Contact Lens Prescription
I have been wearing contact lenses for three years, off and on. I still have a few boxes left from a prescription that was given to me three years ago... I don't want to waste the contact lenses, but at the same time, don't want to harm my eye health.
Is there much harm in using contact lenses from a prescription that is past the prescription expiration date (mine is from nearly three years ago)? I see fine when wearing them... the main issues are cost and not wanting to throw out extra lenses.

I don't think its about contacts expiring but its more about your prescription about contacts changing. If you go for your eye dr. visit once every two years and they tell you that your prescription hasn't changed...then that would be the time to mention how many boxes you have left. If you have no insurance and its a matter of cost to you, here's what I found on line, tests have not concluded yet 100% that there would be problems using the contacts in unopened packs. Here's a quote:
Blister packs are heat sealed and made impermeable to bacteria therefore, theoretically, sterility of these contact lenses should only be compromised once the seal is broken. And here's the link:
