Contact Lens Prescription
I use 14-day contact lenses (Acuvue Oasys) and have a few boxes left for a prescription I was given almost two years ago. I still want to continue using them, it's financially difficult for me to get a new prescription and lenses, so I hope the ones I have will do. My question is, are prescriptions pretty much stable after 2 years? For about how much longer can I use my contacts before I absolutely have to get another prescription? I am 29 years old, so as far as I know, my vision should be stable and I should hopefully be able to use the lenses for a while longer, but I just want to make sure.

I think it really depends. I go in every year for an eye exam and my prescription always seems to change.
I'm supposed to chance mine every month but I always end up wearing them longer.
I really don't want to give you bad advice or hurt your eyes or anything but this is just my experience. My prescription never changed dramatically though.
You usually know when your vision is way off when you start getting headaches or you're not seeing as well as you used to.

Yes, you can use them. I always found I had contacts left by time it was time for my next appt. So if my eyesight had not changed, i let the dr. know how many I had left.
I always wore mine for longer than they suggest. You kind of can tell when a pair no longer feels comfortable even after cleaning and you must break out a new pair. They say they worry about a person getting germs, infections if you dont use a new pair often enough. I personally think it was a gimmick to make more money on re-sales of lenses.
I think the solution that new contacts sit in is what preserves them. The solution doesn't age because air can't get to it, its sealed. However, its another story if its an old pair you discover in a contact case at the back of the medicine cabinet that you've worn before and forgot to toss and now due to a broken contact have no choice but to wear. That's old and I wouldn't trust it except longer enough to wear to drive to dr. to get replacements.
