Don’t…

Don’t put them in with mittens

Don’t trade contacts with your friends

Don’t clean them with hot sauce

But for serious:

Do wash your hands before insertion/removal

Do clean your contacts everyday

Do clean your contacts with new solution everyday

Do put your contacts in their case while not using them

Do replace your contact lenses on their proper schedule (daily, bi-weekly, monthly)

Don’t shower while wearing your contacts

Don’t sleep with your contacts (unless they are Night & Day)

Don’t wear damaged (ripped or misshapened) contacts

Don’t put your right/left contacts in the wrong eyes

Don’t over-wear your contacts – take a couple days off a week to keep your eyes healthy
