Why sleeping in contacts is risky
Your cornea gets oxygen from the air. When your eyes are closed with a lens on, less oxygen reaches the cornea, and bacteria can more easily build up under the lens. This raises the risk of a corneal infection, which can be painful and in some cases threaten vision.
What if you fall asleep in them?
Take the lenses out as soon as you wake up and give your eyes a break. If your eyes feel comfortable, wear glasses for the rest of the day. If you notice redness, pain, light sensitivity, discharge or blurry vision, call us right away.
Some lenses are approved for overnight wear
A few lenses are approved for extended wear, but they still carry a higher infection risk than removing lenses every night. Only sleep in lenses if your doctor has prescribed them for it.
Simple habits that protect your eyes
Daily disposable lenses are one of the easiest ways to lower risk, since you start with a fresh pair every day. Your doctor can tell you whether they're a good fit at your next contact lens exam.
