    idk about u noobs in the comments talking about just alright eye sight without glasses and how they make ur eyes worse and you can fix ur eyes w exercise but i have literally had this horrid vision since i first went to the eye doctor when i was 6. I didn't know that my vision was a problem and I thought not being able to see perfectly was normal so when i went my eyesight was terrible just naturally. I have never met anyone who needs as high of a prescription glasses as me. So honestly screw all you people hating on glasses and saying you can fix your eyes, because sometimes you just have to have them to see or you wouldn't be able to live normally.

    Are you sure about all of this? I'm 40 and I just asked a very reputable eye doctor the exact same thing, and he paused, and said that yes it's true. To clarify, I'm 40 and have never worn glasses before, and asked him if starting regularly would put more strain on my eyes. Even at a correct prescription.

    I just know that my vision kept getting worse at a pretty crazy rate while wearing glasses and slowed down when I went to contacts. There are likely other factors, though.

    I got it, totally understand why one needs to wear glasses if far or near sighted…you definitely explained the eyeball well. But how does the eyeball function for those of us that wear bi-focals, we’re blind without our glass for reading  or anything close, and we’re blind for driving, especially reading signs and seeing objects, like people or dogs coming at you. But we can see say if you are 2-3 feet in front of me just fine, no glasses required, well unless it’s dark, then I can’t see anything!

    As a child I used glasses from ages 10 to 16 and then one day I just stopped. It affected me for the first couple weeks of months and then my vision felt focused and normal after a while so I did not go for a replacement. I did a eye exam for my exam at age 19 and my results showed that my vision was 20/20. I am now 32 and I have been doing an eye examination, as a part of my annual medical check-ups, for the past 8 years and my vision still remains perfect. Can you explain what happened in my case? Just curious. Ps: I was teased a lot by one specific person for wearing it as a child.

    Me and my brothers have a rare eye condition and we have been going to mcmaster hospital and other special optometry places who teach and train new students to do eye tests for over 19 years well sometimes we would go 3 or 4 times a year we didnt know what we had so they were trying to figure it out and we noticed changes me and my older brother did anyway in years we went to see the docters 4 times by the end of the year our prescriptions would change drasticly as compared to years where we only went once or twice this was just in our heads thoe we didnt have any actual paper work to prove it. And my question is can all these eye docters who arnt professionals actually be ruining our eye sight because every single time we get sat down in a chair look straight ahead and they shine a bright light directly in our eyes and even use magnifing lenses to see the back of our eyes more clearly and were asked not to blink for a full 3 minutes or longer per eye as they do this (they are students so it does take them longer), everytime we went it was like this and even multiple times a trip alot of the time they gave us eye drops to fully dilate our eyes so even more light could get in and really me my brother and my parents all think now that that might be the reason we are as blind as we are and they might as well have shone lazer pointers in our eyes or made us look at the sun for 2 minutes a visit. So could this be the reason why our eye sight is so bad we are registered as legally blind.

    What happens if I had one nearsighted eye and one farsighted eye?

  • multiplyx100

    My first glasses really hurt my eyes for a long time until I realised that the orientation of the lenses makes a huge difference. By twisting them round in various dimensions the glasses no longer hurt my eyes. I am astigmatic, but it's possible this might work on all glasses equally. You can flex your glasses from side to side, and then up and down (each side in the opposite direction), and see if your eyes feel more comfortable as you do it. This will move the centre of the lens, and therefore has the effect of changing the direction that your eyes are pointing in. If you are astigmatic you will also need to rotate each lens along the axis of your line of sight to find the optimal orientation to give you maximum focus. It might not be the same on each side, and it could vary over time.

    I havent been able to afford new glasses for more than ten years. Went to an eye doctor a year ago and he said the vision in one eye had gotten better. Didn't get new glasses cause they were do damn expensive. Apparently, i wasn't elegible for their $79 special. Instead it would cost over $400. So i am still wearing the same glasses. Can't read with the bifocal part of the glasses so i have to take them off for close up stuff, and i can't see clear at a distance with the distance part of the glasses but can see distant stuff through the bifocal part. That's just weird.

    "Too much reading and close work at the screen tires the eyes and can lead to shortsightedness." Alliance Optikk. Sorry, but it's actually mainstream and official. Weak eye muscles certainly do lead to vision problems, so you're also wrong there.

    As a woman, I truly hate my glasses. My hair gets caught in them anytime the wind picks up. Driving with the window down is nearly impossible to do. I can't snuggle while watching a movie because this action causes my glasses to move and the movie I'm trying to watch becomes impossible to see. I need two pairs of glasses just to make sure I don't go without one, in case I forget or break one at any given day or time. If I could afford it, I'd get corrective eye surgery and be done with it all!..😆

  • Hubertdtu

    I understand that you need reading glasses when you get older because the lenses are getting stiffer, but in my case, in addition to the increased correction needed for reading, I also need an stronger correction to see in the distance than in previous years. Where does this second effect come from?

    Before I got my glasses I didn't think I needed them, I could read stuff far away just fine. Ever since I begun wearing them if I take them off I'm blind as a bat, I wish I could have just never gotten them because now I'm stuck with glasses forever. After your eyes adjust there's no going back, they are gonna be worse then before.

    although, with people thinking that glasses make your sight worse, it might be due to you being used to the blurriness before getting them, but then after, you tend to notice it more. "was my sight really this bad?! holy cow!"

    The reason I clicked on this video is because I've noticed that since I started wearing glasses my general eyesight without them has gotten much worse. I did't even go to an optometrist for my eyesight, I went because I had scratched my eye lens months earlier and was still experiencing a weird sensation. But after examining me and finding nothing wrong as far as the scratch goes he handed me a prescription because I kinda do need glasses, mostly for driving at night. So I filled it and started wearing them for night driving. But as I've had them for two years now I've become dependent on them to keep things in focus, even during the day. I can absolutely believe that they make your eyesight worse, at least worse faster that what they would've without the glasses... I'd like to point out that I'm not trying to denigrate glasses. Just that from a subjective perspective I can understand how it's possible for glasses to worsen you unaided eyesight.

    "The only effect they may have on your eye muscles is reducing excessive strain on them" If you are myopic your eyes suffer from OVERLY EXCESSIVE EYE STRAIN - glasses expand the rays of light causing the image to appear closer to the eye the closer an object to your eyes the more strain they are put through to let you see a crisp image so wearing - glasses WILL cause eye strain and will worsen your eyesight if you are using them from close

That's a whole different story and specifically has to do with stiffening lens muscles. Have studies been done on these folks to determine the efficacy of eye glasses over time? I'd love to know the answer to this as it directly affects me. TY in advance. :). 🤓

    Hank, why is my vision so bad? Every year for 55 yrs since I was in the third grade ( you do the math) they have gotten more and more near sighted where I have had to change Rx yearly and can only see clearly about 6 inches in front of me now. I wear trifocals. If I misplace my glasses I have to have a 2nd pair stored in a specific place in the house at all times for emergency back up to find them.! some say to wear them less to force my eyes to adjust back little by little, like wearing orthodontic braces to realign teeth. Any truth to the myth? can you improve your vision by doing less close work like reading and computers?
