You’re exhausted. You’re already in bed. And then it hits you…
“Oh no—I still have my contacts in.”
So you ask the big question: Can you sleep in contact lenses?
At Lake Norman Eye Care, Dr. Mason Williams and Dr. Angela Harris hear this question all the time. The short answer? Most of the time—no, you shouldn’t.
But the why matters, and understanding it could save your vision.
Let’s break it down 👇
Why Sleeping in Contacts Is Usually a Bad Idea 😴👀
Your cornea (the clear front surface of your eye) gets oxygen directly from the air—not from blood vessels. When your eyes are closed and covered by contact lenses, oxygen levels drop significantly.
This can lead to:
- Eye infections (some can be vision-threatening)
- Corneal ulcers
- Severe redness and pain
- Blurred vision
- Permanent corneal scarring
According to the CDC, sleeping in contacts increases your risk of eye infection by 6–8 times, even if it’s “just a nap.”
But What About Contacts Approved for Overnight Wear?
Great question—and this is where things get a little nuanced.
Some lenses are FDA-approved for extended or overnight wear, meaning they can be slept in under close medical supervision. These lenses are made from materials that allow more oxygen to pass through to the eye.
However—and this is important—even with these lenses:
The risk of infection is still higher than removing them nightly
Not everyone is a good candidate
Strict hygiene and follow-up exams are critical
Dr. Williams and Dr. Harris always emphasize that “approved” does not mean “risk-free.”
What Happens If You Accidentally Fall Asleep in Contacts?
It happens—life is busy, and you’re human. If you wake up with contacts still in:
Do not panic—but don’t ignore it either.
What to do:
- Do not remove them immediately if your eyes feel dry
- Use preservative-free lubricating drops
- Wait until your lenses move comfortably
- Remove them gently
- Do not put contacts back in that day
If you experience pain, redness, light sensitivity, or blurry vision—call Lake Norman Eye Care right away.

How to Protect Your Eyes (and Your Vision)

Still Wondering If Your Contacts Are Safe for You?
