reality.. those simulators are way off of what reality looks like! I see WAY WAY better that what you’ve seen when i sont have my glasses. Dont worry youll be fine
20/40 is not quite -1 im pretty sure; probably closer to -0.75. I used to have 20/40 and 20/70 two years ago, but its gotten much worse. I now have -1.75 and. -1.50 which is closer to 20/100 :(
@@Melanochrysums I had -0.75 right (20/40) and -1.25 left (20/70) that was 3 years ago when I was 9. Now it’s -3 (around 20/300) in my right and -5 (around 20/500) in my left.
This was great, especially the indoor outdoor differences and the book distances. I remember taking a picture of a building once and being astonished that the text on its roof was legible on the photo but not to me. That's when I knew I needed glasses.
Would be nice to see this with human faces as the subject. I'm sure you've heard the "you look prettier without my glasses on too" joke/comeback, but what is it actually like? Do human faces become unrecognizable, at what distance?
I'm sure there's also embarassing stories to tell of people not recognizing their friends because they weren't wearing glasses.
Yes faces would be interesting to see, I have -6 vision and the few times I’ve been in public without glasses or contacts I felt completely lost not being able to tell who anyone was!
I don't have myopia. I have presbyopia and I can see faces better without glasses. I can't see computer screens without my glasses, so webcam calls get weird because I am looking at faces on a computer screen.
I have a mild case of just -0.75 myopia and at night I can't recognize faces at all. I have to get into talking distance in order to see faces clearly. All people around me have blank slates as faces. It sucks.
I recognise people by their movements, walk, posture, style, voice. When I’m on a computer, I take off my glasses, (stupid multifocals, have to tilt my head back to use the bottom of the lenses to see the screen, hurt my neck). I also take them off when it rains and I have to wipe them. If I’m in public with glasses off, I will not be sure if it’s the person I think it is.
@@jjgaming901how much distance you can't recognise face at night
Great video! When i got my eyeglasses back when i was a teenager, it read -4.75. As i wore them all throughout my life, my latest grade is now at -3.50 and -3.75 in each eye. These new glasses were made less than a year ago.
I'm turning 40 this year, and i noticed that whenever i read words closer to my eyes, they tend to blur now compared before, so i have to adjust and move farther whatever I'm reading. I think it's because I'm entering the stage where my eyes are starting to get older (they say it starts at 40) so I'm reminded everyday that not only do i have myopia, but would also have to contend now with early onset of presbyopia. 😢
Thank you for the efforts and time you spent on making this video 💖
I've always been scared to take off my glasses outside since I'm almost at a -6 with my glasses but I'll have to try it to see the difference!
Holding a book mere centimeters away in order to read it is certainly a familiar feeling (-10). I actually find it quite advantageous when working with very small objects to be able to take off my glasses and focus in right up close without the need for a magnifying glass. I imagine this would not be possible for people with a more distant depth of field.
An interesting note about having such a close and narrow depth of field (and binocular vision): With uncorrected vision, I can no longer focus on an object with both eyes at once, because once something is within my far point, the separate images from each eye are too different to be reconciled. Whenever looking at my phone in bed, I always have one eye closed, otherwise it's impossible to see. Sort of like trying to focus on anything while cross-eyed. This is something that the single-lensed camera cannot replicate.
The shot of the church shows very well how the world turns into blobs of colors for myopes. We can still see shapes, especially when there is strong contrast, but details are all but absent. Love the Jinx mural!
I have to read and watch stuff with one eye closed when I don't have my glasses on at night too! The more you know 😂 (-6/-7)
Same i close my left eye at night when im using phone. because i don't wear glasses and my left eye vision is terrible.
@@lukasg4807
Looks like near vision is troublesome after lasik😂
I agree I can see insanely good up close but can’t see shit far away
I'm only -5.75, with added astigmatism, and sometimes reading a book is more comfortable without my glasses. The words seem more crisp without
Thank you for making this video. It was very useful in showing someone I care about why it's terrifying when I don't have my glasses in public.
One of the things I rediscovered after starting using glasses were the reflections. I didn't notice them before. Especially cars became very reflective. I think it could be a great material if you film naturaly reflective surfaces with different grades of myopia.
In my case also, the thicker edges of the glasses would also distort whether I thought passing cars were coming into my lane.
I literally just asked a question on another of your videos that things seem blurry at night in the distance but not during the day. Then went through your videos (after subscribing of course) and found this which basically answered my question! Definitely going to ask about this next time I get my eyes checked
This is awesome! I have -2 and am waiting on getting my contacts for the first time! I totally notice this about the lighting!
My vision is about -7.5. There are a couple things I have noticed. I've started wearing my glasses for longer periods of the day rather than my contact lenses to try to give my eyes more of a break. As an experiment, when I take a walk I take off my glasses and walk for a while to see the world uncorrected. I've noticed when the sun is very bright, there are moments I can almost see the texture of the pavement. On a cloudy day not so much. Another observation is more of a question. My eyes drip like crazy when I'm wearing my glasses. Why is that?
@@R3cce yes
Same when sun is very bright i see much better. at cloudy weather or at night my vision getting more blured
@@badrikokaia4603
There is a reason why. When your eyes are exposed to bight light (sunlight), your pupils contract and become smaller. Less unfocussed light enters your eye and blurry vision is less noticeable. In low light your pupils dilate to let in more light. More unfocussed light enters your eye and the blurry vision is worse.
Interesting video. I have had myopia since birth, prescription currently -13. My far point of focus is 8.8 cms and near point 6.9 cms, so a very narrow depth of field. With spectacles my vision is 20/20 on the right and 20/15 on the left, near point 20 cms, far point right to the horizon.
Incidentally, with extreme myopia, the image doesn't only get more blurred it also breaks up and fragments. The best example is looking down a street at night without specs and seeing how the small street light bulbs in the distance become huge circles of dots, almost like a large dandelion head which has gone to seed! The camera does not mimic this.
Do you have night blindness. Apparently people who are highly myopic can’t see well in low light/dark.
@@R3cce I don't have night blindness fortunately.

This is great! You have a really great understanding of the optics issues and have an inspired way of illustrating them. And what's more, you are obviously very interested in your field. Love it.
Thank you! Time to share this with my wife.
This is great explaination, I want to add up more information is that the blur is not the only thing but our eye trying to adjust itself cause huge irritation, annoying, eye strain and the tired of the eye which make the feeling of putting out the glass much worse than watch this clip
Great topic and video Antonio. Your presentation is admirable - but the camera lens blur simulation does not quite describe the effect - especially in lower light/indoor settings. I would say that blur is not as bad as you show here in interior lighting scenes (maybe due to how rods and cones work in different lighting conditions?). Also I would say most folks who have myopia also have slight astigmatism as well, which does not offer the same even “blue filter” when blurring a spherical lens evenly using something like Gaussian blur. I find that while an image at -4 is blurry, the average myope (without bad astigmatism) can still resolve certain elements of these scenes with perceivably less blur, while having the macro scene still blurry, if that makes any sense.
Hi Antonio the Optometrist! The reason Adelaide is called the city of churches is because Adelaide was the first city in Australia, maybe the world, where it was legal to practice your own religion, regardless of the denomination! Thanks for your video!
Weow.. the more you know 🤷🏼
Former high myope -10 with -3 astigmatism. I had a lens replacement in both eyes for cataracts four years ago. I’d been wearing custom gp contacts, monovision, but was becoming increasingly intolerant of them and wearing glasses wasn’t ideal for driving due to edge distortion. I had night blindness. The lens replacement changed my life! I opted for monovision so I wear readers for close view in low light, but otherwise I need no glasses for distance, day or night. I almost cried when seeing your examples of what my vision was before. People really have no idea how debilitating high myopia is. I am so grateful that the lens replacement healed me. It was a miracle.
To add a bit more about the night blindness, I am not sure if this was due to the monovision with the gp contacts, or residual astigmatism that was uncorrectable, but I had no depth of field ability when judging oncoming headlights. There were also halos. This made night driving extremely dangerous, not only for me personally, but for all other people on the road driving with people who have this affliction and still try to drive at night anyway.
@@nancyeaton731
People with high myopia can find it more difficult to see in low light/dark. I have a friend with high myopia and he is not allowed to drive at night.
hey im - 11 high myopia and my doctor suggested me clear lens exchange, im 32 yo, would i go or not im worrying it will not be successful coz of high grade and still wearing eyeglass or retinal detachment or maybe some laser prk after surgery.
This is such a good video and I’ve sent it to all of my friends since my myopia is ~18R and ~10L
-18 for real 😮I mean doesn't it become harder when it comes to day to day work
@@Chanbro4yes… it absolutely does. And my current issue is that my glasses are so heavy that they’re giving me pressure sores on my bridge. I’ve gone into the clinic almost every other week since November without any luck in getting that to stop
Very helpful! I know I have astigmatism and myopya since then because of the Checkups I had. But I haven't had my new eyeglass as of now, it gotten worse I know. Hoping to get a new one I miss the clear vision I had before huhuuu
Thanks again for this video of yours! Everyone who don't understand what we say will believe if they see this coz they tend to laugh or don't believe lol.
*myopia*
thank you for making this video, I'm -14 and definetly will share the video so people can see (kind of) what i see
My right eye had a problem with the retina separating from the back of the eye. I went in emergency surgery and they were able to reattach it to the back of my eyeball. The surgery was a success as far as restoring my vision but I developed a caterac (as 90% of patients with this surgery do) and had to have a lens replaced. I can still see with this eye but my focus at the center of my eye is fuzzy. I can see a person in front of me and make out most of the details but not much of the fine details. Now my left eye is what my right eye was before the need for surgery. I can make out every line printed on a $100 dollar bill as long as it is within 6 inches. I just can't read the dashboard of a car without my glasses. My vision I think is -8.50. BUT the iris of my right eye is always comparatively dialated. This is why it appears that on bright sunny days I seem to be winking at people. In reality, I close my right eye because the brightness is painful and most everything I see is washed out.
Antonio,
You have a nice POINT OF VIEW!
(POV).
my right eye is around -0.75 while my left is around a -2.75 so it leads to very odd looking vison along with my astigmatism
This was great!
너무 유용한 정보인데.. 한국에는 이런 검안유튜버가 없네...
This was pretty interesting. I'm very close to the -10 shown in the video (-9 in my right eye, -8.75 in my left), along with a bit of astigmatism (-0.5 at 95 degrees in my right eye, -1.25 at 25 degrees in my left). What I find really fascinating though is that my far point is closer than what you measured for someone at -10 - mine is 8 centimetres (basically the length of my index finger). It makes getting my photo taken for my ID particularly maddening because without my glasses on, I can't see where the camera's lens is and therefore have no idea if I'm actually looking at it 😅
I'm close to blind in left eye I have -7,00 with -9.00 astigmatism at 88 degree. I dont have any close or far focus points i can see best from 5 cm away if i take something more closer or further it gets more blurry.even from 5 cm its still little bit blurry. But my right eye is close to normal vision I only have -3.00 astigmatism at 117 degree my vision is perfect at daytime but gets liitle bit blurry at night. Im 15 years old and i wish that my left eye stopped progressing more. 😢
Also i don't wear glasses
Thank you for this and the work you put into it. Most of my family are at -4 or -5 but I’m at -10.5 and it’s very hard to explain that without glasses I can’t even navigate the house. I’ll send this video.
I have hyperopia, but I’ve always been confused when people say that individuals with hyperopia can see distant objects okay but have trouble with close up objects. My prescription is +8.5 in both eyes. Without corrective lenses, my distance vision is similar to the -10 you simulated, but instead of getting better as you get closer to the object, my up close vision it is equally as bad as my distance vision, so moving closer or further has no effect on what I can see.
Hi Antonio, love your videos! Could you do a video on whether or not constantly upping your glasses prescription makes your eyes accumulate to worse vision. My friend saw a study which apparently said there were links, but I don't know how true or not this is?
or could you do a video on why eyesight degrades faster as a child/teenager and tends to stabilise as an adult?
Mine was -3, but because I’m a generation X I visited the opthamologist that my dad happened to be seeing(so no formal examination) and after getting my pupil response said there is nothing wrong with my eyesight. This carried on through middle, into high school.
I have oblique astigmatism and myopia,could you by any chance do a video like this one and the astigmatism one combined?
I’m finding this really interesting.
Just found your channel and I have never been so curious about my vision as I am now haha, like I have been wearing glasses since I was 5 or so, so I never really gave it much of a second thought till maybe a year ago, and now your videos give me even more curiosity.
I use to wear an eye patch when I was a kid, still don’t know if that helped? That could also be an interesting topic to discuss, I hated wearing that thing as people looked at me funny and said things. I drew suns and moons on those eye patches, I used to stick them on the door, I remember my door being full of drawn eyepatches
If I use an eyepatch now I’m 22, will it still help improve my vision or does it just work on kids?
If both of your eyes look in the same direction and have relatively similar prescription strengths, then yes, the eye patch worked.
@@mydogeatspuke they almost look in the same direction, one of them is slightly off (not really noticeable), but if Im really tired or I get nervous it's more easy for it to be noticeable I guess (without glasses I mean, with glasses I can't even cross my eyes , which I also find kind of weird)
I think it's because Im not focusing so much on making it work, I relax my eyes if that makes sense. Also if I try to focus on using my left eye which is the lazy one I can make it completely straight but I can't see anything when I do this.
Btw thanks for your quick response, it really does help me out!
@@meirienda that all sounds normal to me, including not being able to see if you force your lazy eye! Your brain automatically blocks the vision so you don't see double as it's corrected to see and work with your other eye at a specific position. It's quite clever how they correct it tbh!
@@mydogeatspuke wow, I didn't know that was because of the correction they made, thanks, this conversation has helped me understand a bit better!!
Hope u have a nice day
I hate cloudy days with pure white sky.
That punishes me a lot and going outside feels impossible since my eyes can't take too much light reflections from many angles

Love ur videos
Yes, visual snow!
I have to disagree with the examples shown though, the indoor examples were way too blurry in comparison to how I see with the same diopter like -2 aint that blurry and -2 outdoors also looks to sharp

Hey Antonio. Thanks for your work. I've noticed by myself that blue led-signs, for example at shops, are way harder to read for me than other colors. Don't know the reason or if this effect could explained in an video.
Greetings.
I have myopia at around -4.00, most of it probably results from me as a child thinking "I wonder what it's like to stare at the sun" and then actually doing it
One thing though, I actually enjoy myopia sometimes. I know this sounds like the punchline to a joke, but I find things like festive lights look better, or light reflected off water or whatever. Bokeh, but in real life, just walking around. I kind of wonder if anyone with astigmatism likes the look of lights at night.
Good for you. I have myopia and astigmatism and can't stand bright lights. The ones in shopping malls and neons inside offices are unbearable. Before wearing glasses, I avoided going out at night for the same reasons. My corrective lenses are photochromic, and wearing them is really a game changer.
But what exactly is your prescription all around for indoor and outdoor objects? I know glasses and contact lenses the diopter numbers are different, but for some reason I see better with lenses than glasses.
I strongly believe that the -1.00 and -2.00D images are quite inaccurate... With a -1.00 in my left eye without correction I see what you are showing as -4.00 or -5.00D.
OK, I reacted too early :D
Means ... what
Could you explain why suddenly I need readers? Also, why until now, my vision with contacts has be great but since needing readers it sucks. My Rx hasn’t changed either -2.5
I have myopia around -2 or slightly worse, probably from using the computer when I was young. I've managed to not break my glasses for over 10 years, wearing them sparingly only when needed. I've not been to an eye specialist, do I can't say my exact number.
But I don't "suffer" from my near sightedness. I don't have a house anymore and don't need to work in the garden. I don't attend school and therefore don't get laughed at for my glasses. It would be far more troublesome if I couldn't see up close. Even work outdoors needs precision.
An optometrist prescribed me a compromise glasses around -1.75. When I first put my glasses on, I loudly exclaimed like a fool in the optometrists office. I wear glasses when walking outside in the city and going shopping to search products on shelves, and avoid attracting security. I don't need perfect sharpness read text or distinguish a red light. The title of the book would be readable at some distance to the camera.
There is still a range of focusing ability unlike your camera. I don't get how you derive meters from the diopters, which are a correction on top of the range that the eye has.
How far can you see crystal clear without specs
About 40 centimeters.
Is there difference between vision without specs and with specs at night compared to day
What has been said about the apperture size sounds reasonable and is probably true. I can't see the effect, because I see better with good light anyway, and there are other factors like if I take off my glasses I see very poorly initially.
I can't read with distance glasses on at night, so I have to look past them. A weird feeling.
Sitting here with tablet screen about 25cm from my face, maybe less.
