Can You Sleep With Contacts In?

Since contact lenses reduce moisture in your eyes, in most cases you’ll just wake up with dry eyes if you sleep with contacts in. There are, however, some more serious side effects that can result from overnight contact use. Extended contact use deprives your eyes of oxygen, causing unnecessary strain to the cornea. Wearing contacts lenses too long can potentially damage your cornea’s surface, making your eyes more susceptible to infection. You’re as much as 6 to 8 times more likely to acquire an eye infection when wearing contact lenses while sleeping, whether you fell asleep with them in intentionally or not. Adolescents and young adults are more prone to developing contact lens-related eye infections, which is attributed to less rigorous hygiene.
