Hey American institute of human anatomy I was just wondering if you guys can make a video about wearing eyeglasses on why do humans have to wear eyeglasses to keep up with better vision of what are the reasons for the naked eye to be 20/20 vision.
Makes you realize how fragile our eyes actually are. I’m thankful I was born with healthy eyes and good eyesight. Remember to wear safety glasses when doing anything that could cause damage to your eyes!
I've only now discovered just how fragile our eyes are. Not a week ago I suffered vitreous detachment in my left eye, which has now left me going INSAAAAANE!! Kazillions of little dots in my field of vision and these annoying opaque floaters that get in the way of everything. My overall vision is as good as it's ever been, there's just a bunch of s&#t in the way and so I'm constantly screwing with my eyes to get the floaters to move. Vitreous detachment _can_ lead to more serious problems like retinal detachment, so it's really important to maintain eye health to the extent we can do anything about it. Vitreous detachment I guess is pretty common, especially in those of us over about age 60. What's MORE amazing (and I was suspicious of this when my ophthalmologist told me this) is that eventually your _brain_ will compensate for all these tiny "thingies" crowding your vision and eventually you won't notice them as much. I'm already noticing that with the kazillion tiny dots -- not so much the floaters yet, but I'm patient, we'll see how this shakes out.
As a person who had eye problems since birth (herpes and after that came floaters), I can confirm you how fragile eyes are and how important is safety gear and other safety practices.
I actually think that they are far less fragile than often thought. The sclera is very tough and also very sensitive to any kind of touch. I got jabbed in the eye good with a stick once and the pain was terrible but my eye was fine.
@Dusan Jovanov I thought I was the only one who knew the pain of optic herpes. Dear God it's a good thing the outbreaks only last about a couple hours. I couldn't imagine having one for a whole day or even a week.
I can't help but think about all the sights these eyes must have seen in their living lifetime and what stories they would tell if you could play back those images...
@@tville4358 I’m using the word ‘magical’ here in its second adjective form relating to the words ‘beautiful’, extraordinary’ or ‘magnificent’ instead of the obvious supernatural meaning. Clearly English isn’t your strongest pursuit…
Strange to think those eyes were the witness to a whole life the person they belonged to experienced. Sobering and powerful thought. Really cool video, thanks for this.
Eyes and evolve should never go together. The eye is the most designed mechanism in the body it’s wired with light sensitive cells billions of them. The eye is more sophisticated than any man made camera around. I personally detest the word evolve. It’s a sneaky disingenuous way of trying to discredit God- the designer of the eye and human body altogether.
The dissected eye lens didn't break during dissection! You can see the lateral arm of a lenticular implant moving around when the probe touches it. This individual had cataract surgery in life, so the lens was removed by phacoemulsification and replaced with an implant. ❤
This is such a cool addition to the video! Thank you for your added knowledge! Do you work with eyes or are you just generally fascinated enough to do research on them outside your career?
@@vortexhunter2112 I enjoy learning about every medical procedure I can, as I aspire to become a physician after completing undergrad. I think eyes are pretty awesome anyway, so when i recognized the implant, I had to chime in!
Not exactly dissection, but I would love a video where you explain the various things an ophthalmologist looks at during a routine eye exam. Like, when they look "into" your eye, what do they see? What are they looking for? Also a video about astigmatism explained with how that happens in a real eye would be amazing! Finally, another thing that is interesting is how laser eye surgery works (do they really scrape off a bit of your cornea?)
Extremely late but I hope it helps. A physician will look at everything during an eye exam, from the eyelids to retina. They might use a slit lamp which is essentially a magnifying glass with light source to examine the eye surface, especially cornea, lens, and the space between them. It's useful to see if there's infection there or for cataract. Then to see the retina and the space behind the lens they will use an ophthalmoscope which is also a magnifying glass with light source. They will dilate your pupils and look through there to see if there's debris, hemorrhage, blocked blood vessel or detached retina. In astigmatism, the eye surface especially the cornea is not smooth. It's like a window with uneven surface, the garden you see from the window will appear blurry
This is weirdly fascinating! My mom (a month or two ago) got artificial lenses implanted because of cataracts. It's fascinating to see what's inside the average eyeball, and what was replaced!
@@jans8449 Hi, I stumbled upon the video and comment section by accident. If you don't mind telling me, how long was your recovery time after surgery to be able to see comfortably?
@@michaelmuliadi6088 Hi Michael, my vision was fine within a few days. I had post surgery checks and sight tests after 4 weeks and I now have 20:20 vision, although I need reading glasses for close work.
Optometrist here : Correction--@2:56--Glaucoma is NOT " Clouding of aqueous humor" Glaucoma is a disease resulting from a pressure inside the eyeball that the ganglion cells can not withstand; ergo, ganglion cells die and subsequently drop out of the retina & optic nerve. Also--@ 2:50--floaters are not normally in aqueous humor; they are typically in vitreous humor. In cases of severe disease based inflammation of the iris, floaters may be experienced from inflammatory cells in the aqueous humor. 🤓
@@ChrisPBacon-ok7ir why are you being sarcastic? I think it’s great to have accurate information under an educational video No need to be defensive over someone sharing something from their field of expertise. Surely not everyone has the same level of knowledge as you
@@ChrisPBacon-ok7ir Well, if you 'knew' he meant to say cataracts then you'd also be wrong. Cataracts are clouding of the lens not the aqueous humour. Not sure why you'd want to try to correct an Optometrist.
