What was the longest time you have worn your contacts for?
-
I broke my own record yesterday... 45 hours! What will happen if wear for too long anyway? I don't feel any discomfort though..
-
hmm~ For me it's around 8~9 hours bah..

don't try wearing for too long
Your contact lenses are a barrier between your cornea and the rest of the world. While this may not seem like a bad thing, it is. Your cornea, like every other part of the body, requires Oxygen. Too little oxygen, and complications begin to arise. So what happens when you fall asleep with your contact lenses in? Your cornea is being denied oxygen by the lens itself. This leads to a condition known as hypoxia.
Corneal hypoxia changes the rate of metabolism in the epithelium. This in turn causes a decrease in glycogen, and makes the cornea more sensitive and prone to adhesion and refractive error changes. Continued progression includes corneal ulcers.
Since the cornea is more adhesive, this increases the chances of any buildup on the cornea itself, including protein buildups, which cause bacterial infections and corneal ulcers. Short term effects include extreme intolerance to contact lenses. Lens intolerance can be overcome by RGP Contact Lenses, but by this point, you should just ditch them all together. Give your eyes a chance to heal, and suck it up and wear glasses. -

i heard if your eyes get too dry your contacts might get stuck to your eye ball, or smth like that! -
My brother had been wearing contact lenses for 9 years already. Recently his eyes felt very uncomfortable so he went to see an eye specialist. The specialist said there are ulcers growing inside the eyes and that if he had not seen the doctor and continue wearing contact lenses for 3 more weeks he would have gone blind (not sure the doc is being truthful here anot).
The specialist also mentioned that every year quite a number of ppl go blind from wearing contact lenses. I'm wearing contact lenses too but now I try to wear for shorter periods by taking them off once I reach home. -
if it doesn't stay on the pupil. it means you put it in the wrong end. lenses are made to fit the pupil. so it doesn't move about.Originally posted by polarsnake:Last time I use acuvue the lens always go up above my eyeball... damn scary..

0hrs 0mins 0 secs.
I wear spec one... -
what about colour contacts?
-
6 mths. Soft monthly contacts. I was going through severe depression back then. Didn't bother to remove them until my eyes had a severe reaction & had to see a doc. When I removed them, my eyes felt raw and wounded for 2 weeks (despite using the strongest eye medication available on the market).
My eyes have healed but I can no longer wear contacts for more than a few hrs at one go.. if i do, they'll start to produce alot of sticky discharge -
close to 2 days. and i had an eye infection after that. oh and because i slept in contacts. thats why.
