Most people who wear contact lenses know they should take them out before falling asleep. However, according to the CDC, a third of contact lens wearers admit to sleeping with their contacts at least occasionally, a habit that can increase the risk of potentially sight-robbing eye infection 8-fold. If you accidentally fall asleep with your contacts, apply artificial tears to loosen the lenses from your eyes, and then carefully remove them. Wear glasses the rest of the day.
