What will happen to my eyes?!
Question: What will happen to my eyes?
Answers:
the reason they have an usage date is to do with the bacteria that grow on them (pesky things get everywhere!)
Once the bacteria get to a certain level you can get an eye infection which if left untreated could lead to blindness.
You are not supposed to wear them longer than advised due to protein and bacteria build up on them and it can cause problems. I have two week contacts and I wear them for a month but I can tell at the end of the month when it is time to change them because the quality diminishes.
You'll go blind