Finally a video who can show that as a myopic I see things blurry, but still can see how many fingers they show me lol
One of my eyes is short sighted the other longsighted, plus other issues. My optician was adjusting my glasses and told me to pick them up in an hour. So I walked down town New Plymouth, New Zealand this is, well my eyes did not cope well at all, that hour. But I found it fascinating all the same. Picked up my glasses and home to have headache meds. I laugh about it now.
Please please please use shellen chart with -1 to -10 myopia
Don't know if it's due to the screen effect or what, but I have a hard time resonating with the comparisons. I am now trying on -3.00 and -3.50 lenses as I am preparing for Lasik surgery. I also have medium astigmatism on my right eye. No way my vision without lenses or glasses is as bad as shown in the video, both outdoor and indoor. At daytime I can - with some effort - read license plates of cars parked across the street from my window (20m away) with no correction. And with -3.00 and -3.50 lenses my vision does not seem to be hypercorrected, actually it feels like I am still missing 0.25/0.50 per eye. Am I mixing measures up or how can this make sense?
My prescription-1.25 am i in danger ? I don't always wear glasses, only when I'm at school for patient vision
Have you tested Alcon total 30 contacts? Do you have a video on that yet? I would love to get your opinion.
I remember, once I left my rx glasses in the locker room for swim lessons. I felt so uncomfortable walking around because it was so blurry without my glasses. I ended up ordering some rx goggles.
I wish you'd have put examples with people/people's faces. I can navigate, with difficulty, being in a known street/area without glasses, but it is unbearable to interact with people without putting my glasses on - without seeing faces, I cannot tell who is talking in a group; it feels awful.
5:48 - great example
I think this wallart is undermined, you can`t see face lines with -5 and gym scene is exaggarated, you don`t have complete bokeh with - 5. The main thing what is going lost is smaller details like letters and face lines
The part of the video that best shows how I see things would be at 6:58
Im myopic and astigmatic both in the -5.0 range in both eyes. Im in my mid 40's and so am starting to struggle with presbyopia. I guess its multifocal time but as an optical mechanic (have been out of the job for 20 years) i know im going to struggle with adapting. Not looking forward to it.
I'm short sighted with astigmatism too, but have also needed reading glasses since I was 28. I'd like to try varifocals but anything of a decent quality for driving would cost a small fortune. The total loss of peripheral clarity is what concerns me most, and of course the fact that they can never get my prescription right so I always have a headache and squinting. I'd rather not make it worse than it needs to be!
@@mydogeatspukeBro, why would you need reading glasses when you have myopia. Myopia means that you can see clearly in front of you, but not in the distance. People who are myopic with presbyopia can simply take their glasses off to see up close.
@@R3cce why would you need glasses at all if you're incapable of reading to begin with...? I said ALSO. In addition to my short sightedness I also have early onset presbyopia. I need distance AND reading glasses. And no, I can't just take off my distance glasses to see up close, and not only because of my astigmatism. If it was that simple, there would be no need for graduated lenses. Stop being silly.
@@R3ccelike what the op said - our eyes start getting older by the time we reach 40. This is currently happening to me now. I'm turning 40 this year, and have been myopic since I was a kid. Now I have to move objects/books/etc farther away because what used to be clear when I set them closer to my eyes are now blurred as well. That's why multifocal prescription glasses exists.
To the OP, I feel the pain. 😢
Great video! I'm not sure what my actual prescription is, but pretty sure it's -7 in my left and -3 in my right. I have a question: can you explain why when I look in the mirror without glasses on, everything in the background is still blurry? It doesn't make sense to me because the mirror is not that far away so it shouldn't be blurry.
It's because the image of the background is at same distance behind the mirror even though u are closer
Ie let say a clock behind u is at a distance 10 feet so when u see the mirror from a feet the image is actually 11 feet away from u That's why it's blurrier
I wonder if some -0.5 or -0.25 people have only night myopia.
I watched your last vid and thought those diopters were rookie numbers
It's always wild when I accidentally find Adelaide on the internet.
I recognised far too many of these public spaces. XD
I dunno if it was because I was born with it or what but I don't agree with what is shown on the video.
My sight used to be somewhere around -10 to -12 from when I got my first glasses until maybe ten or so years ago. With those numbers there wasn't really any difference anymore if the chosen lens was -10 or -12. I also have nystagmus which hasn't helped either.
