How do glasses help us see? - Andrew Bastawrous and Clare Gilbert

View full lesson: ed.ted.com/less...
Today, glasses help millions of people with poor vision be able to see clearly. But how? Andrew Bastawrous and Clare Gilbert help unravel the answer by explaining refraction - the ability of a transparent medium, like glass, water, or the eye, to change the direction of light passing through it.
Lesson by Andrew Bastawrous and Clare Gilbert, animation by Andrew Foerster.

I have myopia and have glasses but only like to use them in class or to watch a movie. But on the odd occasion that I forget to take them off after class and go outside with them on, I get this crazy moment where I realize how detailed the world really is, like HOLY COW I can see individual leaves on a tree. WHOA! Usually when I have these moments my friends think I've gone mad cuz I started examine random objects like they contain the secrets to the universe XD

Has anyone been asked "can you still see things, without glasses/contacts?" that is they're asking it as if without seeing aid we're completely blind? I have had to a few times explain that poor eyesight doesn't equal blind, but rather blurry vision.

[@DecoyBlackMage]

+ArtisticAsian1014 At the same time, being blind does not equal a person being unable to see anything at all, complete blindness is overall rare. Though those who do have pretty negative stats on their vision without glasses can be labled as blind to an extent if I recall correctly. Then we have double vision (( I suffer from this at times, nerve damage )) which can require prisms to correct if permanent or until your brain creates a new auto correct which could take 3-8 months. So to an extent yes really poor eyesight can label you as blind from a medical standpoint anyways.

[@ArtisticAsian1014]

DecoyBlackMage Interesting. I've heard of double vision but not much on it. I'm assuming the nerve your talking about is the optic nerve? You do have a point though; extremely poor vision can be labeled as blind to an extent. I guess in my case, I just don't like how the people who have asked me in the past (tone and wording of sentence).

[@DecoyBlackMage]

ArtisticAsian1014 Yes and no, I suffer from MS so yes to an extent the optic nerve can be damaged. But in my case I have had scars forming in my cerebellum a couple of times, which has damaged my brains ability to put images together, the brain requires time to create a new setup but generally double vision is not permanent. Eye damage is one thing but we can also gain vision problems if damage happens to the optic nerve or cerebellum, and the results can be quite weird at times.

[@solum_mirari5925]

I guess he's referring to people like me who once they drop their phone without contacts can't find it until they either step on it or put contacts in.

[@iksroney]

I'm not really blind. I'm almost completely blind though. In my left eye. It's basically useless, and sometimes it just wonders off. Looking at something random. My right eye is looking straight ahead, when my left eye is looking somewhere to the left, right, up at, down, whatever. Some think I'm cross eyed. But are my eyes crossed? No! They're just looking in different directions..

Just got my glasses a few months ago. I can still remember way back then, i thought that the world was seen that way. I thought it's normal to not clearly see objects beyond 5 meters from me. But when i learned about glasses and eventually had one, i can still remember how teary my eyes were as i was then able to clearly see every object and the leaves of the tree and the people passing by. It was my fist time to appreciate how beautiful the world where you can see even the very detail of an object. Right now, i still have it as i write this, and i am grateful as it really helped me in various ways. (Sorry for my English) Cheers to all who has myopia and astigmatism. ♥️

I'm super near sighted. When I was young I was fascinated by nature photography because of the intense detail that I thought could only be picked up by cameras. When I finally got my glasses, I was near tears because I realized that that was what the world was made up of all around me. I didn't realize that other people saw trees that way all the time and I drew them over and over again for a while. Before glasses, it was silhouettes that I loved. After, it was detail. PS: Does anyone else take their glasses off to eat?

Always nice when everyone tells you you need x only to have it turn out you really don't.

[@krisizcelja]

The first time I put on my glasses a year ago (at the time), I was like" 'GASP' THERE ARE LEAVES, I SEE DETAILS ON CLOUDS, EVERYTHING LOOKS SO MUCH COOLER!!", until I brought them to school, and I felt so awkward, knowing that I just came to school with FREAKING GLASSES. I got over it :). Oh and I can still see things far away, it's not a bad myopia. I can go to water parks, going to the beach, riding a roller coaster, anything you're not supposed to bring with you.

The ending reminds me of the time I got glasses for the first time and was commenting on EVERYTHING I saw. I had a field trip to the zoo the next day and my dad told me, "You might see some animals you had no idea existed. There's a brand new world for you to discover."

[@ramennoodles2589]

When I was really young like 3-7 I had pretty good vision but then as my eye grew my eyes were shaped kind of like a rugby ball so I had to get glasses because I was short sighted. I stopped wearing my glasses because I thought I didn't need them and then next time I went to the optician at 11 my right eye was still short sighted and my left eye was long sighted. They told me I should wear my glasses more often because it could help my vision. So even if you don't feel like you need your glasses on please just wear your glasses once you get them often because it can really help.

[@cellostrings565]

You never really know how bad your vision is until you put glasses on

[@azure9886]

[@excessvoltage]

do animals experience same eye problems as humans do ? why so many people in the world, like 400 million, have bad vision ? why our eyes are so prone to work so bad , while we don't have any deterioration problems with our other senses ? how can you explain bad vision with evolution ? Aren't genes that cause bad vision suppose to disappear and if so why it's still so prevalent ? I wish you could answer these questions too .

[@thefinnbomb8321]

+excessvoltage That's not how evolution works. Bad genes don't just 'disappear'.

[@excessvoltage]

@114757710086722053084 but they certainly diminish in number. what I aimed to understand is why eye problems are more common than say, nerve problems that effect touch or nasal problems that greatly reduces your ability to smell. Why our eyes more prone to detoriate 'compared' to our other senses

[@excessvoltage]

just found out the answer to this question. the cells in our eyes never regenerate or replicate, contrary to other cells in our bodies. Another example are the cells in our ears which aid hearing. So as we grow older we lose our hearing and vision the most because the cells there start to die and new ones can not be produced.

[@qwertyuiopasdfghjkl9879]

"Waiting to reveal a whole new world that's hiding in plain view" Wow I love it! I'm going to put my glasses on right now

[@marthastawska9237]

My vision used to be -10. Then I got laser. 🙌🏻 literally life changing

[@Nah_no_cap]

I got my glasses almost 2 years ago and I had very minor myopia back then but recently got diagnosed with astigmatism and the situation of my eyes are getting worse and I've been kinda stressed about it given the fact that the eye condition gets worse day by day. Times like this I feel like why me? No other kids in my class wears glasses and can see the board perfectly even if sitting in the last bench but I can't see it clearly even when I'm not in the last bench. I sometimes feel really bad for being so weak and think what's gonna happen when I'm older

[@oliviabakers8852]

Same, I got my glasses when I was 5 and I wasn't able to see the TV or things in front of me very well back then. Nowadays I need my - 12 prescription thick glasses to be able to see anything. I'm 15 and nobody else in my class needs glasses and then there's me who can't see anything without mine

[@youawake6961]

They also mess up your eyes :////

[@thegamerswitch109]

do they? EXPLAIN!

[@gregavrhovnik1155]

+TGS Gaming Videos (TheGamerSwitch) Using glasses every day for a few years might decrease your vision.

[@thegamerswitch109]

+Grega Vrhovnik omg thanks this helps no lie now I know why my eyes getting bad for no reason

[@thegamerswitch109]

I wear glasses, yet see fine without them. Supposedly I have them to help with headaches I used to occasionally get when reading, looking at screens, etc.

[@wadduck67]

[READ IF YOU CARE FOR A MYOPIC CHILD] I am Myopic but my glasses are doing nothing!Even when I get new ones they still do nothing and I am hoping that in the future something will help me,it seems that every second my rage of sight (my sight of seeing stuff not blurry)is ever so slightly getting closer and closer to my face and soon I may have fully blurry vision.This is making me have a bad time at school seeing the white board so I have to sit closer and closer to it.

[@inmybrainpodcast]

*true story* me with my glasses off: hey have you seen my glasses? them: bro they're right there me: where? them: BRO CAN YOU NOT SEE? me: no... i cannot see

[@prof.einsteindarcy3951]

AMAZING ANIMATION GUYS!!!

[@tasneemfahoum5931]

Great job TED!

[@freefiredesilover5079]

When me doctor put correct glasses on my eyes Me to myself : What I was seeing from 15 years. Everything is hd now😂but without it blurry.

[@MusaonYT]

Loved the animations!

[@MusicalGirl2311]

As someone who has been nearsighted for about half of my life, seeing the perspective of a farsighted person in this video is bizarre. I’ve always known what it means to be farsighted, but to actually see it is like having my vision inverted.

[@ieatalgae]

YEAH EXACTLY

[@badsuperhero6943]

Can anyone else make their eyes out of focus whenever you want? I don't have glasses, which is weird because literally everyone in my family has glasses.

[@alexissong3540]

This makes me feel like I'm not alone.

[@megadethmaniac]

I don’t know why I’m watching this, im 11 and i was diagnosed with myopic so I’m gonna need permanent glasses i tough time I was the only one but then I saw 1:47

[@kerentan9446]

i go through a pair of glasses about every two years, so i'm hoping i can donate the frames to people about my age who need them.

[@vocaloidlenrin]

*Before glasses* I see pretty good, I don't need them *puts on glasses* WOW 4K vision ,cool man *removes glasses* I am blind !!

[@YouTube-Autotech]

I am myopic and I was myopic since I was small but I didn't knew that. I thought that humans can see only this much as I can. So during a random eye checkup I couldn't see anything after the first big 🔠. I directly went from no glasses to glasses with -2 power. And god I couldn't believe that how was I able to see so much details. And now after 4 Years I have -5 as my number. Blind AF without glasses like I cannot even see read a book kept 25 cm away. Thank God I have glasses now otherwise life would be very difficult.

[@newbie4789]

I think everyone here who got glasses at a younger age might have that "wow" moment of seeing things clearly for the first time ... Like "Omg I can see the leaves of a tree now?"🤣🤣🤣

[@goatlps]

Q. So, if glasses only correct refraction errors, if you have 'perfect' vision glasses can't improve vision? Or is there no such thing as perfect vision/refraction, so glasses could correct a tiny error?

[@goatlps]

...Not including using binoculars, obs, just glasses LOL. Internet says the best recorded human eyesight is 20/10 (at 20ft you can clearly see what a person with 20/20 vision can clearly see at 10ft) - but Internet didn't say if that person was wearing glasses or not.

[@shibegameing501]

When you put your glasses on for the first time you'd like: "This is how life is supposed to looks?"

[@alisonbee3861]

I got damaged my cornea so I have classes and you can also get glasses by damage in a part of your eye

[@gimlee44222]

this video is wrong myopia and hyperopia mean the eyeball is either too long or too short which is why the light isn't focused retina NOT because of curvature of cornea

[@Fireneedsair]

The shape of the cornea causes astigmatism