This is absolutely fascinating! As someone who’s had 5 surgeries on my eye in 5 years due to a ruptured globe. I’ve had something done to almost every part of my eye. Thank you for the awesome video explaining the parts of the eye!
WOW! Thank you, doctor. You are a natural teacher. You show bite size pieces of important information that sticks with you. More like embeds into your brain. Very much like the process of how we remember "Where were your when..." You are doing a great service to the pedestrian population who would otherwise be ignorant of the wonderful workings of our bodies.
Many years ago, I had an employee that worked for me get into a surfing accident. Both his retinas slowly detached and I sadly observed him lose almost all of his vision (I am sure by now he is blind). I felt so bad, I bought him very large monitors because I noticed he kept decreasing the resolution to see better. So I would be very interested to learn more about what happened to him.
I use to watch this guy on here that's a surfer that is now blind went blind a few years ago. Maybe the same dude? He's famous ig you could say tho he does the voice overs for trailers
I was born with congenital cataracts and had amblyopia when I was small. I'd love to see videos about these topics! Thank you for another fascinating video!
I was also born with congenital cataracts! Mine have thankfully not developed badly enough for me to require surgery at this point in my life, but I found out at age 22 when I went to the eye doctor (all by myself for the first time, my parents never really took me to the optometrist as a kid, which was fine) and the doctor told me about it and mentioned how mine are mild for someone who was born with them, but they’re there. I assumed there were other people like me but I never had the opportunity to speak with one.
Thank you so much for this video - very enjoyable and educational. As someone who has been living with floaters and had laser therapy for a retinal tear, I've always been obsessed with the vitreous humor and the retina. So, it'd be nice to see more details of that on the channel. 😃
I would definitely like to learn more detail about different eye conditions like glaucoma, macular degeneration, and the vision deficiencies that can develop like myopia, hyperopia. Also, I would like to better understand what happens in the optic chiasm as well. Thank you!
Myopia and hyperopia are part genes and part enviroment. Myopic parents tend to have myopic kids. Macular degeneration has many diffrent types, depending on the layers of the retina, and blood vessels, not easy to explain here. glaucoma is pressure related. if your eye gets over above the healthly pressure for your eye it will slowly develop glaucoma.
@@Blaxton9Well in certain cases the environnement ends up being fully responsible for myopia development. I became myopic only at 22-23 because of close up screen time and a new born chronic illness. If I had good habits and not taken that medication making me sick. I would probably still see perfectly today. That sucks and I wish we were thought how to take care of ourselves.
I can't answer that completely cause I'm DUMB but iirc (i got into this stuff like a month ago) the nerves of the optic chiasm move to the LGN of the thalamus before moving on to the primary visual cortex, and then a bunch of other complicated shit happens involving the interconnected shenanigans of the brain layers and subdivisions
Great basic eye overview! I have complicated bilateral uveitis. I’m a “special” patient. I know way more than I ever wanted to about the eye. For people who don’t know how crazy complicated our eyes are-I’ve had 5 different specialist ophthalmologists-neuro-ophthalmology, uveitis, glaucoma, retina, and cornea. To make things more interesting, the glaucoma and cornea problems I have are specific to uveitis patients. I’m at very high risk of a detached retina from the uveitis and familial history. If you ever want a patient’s perspective, lmk.
I know the feeling of being a “special patient.” I have had several retinal detachments and numerous other eye complications/surgeries. It’s scary but I’m glad I still have some vision. Thankful to all the eye specialists out there for sure.
When the two halves of the eyeball were separated, that was both amazing and disconcerting at the same time... 😳😅 11:11 is so thought provoking, and it made me think of the opposite reflective properties of things like convex mirrors that they put on lamp posts to help people see blind spots on roads. The eyes are absolutely incredible, and some are magically beautiful 😊
I have had a detatched retina in my left eye since 1990, and this is the very first time I've truly understood what a retina looks like! Many doctors have tried to explain to me what the retina looks like but I never could truly picture it. So THANK YOU for finally showing me!!! Also, I would love to see what a detached retina really looks like! Thanx!
Definitely would like to see more about nearsightedness and far farsightedness. BTW, I love your channel and the info you provide. Your presentation is fantastic.
I don't think you're art is bad, I totally got what you were talking about. I could follow along and understand where you were leading us. Truly appreciate you explaining our bodies in a way that is easy to see how and why things work like they do and the abnormalities that can happen sometimes.
I am curious if they could preserve the eye with the humor while it is cut in half. Maybe, replace it with some jelly just to model, wha the light has to go throug
@@RelakS__ generally I think organic fluids are a bad idea to keep in cadavers because they can rot. Maybe like you said if they replaced it with a jelly or something that would work, but I doubt the original humor would be easily preserved
I'm very interested in a video going over acquired astigmatism and other age related degenerative changes in the eye. You explain things very well and we the curious really appreciate the work you do. Also, thank you for your service! When you served, was it in a medical capacity? If you don't mind answering. Bio videos for you both would be interesting as well; what brought each of you to the medical arts and so on.
