Keeping lenses to long?

Question

ok for exaple you have contacts that you have to change every month what will happen if you dont change your contacts and keep them for up to three months.

Answer 1

Dirt and debris build up on them (personally, I would never want to put a really dirty contact in my eye), and they become uncomfortable, sticky, and can even lead to eye damage. I'll forget sometimes and use the same pair for a month and a half, but never more than two months. Make sure you change them regularly!

Answer 2

dry eye, serious infections, neovascularization, corneal ulcers, giant papillary conjunctivitis, and the inability to ever wear contacts again
