The lens (which is not) you were referring in front of the eye is a cornea, and it doesn't change its shape. The crystalline lens with the help of ciliary muscles is responsible for focusing the image on the retina through accommodation.
Damn bro.. I just came here to learn.. and your comment about "when you were thinking about why things weren't as upside down as they used to" really fucked me up to the point of existential crisis..
We become more myopic when we use distance glasses or contact lenses for extended periods of close work. Don't use distance glasses or contact lenses for close work. Use reading glasses over your contacts for close work.
Scatterbrained, back-and-forth, non-methodical presentation. If you think this way and have a short attention span, you'll love this. If you are methodical and logical, run.
Using biconcave lens to treat myopia seems theoretically correct but when I actually observe my specs, the lens seems something like convexo-concave but definitely not biconcave.... How do these lenses (not the biconcave/biconcave ones) work?
Mihir Kavishwar Similar to smooth-transition bifocals? I think they just ease the transition between the two lens's curvatures so you don't get a line. I would need to get my hands on such a lens and play around a bit. Cool!
Whoa I don't use bifocals I am still a teen!!.... I meant one side covex other concave. In your next video you drew the shape of your specs, something like- (( except that the inner side is more curved..... Transition bifocals definitely seem cool though :D
Optometrist here, the type of lens most people use nowadays are called menisscus, its bascally a convex-concave lens, where if you are myope the concave part of the lens has more refractive power than the convex part, and viceversa if you are hyperope. Biconvex and biconcave lens are used in cases where the pacient has a really big refractive problem (something around -+ 10 dioptres), but nowadays we use conctacts instead of big heavy eyes-changing size lenses (sorry for bad english)
Only a Qualif-eye'd Professional can properly educate your eyeball organ, you know Music teachers also teach Organ so ya might wanna consult one of them Organ Training. It is true that you can train your Organs tho ya know like your Kid Knee Organs, you trained those and now you don't wet your Pants anymore. 😜
Good question. The same correction can be achieved by being flat or even convex on the front side and increasing the concavity of the back side. This fits the human face much more nicely!
if all objects are focused at the far point in myopia why do we see objects normally at same distance as they are .I am researching on this from an year , im ready to give out 50$ for the explaination .Any phds or opticians kindly help and be as technical as you can.
What about a pathetic brain? Any correction suggestions? i see you fairely active in this video, wishing i'd get the secret :D. Greetings of a lost student
lol pathetic eye thanks alot '/// I have been wearing glasses since age 1 i have Accomodative Estoropia im extremely hyperopic +4.75 and +6.00 near point each eye and Im cursed with Astimgatism -2.50 cylinder asgitmatism horrible combination to be hyperopic and have extreme astigmatism :( Im also the only one in my family with this problem everyone else in my family has perfect 20 20 crystal clear vision. What about hyperopia can they get lasik surgery? According to my opthamologists and optometrists when i rant to them about my pathetic stupid eyes im STILL considered extremely fortunate and blessed that my vision is at least correctable. I would think a person with even the strongest glasses would not be able to see due to retina problems cataracts etc low vision aka legally blind now thats a pathetic eye.
these are the funniest and best explained physics classes i've ever seen. thank you
this man needs more appreciation.. these videos are so helpful and I love the energy
you're actually explaining better than my teacher.
Cata Yo ryt 😂

You are hilarious! I now have a crush on your hands.
Norma Marie same😙
I learned so much and you were hilarious through it.
That's high praise! You're welcome and thank YOU!
PLEASE do a video on the physics of laser eye surgery. By Friday would be recommended bahaha
nice lense of humour !!
oh my god..
The ray tracing starting at 6:31 is wrong. A point in the image is smeared across a section of the focus plane.
Damn bro.. I just came here to learn.. and your comment about "when you were thinking about why things weren't as upside down as they used to" really fucked me up to the point of existential crisis..
"The true freaks are the people whose eyes focus too much." LOL!
Can you please do a calculation!!
Some evil doer magnified sound in Albuquerque........😊
wonderful video, very helpful!
What if the upside down green I see is the right side up blue you see......?
thankyou so much dude
enjoyed learning!!

Omg....you are so good!
I am a licensed amateur optometrist!
So when ur myopic, does that necessarily mean that you are near-sighted?
AgentSniperYT yeah
The lord of the flies referece :-)

Mihir Kavishwar Ha! At any rate, I would imagine that the vertical focal length is different from the horizontal focal length.

Huh, I always thought Shuster was pronounces as in hunt.
i wish i could triple like this
I could smell my eye melting. LASIK.
Myth or fact, does continuous wearing of eye glasses weaken your vision over time?(Discounting the effects of aging on eyesight).
+JG Oooh - I have heard about some people who believe that, but the studies that indicate it have been largely discredited.
Ah, I see! Thanks!
My eyesight has gotten worse and worse since I started wearing them at like 15. Every time I go to the eye doctor my eyesight is worse
Had lasik 8 years ago and now my eyes are getting myopic again. Any recommendations? They don’t recommend re doing surgery.
awesome 💖💖
Mabye your eye is green, which in the case of Jacksepticeye, is true.
But it also mean that you can train your eye?

😜
why aren't glasses for myopia concave on both sides?
Good question. The same correction can be achieved by being flat or even convex on the front side and increasing the concavity of the back side. This fits the human face much more nicely!
Doesn't your eye size stay the your whole life?
THANK YOU REGARDS
"Your pathetic eye" that was hilarious!! xD xD
No, way In Davies joeys I am going to get laser eye done! No! Thank you! Check please! By the way your very helpful :) haha
I’m 14 and I’m trying my hardest to become an optometrist
"The problem is, you can't start a fire with this" lol
if all objects are focused at the far point in myopia why do we see objects normally at same distance as they are .I am researching on this from an year , im ready to give out 50$ for the explaination .Any phds or opticians kindly help and be as technical as you can.
Well now I want instructions for measuring my cylindrical diopter too!

You’re so dope. Lol
This guy is amazing haha
9:54 😂😂😂😂😂😂😂
my eyes are too small yet am myopic
I got a 7 cm Window 7 cm from my eye 🧐
You know what that means don't ya😲
Guess My Far Point🤔
😝
Yep you guessed it
That they have myopia hahahaha
Odd but informative