Yes I definitely want videos on diseases like glaucoma, cataract,myopia ,hypermetropia,astigmatism retinal detachment etc I'd love to see that please.❤
I would love to watch nearsightedness/farsightedness, retna detachments also. Love! Love the eye and other videos that I saw learned a lot. Amazing nature of eye and how it adapts to our environment. So intricate, precise and beautiful creation by Lord. Truly amazing. Thanks Jonathan
I have had 2 cataract surgeries, and a vitrectomy. I also have macular edema, so I have been learning more about eyeballs than I ever thought I would need to know. The fovea is supposed to have an indent, but mine was swelling, so my vision was becoming distorted. The doctors still don't know what 's causing all this inflammation because I was tested for diabetes and I don't have it. It's a real drag because I am a graphic artist. Maybe it's because I have used my eyes so much during my lifetime looking at tiny details and staring into light-tables and stuff. I'm in my late 50s by the way. Thanks for showing us that real human eye ball!
I'd be interested in knowing more about "floaters", i.e. what they are, what produces them, and so on. Really, though, I'm fascinated by ALL your videos.
I think that floaters are supposed to be normal breakdown of the jelly in your eye, they are supposed to disappear over time, or your brain compensates.
Floaters are microscopic structures in the vitreous body. They're extremely small - can't be seen without a microscope, but they can float through certain parts of our eyes and either cast a shadow on the retina or cause light waves to flow around them and refract, therefore making them visible
It would be interesting to see if you could do one on strabismus and eye muscle problems (which I grew up with - I was also born with one near sighted and one far-sighted eye)
It was created in its complete state like we see it today in every newborn. And it for sure did not take 500k years! Every smallest detail is developed and “programmed” in the womb.
Evolution of the eye makes no sense without a designer. An intelligent being has to have PLANNED it even if it did evolve. This video has further increased my belief in a Creator.
13:00 Fun fact because we have our cones and rods behind their blood supply(or something like that) which isn't ideal, we have a blind spot where these enter the eye and make it impossible to have photoreceptors there, cephalopods(octopus, squid,etc) have the blood supply behind their photoreceptors so they don't have a blind spot... this is also a good argument against intelligent design.
@@Sonilotos Whoa there friend who said anything about religion, intelligent design is a theory that the universe and its complex life forms cannot be explained solely by natural causes and that there must be a being that created them, it's not my fault this just happens to be the main argument most (but by no means ALL) religions use to disprove evolution, you do not HAVE to be religious to believe in this. There are a lot of things science can't yet explain, but evolution isn't one of them. For what it's worth science doesn't say there is no "god/higher being" there may very well be one at the very beginning of it all but it's highly unlikely he was designing individual animals when the mechanism of evolution can do it all by itself.
WOW … this video will be great for my 8 yo granddaughter ! She’s very curious and is always asking questions about how we breathe and see and hear and what the kidneys and liver and brain and so forth , look like and function . So thank you for making this wonderful video ! I just hope she doesn’t start asking about synapses and neuron’s ! She watched a movie a couple of months ago and then asked me “ What does it mean when the pupils are fixed and dilated ? “ Geez !!! 👍👍👍❤️❤️❤️⭐️⭐️⭐️⭐️⭐️😊😊😊
I'm just insinuating that if the fact that something is mind-blowing indicates that it must have been created, then something must have created that creator.
Whenever I have a migraine, I put ice on my eyes or submerge my face in ice cold water, specifically my eyes. It helps so much to alleviate the pain and pressure in my head
I’ve had a detached retina numerous times and eight surgeries later I’m still blind, and that left die. A lot of your terms I’m very familiar with. I just want nothing more than to get rid of my eye to get a prosthetic because it’s so painful all the time, it distorts my vision in my good eye, and it doesn’t even look straight anymore.
Definitely interested in a video on retinal detachments please! I’ve had 5 surgeries in one eye for multiple retinal detachments, mostly caused by proliferative scar tissue formation. I’ve currently had half the retina removed and eye has been filled with silicone oil for several years now. I find the whole thing absolutely fascinating, and have watched many videos about the actual surgeries, but I’ve not seen any dissection videos about this particular subject. Thank you! 😊
When you look at anatomy that close, there’s no way anyone could possibly believe evolution. Our organs and body functionality were created by our Creator. Such precision and perfection!
Our bodies have many flaws an intelligent creator would not make. Not to mention the millions of data points supporting evolution. Let's not be poorly educated.
"And God saw every thing that he had made, and, behold, it was very good." Except of course for the approximately 350 genetic eye diseases and 10,000 whole-body genetic diseases, many of which affect newborn infants, the purest among us, and the 1 in 100,000 gene transcription error rate in each of our cells. The authors of Genesis were very wise to say "very good", not "perfect".
@@ryanw1433God created perfection but once sin entered the world, that’s when things took a turn with disease, disasters, and eventually death came about. That was never God’s plan.
@@barbarahansen8886 In the spirit of honest debate, if God is All, God is Perfect, and God created All, then how is it possible that sin disease and death could enter the world? If God’s creation is perfect, truly absolutely perfect, then how could anything evil or imperfect find even the slightest chink in God’s creation and have an effect on it? Seriously, I’m not trying to mock anything, but your theory would seem to imply an inept incompetent bumbling God, and I’m pretty sure that’s not what you intend.
This reminds me of my favourite quote from Jostein Gaarder: ‘In the eyeball there is a clash between creation and reflection. The two-way globes of sight are magical revolving doors where the creative spirit meets itself in the created spirit. The eye that surveys the universe is the universe's own eye.”
recently i watched your video on the effects of drugs on the human body, it would be very interesting to see your video on what the drugs do to the eye and how the eye interacts with the drugs and with so many variables available for this subject, i could imagine a few videos covering many drugs and alcohols and their effects on the human eye.
Our bodies have many flaws an intelligent creator would not make. Not to mention the millions of data points supporting evolution. Let's not be poorly educated.
Ok. Thank you for this explanation. I saw my optometrist just yesterday and was diagnosed with both glaucoma and "spokes" type of cataracts (along with the yellowing of the lens that comes with age). She wouldnt have even run the scan for glaucoma except that i was recently diagnosed with Ehlers-Danlos syndrome which does SO many odd things to the body. My dr talked to me briefly about what structures were effected but it was very vague and fast. This helped with my understanding as well as greatly putting to rest some of my anxiety with what i am facing in the future. I wont say im looking forward to surgery when it is time but i am more informed and have less... anxiety and panicky feelings about it. Once again, thank you for this video in particular.
He just likes to pretend he knows how the eye evolved for his gullible followers. See the vid...Evolutionists Do NOT Want You to Realize This!.....by Answers in Genesis. If those that want to laugh at it, go ahead, but your laughing does nothing to show how such a design evolved. I stay out of churches but I didn't throw my brain out because of that.
I agree whole heartedly. How can ANYONE say we were evolved? I use the eye as an example. It's too complex like a little machine. This is the first video I watched from this channel, and I am already disappointed. Shame on them. Also, the world is only 6k years old.
You guys on this thread are hilarious 😂 I was thinking the exact same thing. The eye is way way way too complex for the evolutionary process. As I’ve retired from the engineering realm of my career, I know so many scientists, engineers and doctors who have come to the same conclusions. A much higher power, a creator is responsible for our creation. A good analogy would be dissection of a cell phone and then conclude this device evolved over many millions of years from the synthesis and culmination of mineral, ore and petroleum
65 years ago, at the age of one year old, I hung myself by my eye on a cuphook. The ophthalmologist my parents took me to was not board certified and he did something that caused me to lose most of the function of my left eye. They put a patch over my "good" eye in an attempt to straighten my damaged eye, but it failed to work. I use a CPAP and because of my chronic dry issues, I suffered a torn cornea in my "good" eye. I could not do much as it healed. I have poor vision in my injured eye. It was difficult. I was recently diagnosed with age related macular degeneration. I cannot drive at night. I am so fearful of eventually losing my eyesight. I absolutely love learning from all of your educational videos. Thank you so much for the time and effort you put into all of your videos. Have you made one explaining macular degeneration? I'd be very interested in seeing that. Thank you so much.
K ya, this is 100% the coolest eyeball video I have EVER damn seen. As I watched I had questions that were promptly answered, which is also super cool. Amazing video!
Awesome, i was just trying to understand how all the process of seeing works and this video make me understand easily and the best part was the explaining of the eye evolution... amazing.
Thanks for an amazing video! I would love to hear more about cataracts and Glaucoma as my parents suffer from it. Specifically Glaucoma elevated eye pressure and why it happens in physical sense within the humor liquids intrigues me.
I’ve worked in “eye health” for over a decade. The eye is an amazing miracle. The advances we make with treatments are making leaps and bounds! I’d love to hear your guys thoughts on dry eye disease (much more dynamic than anyone thinks) and amniotic membranes being used on the ocular surface.
This was really cool to see, I did get a bit squeamish when he poked the center of the eye but I persisted until the end to learn more, it was fascinating! some see this and say "wow! isn't god amazing!" and others say "wow! look at what nature has done over the course of millions of years of evolution!" either way, you have to admit, it is a marvel to look at
Holy shit I had a dream once as a child that I have always been able to remember in which I dissected an eye and this looks EXACTLY like it, especially the lens, I remember how it looked very clearly and it was just like this. I have no idea how this is possible but am very surprised.
I had my eyes lasered some years ago and am still fascinated by the fact that a layer of my eye was basically lasered away in order to get at the layer underneath - and then it just grew back in a couple of days/weeks. The alternative is to make a cut and flip it open, but for some reason, this cut never heals completely. As opposed to removing the entire structure, which will not leave scars. Seems kind of absurd. It would be interesting to hear in more detail how that sort of thing works.

@@ChrisPBacon-ok7ir Well, if you 'knew' he meant to say cataracts then you'd also be wrong. Cataracts are clouding of the lens not the aqueous humour.
Not sure why you'd want to try to correct an Optometrist.
I work in ophthalmology and this video has helped me so much with better understanding refraction and how we perceive light! Thank you so much.
This is absolutely fascinating! As someone who’s had 5 surgeries on my eye in 5 years due to a ruptured globe. I’ve had something done to almost every part of my eye. Thank you for the awesome video explaining the parts of the eye!
