Supra Size Me Posted July 28, 2008 Share Posted July 28, 2008 This is a just from a personal experience only side of things and Kopite or others would be able to explain it better than I ever could, but is there a chance your left eye has gone slightly Toric ? the description you gave is just like what happened to me a couple of years ago. My left eye developed a ghosting and got the aches etc so went to my optician and he ran the tests etc and found that it had mis-shaped and was causing the trouble, the reason I mention this is that my prescription in that eye got slightly better from a -2 to a -1.75. I'm just wondering if at lower numbers the effects may be increased and hence the jump in difference that you mentioned. Can Kopite explain it better than I can please ?

Swampy442 Posted July 28, 2008 Share Posted July 28, 2008 I was gonna suggest what Suprasize said, maybe its something 'mechanical' in the eye itself thats changed, distorting the lense and improving your sight. A pressure build up or or reduction? Im no optician or doctor but it does sound possible if the change was so sudden. Quote Link to comment Share on other sites More sharing options...
Ian C Posted July 28, 2008 Author Share Posted July 28, 2008 Well they did the full lot of tests, peripheral is OK, eyeball pressure is OK, back of the eye is perfectly fine... just the prescription has changed I assume "toricness" is something they check for with all that? -Ian Quote Link to comment Share on other sites More sharing options...
Jake Posted July 30, 2008 Share Posted July 30, 2008 Lowering myopia is an associated sign of impotence, does happen... Anyway, there's a couple of things it could be. As Max said, there's 2 ways of writing a prescription, can you copy down your current and previous ones? First up, how old are you Ian? When people approach their late 30s, you lose the ability to accommodate (which is when the lens in your eye is squashed by your eye muscles, becomes more convex and focuses for near). I'm pretty sure you're not over 35 so what's probably happened is that your LE might have been overminused at some point (which is very easy to do as people soak up more short sighted power as your eye muscles can accommodate for distance in that point and make up for it. A lot of people think this is sharper as things look bolder, it's the same as looking through binoculars the wrong way round, things stand out more). A lot of people like being over minused for distance as it makes you artificially longsighted so your driving vision etc would be superb... but it makes you more prone to headaches and blurriness with near tasks as your eye is accommodating for distance as well as near. The more close up stuff you do the more it will test your accommodation, it'll give up at some point if you're overminused. You might have happily been accommodating thus far but maybe not toleraing it as much now. Have you been doing a lot more hours of near work? Whether it's VDUs, reading, wiring etc? The other thing it could be is this, but this is more if you're in your late 30s. Short sighted people's prescriptions do get better with age when you're pushing the 30s/early 40s bracket. Your intraocular lens loses elasticity at that time (so you lose you accommodation which is when people need reading glasses, happens to EVERYONE). Someone with no prescription or a long sighted will need reading glasses, a short sighted person will find reading up close with their glasses (or contacts in) more difficult and have to remove them for close tasks. As the lens loses elasticity, it loses it's tonus as well so the over all strength drops.. the result is you get more longsighted with age so you could drop from a -4.75 to a -4.00. It wouldn't have been overnight as such, you might just be noticing it now. This would do the same thing as if you were overminused as above, you'd be trying to accommodate more - the ache over your eye is usually your eye muscles aching. The other option is a lot more simple... you could have slept with your eye in a funny place (oo-er) and changed the shape of it somehow. Usually when this happens, it's your cornea but you'd have some kind of sensation there normally. Did you get any new specs ordered? Will be interesting to see if it stays as -4.00. Normally, muscle strain etc makes you MORE shortsighted. Say if you're on a computer 24 hours with your specs on, the computer is at 2/3m normally so your eye has to accommodate to there. Easiest way of thinking about it is that the dioptric power of your accommodation should be 1.5Dioptres to do that (from the focal length, 1/(2/3) = 1.5). This makes you more short sighted if your muscles spasm from looking at the screen that long and you can become artificially more short sighted for a little while. Your eye muscles can only make your eye stronger so i doubt it's any kind of muscle thing unless your specs were too strong in the first place as mentioned above. The only other time i've seen something similar is when someone went from a -4.00 to a -2.00, had the same symptoms as you. BUT, that is one hell of a shift and was very sudden. She went back to a -4.00 within a week. There was no explanation for that but she was on a lot of pyschosis meds and associated things but didn't know the name, i reckon it was something to do with those. I'd just see how it goes dude Blimey, I need glasses too now after reading that. Quote Link to comment Share on other sites More sharing options...
Kopite Posted July 30, 2008 Share Posted July 30, 2008 Blimey, I need glasses too now after reading that. Well i do work for speccies, we have ways of making you need them when you didn't previously Quote Link to comment Share on other sites More sharing options...
Ian C Posted July 31, 2008 Author Share Posted July 31, 2008 OK brace yourselves, here's my current prescription: SPH R -4.50 L -4.00 CYL R -0.50 L -1.25 AXIS R 80.0 L 25.0 The rest is blank apart from 11.00 under I think Inter-ADD?

Supragal Posted July 31, 2008 Share Posted July 31, 2008 Christ I'm so blind. I'm like -6.75 or something rubbish When do they stop getting worse!!! oh, when you're 34 apparently... Quote Link to comment Share on other sites More sharing options...

I did used to refuse to wear glasses, it was quite something when I eventually gave in.

The 11.00 is gonna be the back vertex distance for where you were tested, as in how far from your eye the lens was. It's written in the wrong box as you're too young for an INTER ADD Quote Link to comment Share on other sites More sharing options...
