A lot of contact lens wearers will sleep with their lenses on at some point, some by accident others because convenience. The problem arises when you continuously sleep with your lenses, without updating your cleaning regimen.

Look after your lenses, seek advice from your optom when you’re not sure (I’m generally available all the time) and keep your eyes healthy.