WOW! Thank you, doctor. You are a natural teacher. You show bite size pieces of important information that sticks with you. More like embeds into your brain. Very much like the process of how we remember "Where were your when..." You are doing a great service to the pedestrian population who would otherwise be ignorant of the wonderful workings of our bodies.
The words "bite size" must have been a deliberate choice. 😂
A big thank you to the souls who donated their bodies, so that people would have cadavers to study
Many years ago, I had an employee that worked for me get into a surfing accident. Both his retinas slowly detached and I sadly observed him lose almost all of his vision (I am sure by now he is blind). I felt so bad, I bought him very large monitors because I noticed he kept decreasing the resolution to see better. So I would be very interested to learn more about what happened to him.
One of my coworkers, who I sit behind in the office, enlarges everything on his monitors to the point I can easily read them.
I use to watch this guy on here that's a surfer that is now blind went blind a few years ago. Maybe the same dude? He's famous ig you could say tho he does the voice overs for trailers
Who is it? @@Lord_Itachi8758
@@Lord_Itachi8758nah, in his case, he knew of his genetic disability early on and adapted as his vision slowly disappeared
I was born with congenital cataracts and had amblyopia when I was small. I'd love to see videos about these topics! Thank you for another fascinating video!
I had both of my lenses replaced and corrected my nearsightedness at the same time!
I was also born with congenital cataracts! Mine have thankfully not developed badly enough for me to require surgery at this point in my life, but I found out at age 22 when I went to the eye doctor (all by myself for the first time, my parents never really took me to the optometrist as a kid, which was fine) and the doctor told me about it and mentioned how mine are mild for someone who was born with them, but they’re there. I assumed there were other people like me but I never had the opportunity to speak with one.
There are plenty of us out here. I had mine removed at 19 and other at 25.
I’m less than 3 minutes in and this is already one of the most informative anatomy/biology videos I’ve ever seen. A++
Thank you so much for this video - very enjoyable and educational. As someone who has been living with floaters and had laser therapy for a retinal tear, I've always been obsessed with the vitreous humor and the retina. So, it'd be nice to see more details of that on the channel. 😃
I would definitely like to learn more detail about different eye conditions like glaucoma, macular degeneration, and the vision deficiencies that can develop like myopia, hyperopia. Also, I would like to better understand what happens in the optic chiasm as well. Thank you!
University of Google is at your fingertips.
@@ChrisPBacon-ok7ir Not what he's asking for though, is it...
Myopia and hyperopia are part genes and part enviroment. Myopic parents tend to have myopic kids. Macular degeneration has many diffrent types, depending on the layers of the retina, and blood vessels, not easy to explain here. glaucoma is pressure related. if your eye gets over above the healthly pressure for your eye it will slowly develop glaucoma.
@@Blaxton9Well in certain cases the environnement ends up being fully responsible for myopia development.
I became myopic only at 22-23 because of close up screen time and a new born chronic illness.
If I had good habits and not taken that medication making me sick. I would probably still see perfectly today.
That sucks and I wish we were thought how to take care of ourselves.
I can't answer that completely cause I'm DUMB but iirc (i got into this stuff like a month ago) the nerves of the optic chiasm move to the LGN of the thalamus before moving on to the primary visual cortex, and then a bunch of other complicated shit happens involving the interconnected shenanigans of the brain layers and subdivisions
Great basic eye overview! I have complicated bilateral uveitis. I’m a “special” patient. I know way more than I ever wanted to about the eye. For people who don’t know how crazy complicated our eyes are-I’ve had 5 different specialist ophthalmologists-neuro-ophthalmology, uveitis, glaucoma, retina, and cornea. To make things more interesting, the glaucoma and cornea problems I have are specific to uveitis patients. I’m at very high risk of a detached retina from the uveitis and familial history. If you ever want a patient’s perspective, lmk.
I know the feeling of being a “special patient.” I have had several retinal detachments and numerous other eye complications/surgeries. It’s scary but I’m glad I still have some vision. Thankful to all the eye specialists out there for sure.
When the two halves of the eyeball were separated, that was both amazing and disconcerting at the same time... 😳😅
11:11 is so thought provoking, and it made me think of the opposite reflective properties of things like convex mirrors that they put on lamp posts to help people see blind spots on roads. The eyes are absolutely incredible, and some are magically beautiful 😊
such a precise and complicated architecture and yet we want to label it as 'evolution' and push the supreme creator out of the picture - amazing
I have had a detatched retina in my left eye since 1990, and this is the very first time I've truly understood what a retina looks like! Many doctors have tried to explain to me what the retina looks like but I never could truly picture it. So THANK YOU for finally showing me!!! Also, I would love to see what a detached retina really looks like! Thanx!
He's holding the most sophisticated camera ever made
You took the words from my mouth. You said that correctly!
This was an eye-opening analysis 😂 love this channel. Keep up the great content ❤
Definitely would like to see more about nearsightedness and far farsightedness. BTW, I love your channel and the info you provide. Your presentation is fantastic.
As someone with both of these (Nearsightedness in one eye and farsightedness in the other) this would be AWESOME.
