benkei Posted October 16, 2008 Share Posted October 16, 2008 Does anyone know how glasses affect your vision? I mean in the long term. I theorise that your eyes would become dependant on the lenses for clear vision, therefore your eyes will never become strong enough to see clearly without the lenses. But one of my friends said that the lenses force your eyes to see clearer, so they will one day get strong enough not to rely on lenses. Your vision does however change over time, as you need eye tests and up-to-date prescriptions to see clearly. Does anyone have knowledge in this area?

DaveK Posted October 16, 2008 Share Posted October 16, 2008 Doesn't it depend on age? I'm sure I had glasses when I was a kid and now have 20/20 vision. But I don't think most adults suddenly find they don't need glasses anymore - and I think the whole point is your eyes are dependent on the glasses - that's why you're wearing them in the first place.

supra_aero Posted October 16, 2008 Share Posted October 16, 2008 More or less, if you are short sighted you must tense or contract certain muscles in the eye more than normal to see clearly. Probably caused in cases like mine by staring at a pc screen 9-5 or something which is relatively close up, which has caused these muscles to unnaturally tense up longer periods of time than normal. This is why they recommend breaks and focusing on something far away every so many minutes When you wear glasses as a result of your short sighted vision, these muscle will be slightly more relaxed than had you not been wearing glasses, BUT bear in mind it will still be somewhat tensed up as you are now short sighted. Over years naturally then these muscles become dependant on glasses and lose their tension due to the strain of being tensed over time. As they become too weaker you will eventually not even be able to contract these muscles as well at all (meaning you become shorter and shorter sighted) eventually these muscles will be so weak you they will become too relaxed rather than contract at all making you long sighted when you are older. I think its more or less something like that. Friend of optician told me this. Quote Link to comment Share on other sites More sharing options...
Vicky Posted October 16, 2008 Share Posted October 16, 2008 As a child i had to wear glasses, when i got into my teens i hated them so used to take them off at times. My eyes actually improved and got stronger because they were not dependant on the glasses. Now i dont need glasses at all Quote Link to comment Share on other sites More sharing options...
Havard Posted October 16, 2008 Share Posted October 16, 2008 I have worn contact lenses since I was 23. I am now nearly 34 and I can't see sh!t without my lenses or glasses. I feel my vision has suffered as a result of having corrected eyesight but it wasn't good to start with so hey ho!! H. Quote Link to comment Share on other sites More sharing options...

I did find after hating wearing mine my eyesight improved too when I was at uni. But working in an office I cant get by without them staring at screens all day.

But working in an office I cant get by without them staring at screens all day. exactly that, your eyes go wrong due to constant wear. concentrating on books and computers slowly messes your eyes up. wearing contacts and glasses simpy aid your vision. your eyes gradually to get weaker over age. there is laser eye surgery but a friend of mine had it done and then went back to education, his eye sight messed up all over again, back to contacts for him.

Kopite Posted October 16, 2008 Share Posted October 16, 2008 Glasses only make your eyes worse if you're wearing a prescription that's not needed when you're a child less than about 8 or so. Computers don't make your eyes worse in reality either - there's been arguments that a child looking up close all day (albeit a VDU or a book or their hand) can have their eye's growth shift to near focus more (inducing short sightedness) as their growing body "thinks" that all the world is at 40cm. Short sightedness increases as your body grows which is why it's usually teens who get short sighted. You get more reliant on specs then also as you notice the blur more when it's been corrected, some people don't realise how blurred they are. You lose accommodation with age (people in their mid 40s+ who need reading glasses) so yes you get more dependent on those glasses but you'd find your eyes get worse equally quickly even if you weren't wearing them at that age group. Everything else is pure boll*cks P.S. With short sighted people, the last thing their eye muscles will do is contract to focus - this makes short sightedness worse so it'd never happen for long distance Quote Link to comment Share on other sites More sharing options...

KamaSupra Posted October 16, 2008 Share Posted October 16, 2008 My left eye was weaker than my right eye when I was young. So I had to wear glasses from about age 9-13yrs to strengthen my left eye. The glasses helped my left eye improve and I haven't worn glasses since Quote Link to comment Share on other sites More sharing options...

The glasses helped my left eye improve and I haven't worn glasses since Around that age is known as the plastic period of your vision - pretty much where the "wiring" for your eyes is being formed. It was generally classed as being "fixed" after 8-9 years old but it does vary from kid to kid. The specs did you well in making sure your brain knew it had a left eye Did they patch you or just give you glasses? It's for a similar reason that specs can make your eyes worse at that age - if you brain isn't getting clear images during the plastic period then the wiring for that eye isn't as good as it should be; wearing the wrong glasses could do this for example.

benkei Posted October 16, 2008 Author Share Posted October 16, 2008 Ahhh, this is a little clearer now! See, I've worn glasses since I was 4 or 5, mainly due to a squint (my right eye was facing inwards and I had an operation to point it forward) so dureing the time in which my eye was pointing inwards, my vision was adjusting itself to look straight through my left eye, and out of the right side of my right eye - which would be straight ahead. My vision through my left eye isn't too bad, but my right eye is awful! Now since I've had glasses now for around 20 years, where does that leave me? I've had eye patches when I was a kid to cover my left eye to strengthen up my right eye, but I feel it's all been in vain as it's getting lazier. I recently had an eye test and told them that my right eye isn't pulling it's weight and I'm getting more eye-strain and headaches than normal. They tell me it's because my eyes have changed and I need a new prescription. But have my eyes changed for the better, or are they getting worse, ie: more dependant on lenses? When I did kickboxing, I obviously couldn't wear my glasses then, and contact lenses just don't do it for me, so did that time away from my specs help my vision improve, or just confuse my brain as my vision was constantly changing due to taking off my specs and putting them on and taking them off, etc.. I've been thinking of lazer surgery, but is it a waste of time as my eyes are f00ked? And also, reading what some of you have said, it'll just get worse again due to computer screens, books, reading, etc. Quote Link to comment Share on other sites More sharing options...

No patch they just gave me glasses, with the left lense stronger or weaker than the right side. In order to make my left eye work harder and make the muscle work properly or something. Think they said my left eye's muscle was weaker. Was years ago now so hard to remember completly as 24yrs old now. Quote Link to comment Share on other sites More sharing options...
Mike Posted October 16, 2008 Share Posted October 16, 2008 I have worn contact lenses since I was 23. I am now nearly 34 and I can't see sh!t without my lenses or glasses. I feel my vision has suffered as a result of having corrected eyesight but it wasn't good to start with so hey ho!! H. I hear you... the same predicament at the same ages. Dude, we're old It's a slippery slope when you start with glasses. Isn't there some 'natural eye correction program' you should do to strengthen them? Why don't opticians get you to do exercises without your glasses to make them stronger? Well for obvious reasons of hard currency, but...

benkei Posted October 17, 2008 Author Share Posted October 17, 2008 I've recently started excerising my eyes. I hold my hand up about 6" infront of my face and focus on it, then focus on the background which is firther away, and keep changing focus between the two. In theory this will strengthen up my eye's focusing ability and improve my vision over time. Has anyone tried that 'Eye Training' on the DS? That should help too I imagine...