I said "used to be" because then that "ten or so years ago" happened and I went through cataract surgery which changed the whole situation to where I don't see well but glasses won't help anymore either.
My prescription is -1.00 for the right eye and -0.25 for the left. I wish I had taken better care of my eye😔
Your prescription is still very low. Nothing to worry about.
By the way… do you have astigmatism?
@@R3cce I think I do but I am not sure. I do have double vision ( only for bright objects though and it gets better when I do eye exercises). But my doctor told me that it's because of the difference. I got my glasses yesterday and I still see double. I think I will have to make a visit again. I hope it's not astigmatism😣
@@snowflake7952
You can check if you have astigmatism on google. Very simple test. It is basically a dial with radiating lines. If all lines are equally clear, then congrats, you don’t have astigmatism, but if some lines appear clearer than others then you have astigmatism. Just search “astigmatism test”
3:16 that explains why my vision gets bad at night lol
Why does my -3.75 looks like the -10....😭😭😭
As an -1 (not prescribed) I'm very unlucky
I am -9.00 myopic in my right eye, and -8.25 myopic in my left eye. I also have astigmatism in both eyes.
At far distance without any accommodation power
The image of
-10.00D of myopia is the same as +10.00 D of hyperopia
When you notice nothing changes
My prescription is Right -5.25, cyl 1.25 WTR, Left -5.75, cyl 1.25 WTR. No wonder I live my life in Glorious Fuzzy-Vision without my specs! Also, not keen on driving at night.
I have been myopic as long as I can remember and I have a mild astigmatism in my right eye. I have no clue what the numbers are all I know is that when I am asked to read the smallest line, all I can see is a white blur and cannot see any black on the white blur. So I cannot read anything.
It's interesting that many visuallly impaired people become optometrists (or similar kinds of professionals).
I have myopia -6.50 and 7.00.
They have improved from -7.00 and -7.50. The blurring is not a true for of my vision. The -10 is more true to the vision.
I actually found someone on TH-cam that has -38 myopia. Crazy
th-cam.com/video/v-Rbt4JNiNc/w-d-xo.html
Does that mean at night, you see things even more unclear??
I really wish if I can see the difference between this myopia & normal minus compared side by side in light and dark with this multiple level/intensity of the case.😇😇
Hi doctor, l went to an optometrist and he said that my right and left eye is +0.50 and gave me lens too which he said that it's going to control the brightness of my eyes. So doc pls I need you to explain it more to me
My prescription is -7.00
Yeah bro u lost me after u entered that cat park showing that number 10. My prescription is +9. So I’m assuming I have -9 vision. And I can see like a -1 with no light
Does 20/400 vision equals to -10.00 ??
Already at -4 diopters, you can expect 20/400 vision
So -10 would mean that you will begin to see blurry if something is further than 10 cm from your eyes.

As a person with myopia of -2 I don't see like that
Can we treat this naturally
You can't mimic this with a camera it's just different I'm minus 6 and the minus 10 shown in the video is what my minus 6 looks like in real life.
I have -0.25 glasses but tbh I think I need something stronger. The -1 pics look very familiar to me 😂
At 100 metres I might be able to see a person, if they move.
what's your prescription if you're not myopic?
...? If you don't need glasses to correct near or far sightedness then you don't have a prescription, because you don't need correction.
@@mydogeatspuke he said he don't have myopia but wears glasses so im asking whats his prescription in his glasses
@@NightFlutter I see. If he's not short sighted then he's long sighted? It can only go one of two ways. It'll be + whatever. Or he has severe astigmatism I suppose. I'm not sure the exact numbers matter though.
@@NightFlutter He might wear them because either he has to spend a lot of time studying or sit in front of the screen. I was recommended to wear glasses as well for the same reason.
@@mydogeatspuke not every who wear glasses have eyes problem
press left arrow key at the begingin of the video to see him chewing gum
I’m impressed at the accuracy of the distances! I’m a -2.75 in one eye and -3.25 in the other, and after 30cm, object dependent of course, it’s terribly hard to see!!
I was at about -5 on both eyrs, had lasik done on the 3rd of march. But what you show here seems about right
I have a unkal he has -8.00
Nice 👍🏻👍🏻
4 here 🖐
👍🙏
I’m 11 and my power is -7.5