It’s amazing just how complex the eyes are for being such small parts of the body
I like watching these videos, because they make me learn about new things that are interesting and motivate me as a doctor
Really, you're a doctor...? 🤨
I don't think you're art is bad, I totally got what you were talking about. I could follow along and understand where you were leading us.
Truly appreciate you explaining our bodies in a way that is easy to see how and why things work like they do and the abnormalities that can happen sometimes.
His art is better than mine.
This Anatomy channel is awesome but I am really curious as to how they prepare and preserve the bodies for Anatomy classes and research.
I am curious if they could preserve the eye with the humor while it is cut in half. Maybe, replace it with some jelly just to model, wha the light has to go throug
@@RelakS__ generally I think organic fluids are a bad idea to keep in cadavers because they can rot. Maybe like you said if they replaced it with a jelly or something that would work, but I doubt the original humor would be easily preserved
This video is truly eye opening
I was waiting for this comment 😂
What an intricately constructed piece of organic instrumentation!
bro the best camera already exist, it's been around since the dawn of time! no really.
I'm very interested in a video going over acquired astigmatism and other age related degenerative changes in the eye. You explain things very well and we the curious really appreciate the work you do.
Also, thank you for your service! When you served, was it in a medical capacity? If you don't mind answering. Bio videos for you both would be interesting as well; what brought each of you to the medical arts and so on.
I wanna see more about boobies
Wow This As Really Opened My Eyes.. Big Respect To All The Men And Women Who Donate Their Bodies For Science
What's with the odd capitalization?
Yes I definitely want videos on diseases like glaucoma, cataract,myopia ,hypermetropia,astigmatism retinal detachment etc I'd love to see that please.❤
I would love to watch nearsightedness/farsightedness, retna detachments also. Love! Love the eye and other videos that I saw learned a lot. Amazing nature of eye and how it adapts to our environment. So intricate, precise and beautiful creation by Lord. Truly amazing. Thanks Jonathan
Myopia Hypermetropia and retina related problems like retinal detachment, swelling Macular degeneration etc. Would be some really good topics
I have had 2 cataract surgeries, and a vitrectomy. I also have macular edema, so I have been learning more about eyeballs than I ever thought I would need to know. The fovea is supposed to have an indent, but mine was swelling, so my vision was becoming distorted. The doctors still don't know what 's causing all this inflammation because I was tested for diabetes and I don't have it. It's a real drag because I am a graphic artist. Maybe it's because I have used my eyes so much during my lifetime looking at tiny details and staring into light-tables and stuff. I'm in my late 50s by the way. Thanks for showing us that real human eye ball!
Your inflammation is probably automimmune and not related to your eye usage, so don't blame yourself if you do.
I'd be interested in knowing more about "floaters", i.e. what they are, what produces them, and so on. Really, though, I'm fascinated by ALL your videos.
I think that floaters are supposed to be normal breakdown of the jelly in your eye, they are supposed to disappear over time, or your brain compensates.
Floaters are microscopic structures in the vitreous body. They're extremely small - can't be seen without a microscope, but they can float through certain parts of our eyes and either cast a shadow on the retina or cause light waves to flow around them and refract, therefore making them visible
It would be interesting to see if you could do one on strabismus and eye muscle problems (which I grew up with - I was also born with one near sighted and one far-sighted eye)
Dang! I can understand how contact lenses can help with that, but glasses lenses must be weird.
I really appreciate this entire channel. I'm glad you guys pushed content on TikTok because I don't think I would have found you without that
I just wanna say thanks to the person who donated their eye to make this video
We will always support this channel. You offer the best informational videos.
I appreciate learning about the human body. For me it's how amazing God created everything.
Yes!
The eyeball didn’t just evolve, it was created!
No one said it wasn’t
It was created in its complete state like we see it today in every newborn. And it for sure did not take 500k years! Every smallest detail is developed and “programmed” in the womb.
lol
Evolution of the eye makes no sense without a designer. An intelligent being has to have PLANNED it even if it did evolve. This video has further increased my belief in a Creator.
@@lindastrang8703 that creator must be a very bad designer, putting veins over the light sensitive cells. Human made cameras are designed better...
Out of all the numerous eye ball videos I’ve seen, this has to be the coolest!
Amazing... as I watch this kind of video, I start to believe some high power that created everything......think of everything.. how smart....
Uveitis. It's usually related to autoimmune disorders. I'd love a video on it! 🙂
My eye doctor said I have a form of uveitis too. Yeah, it would be great to learn more about that.
Yes! I love to see a video about uveitis and the other HLA-B27 conditions
@@avarand9601, A video on HLA-B27 would be amazing!
13:00 Fun fact because we have our cones and rods behind their blood supply(or something like that) which isn't ideal, we have a blind spot where these enter the eye and make it impossible to have photoreceptors there, cephalopods(octopus, squid,etc) have the blood supply behind their photoreceptors so they don't have a blind spot... this is also a good argument against intelligent design.
Cephalopods were created by intelligent design, by Cthulu.

I do not understand why you felt the need to involve religion here out of all places
@@Sonilotos Whoa there friend who said anything about religion, intelligent design is a theory that the universe and its complex life forms cannot be explained solely by natural causes and that there must be a being that created them, it's not my fault this just happens to be the main argument most (but by no means ALL) religions use to disprove evolution, you do not HAVE to be religious to believe in this. There are a lot of things science can't yet explain, but evolution isn't one of them.
For what it's worth science doesn't say there is no "god/higher being" there may very well be one at the very beginning of it all but it's highly unlikely he was designing individual animals when the mechanism of evolution can do it all by itself.
There's something so surreal seeing something opened up for real instead of reading it from a textbook
WOW … this video will be great for my 8 yo granddaughter ! She’s very curious and is always asking questions about how we breathe and see and hear and what the kidneys and liver and brain and so forth , look like and function . So thank you for making this wonderful video ! I just hope she doesn’t start asking about synapses and neuron’s ! She watched a movie a couple of months ago and then asked me “ What does it mean when the pupils are fixed and dilated ? “ Geez !!! 👍👍👍❤️❤️❤️⭐️⭐️⭐️⭐️⭐️😊😊😊
This is truly one of the best videos I've ever come across on any platform.
The creation and designs of each and everything is Spectacular and Mind-blowing. Our creator Is soo advanced!
If mind-blowing stuff is indicative of a creator, then who created that mind-blowing creator?
@@kellymichelley Your question is like Who created Your Spirit.
I'm just insinuating that if the fact that something is mind-blowing indicates that it must have been created, then something must have created that creator.
In other words, either something created the creator, or there is no creator at all.
@@kellymichelley yes creators will created him.
Cooling the eyes is quickest way to cool the brain
Whenever I have a migraine, I put ice on my eyes or submerge my face in ice cold water, specifically my eyes. It helps so much to alleviate the pain and pressure in my head
I’ve had a detached retina numerous times and eight surgeries later I’m still blind, and that left die. A lot of your terms I’m very familiar with. I just want nothing more than to get rid of my eye to get a prosthetic because it’s so painful all the time, it distorts my vision in my good eye, and it doesn’t even look straight anymore.
Here I am again, so intrigued and learning about an eyeball without anyone forcing me
Definitely interested in a video on retinal detachments please! I’ve had 5 surgeries in one eye for multiple retinal detachments, mostly caused by proliferative scar tissue formation. I’ve currently had half the retina removed and eye has been filled with silicone oil for several years now. I find the whole thing absolutely fascinating, and have watched many videos about the actual surgeries, but I’ve not seen any dissection videos about this particular subject. Thank you! 😊
When you look at anatomy that close, there’s no way anyone could possibly believe evolution. Our organs and body functionality were created by our Creator. Such precision and perfection!
The Lord is amazing indeed!!🙌🦾
Our bodies have many flaws an intelligent creator would not make. Not to mention the millions of data points supporting evolution. Let's not be poorly educated.
"And God saw every thing that he had made, and, behold, it was very good." Except of course for the approximately 350 genetic eye diseases and 10,000 whole-body genetic diseases, many of which affect newborn infants, the purest among us, and the 1 in 100,000 gene transcription error rate in each of our cells. The authors of Genesis were very wise to say "very good", not "perfect".
@@ryanw1433God created perfection but once sin entered the world, that’s when things took a turn with disease, disasters, and eventually death came about. That was never God’s plan.
@@barbarahansen8886 In the spirit of honest debate, if God is All, God is Perfect, and God created All, then how is it possible that sin disease and death could enter the world? If God’s creation is perfect, truly absolutely perfect, then how could anything evil or imperfect find even the slightest chink in God’s creation and have an effect on it? Seriously, I’m not trying to mock anything, but your theory would seem to imply an inept incompetent bumbling God, and I’m pretty sure that’s not what you intend.
Give my eye back.
Athiest be like : yea it evolved on its own
Anyone who doesn't understand that, must not realize the incredible, incomprehensible amount of time it took for that to happen.
This reminds me of my favourite quote from Jostein Gaarder: ‘In the eyeball there is a clash between creation and reflection. The two-way globes of sight are magical revolving doors where the creative spirit meets itself in the created spirit. The eye that surveys the universe is the universe's own eye.”
recently i watched your video on the effects of drugs on the human body, it would be very interesting to see your video on what the drugs do to the eye and how the eye interacts with the drugs and with so many variables available for this subject, i could imagine a few videos covering many drugs and alcohols and their effects on the human eye.
God is a maker of complicated miracles.
Oooo looks squishy.
It looks like it would taste like a brussel sprout.
God’s creation is awesome and complex. We are wonderfully made.
Our bodies have many flaws an intelligent creator would not make. Not to mention the millions of data points supporting evolution. Let's not be poorly educated.
Proof of God?
Don't take the bait...😂
The eye and hand "Designed " beautiful and complex thank you guys.
Ok. Thank you for this explanation. I saw my optometrist just yesterday and was diagnosed with both glaucoma and "spokes" type of cataracts (along with the yellowing of the lens that comes with age). She wouldnt have even run the scan for glaucoma except that i was recently diagnosed with Ehlers-Danlos syndrome which does SO many odd things to the body. My dr talked to me briefly about what structures were effected but it was very vague and fast. This helped with my understanding as well as greatly putting to rest some of my anxiety with what i am facing in the future. I wont say im looking forward to surgery when it is time but i am more informed and have less... anxiety and panicky feelings about it.
Once again, thank you for this video in particular.
oh this is going to be hard to watch.
God is so amazing
Yes very Amazing ❤
Far too complex to have "evolved". The incredible complexity you have demonstrated can only be attributed to a creator.
He just likes to pretend he knows how the eye evolved for his gullible followers. See the vid...Evolutionists Do NOT Want You to Realize This!.....by Answers in Genesis. If those that want to laugh at it, go ahead, but your laughing does nothing to show how such a design evolved. I stay out of churches but I didn't throw my brain out because of that.
I agree whole heartedly. How can ANYONE say we were evolved? I use the eye as an example. It's too complex like a little machine. This is the first video I watched from this channel, and I am already disappointed. Shame on them. Also, the world is only 6k years old.
You guys on this thread are hilarious 😂
I was thinking the exact same thing. The eye is way way way too complex for the evolutionary process.
As I’ve retired from the engineering realm of my career, I know so many scientists, engineers and doctors who have come to the same conclusions. A much higher power, a creator is responsible for our creation.
A good analogy would be dissection of a cell phone and then conclude this device evolved over many millions of years from the synthesis and culmination of mineral, ore and petroleum
Think of all that eye has seen!
65 years ago, at the age of one year old, I hung myself by my eye on a cuphook.
The ophthalmologist my parents took me to was not board certified and he did something that caused me to lose most of the function of my left eye. They put a patch over my "good" eye in an attempt to straighten my damaged eye, but it failed to work.
I use a CPAP and because of my chronic dry issues, I suffered a torn cornea in my "good" eye. I could not do much as it healed. I have poor vision in my injured eye. It was difficult.
I was recently diagnosed with age related macular degeneration. I cannot drive at night. I am so fearful of eventually losing my eyesight.
I absolutely love learning from all of your educational videos. Thank you so much for the time and effort you put into all of your videos.
Have you made one explaining macular degeneration? I'd be very interested in seeing that.
Thank you so much.
K ya, this is 100% the coolest eyeball video I have EVER damn seen. As I watched I had questions that were promptly answered, which is also super cool. Amazing video!
the eye didn't evolve it was created by God
Grow up..
Grow up
Awesome, i was just trying to understand how all the process of seeing works and this video make me understand easily and the best part was the explaining of the eye evolution... amazing.
I need all those things to watch this video. A human camera! Amazing!!!
Thanks for an amazing video! I would love to hear more about cataracts and Glaucoma as my parents suffer from it. Specifically Glaucoma elevated eye pressure and why it happens in physical sense within the humor liquids intrigues me.
Wow, this is such an eye opener
13:15. Either the best unintentional pun ever, or too cool to make a big deal about it. Either way, amazing video! 👁️
I’ve worked in “eye health” for over a decade. The eye is an amazing miracle. The advances we make with treatments are making leaps and bounds! I’d love to hear your guys thoughts on dry eye disease (much more dynamic than anyone thinks) and amniotic membranes being used on the ocular surface.
That’s so freaking amazing - also reminded me of high school and dissecting bulls eyes!!
Would love to learn more about astigmatisms please. My husband has them!
I myself are affected from makula degeneration (Morbus Stargardt). Id loved to see a Video about That!❤
Looks intelligently and intricately designed.
There's waste disposal less than a foot from a recreational area, choking is too easy and we get back pain from walking, that's not intelligent at all
This was really cool to see, I did get a bit squeamish when he poked the center of the eye but I persisted until the end to learn more, it was fascinating! some see this and say "wow! isn't god amazing!" and others say "wow! look at what nature has done over the course of millions of years of evolution!" either way, you have to admit, it is a marvel to look at
Holy shit I had a dream once as a child that I have always been able to remember in which I dissected an eye and this looks EXACTLY like it, especially the lens, I remember how it looked very clearly and it was just like this. I have no idea how this is possible but am very surprised.
I had my eyes lasered some years ago and am still fascinated by the fact that a layer of my eye was basically lasered away in order to get at the layer underneath - and then it just grew back in a couple of days/weeks.
The alternative is to make a cut and flip it open, but for some reason, this cut never heals completely. As opposed to removing the entire structure, which will not leave scars. Seems kind of absurd.
It would be interesting to hear in more detail how that sort of thing works.
Fascinating as always! ❤️
I want to take a moment to thank the person who's eye just helped us gain a better vision. Thank you eye person, may you rest in peace.
My ICU RN brain can't help but think of all the tears that came from that I and all the joy and pain at saw, it's our own little video camera of our life. Too bad you can't just click away when you want to
It's such an eye-popping experience that this was. I see why it's interesting to watch.
Yeah, please do more eye topics! This was interesting.
*This was actually an eye opening video* 👁️👁️
Amazing stuff, as always, on this channel. Better yet, the host(s), while SMART AF, always manage to explain things in a way most anyone can understand.
This is fascinating! I didn't realize the fibrous tunic was that thick.
I love this channels videos, they are so easy to understand and very interesting to watch!
For some reason I was expecting the FBI to break in, shoot everywhere, cuff him and then radio in "we've got him! We finally got the eye-thief serial killer!"
😂😂😂
Amazing video by the way.
This was a great explanation of how the eye developed and works. Thank you!
