It happens to everyone at some point. A quick break on the couch turns into a full nap, or you fall asleep earlier than planned with your contact lenses still in. The next morning, your eyes may feel dry, irritated, or slightly blurry, leading to questions about what overnight wear does to the eyes.
While a single incident may not cause noticeable harm, sleeping in contact lenses increases the risk of irritation and eye complications. Keep reading to learn why optometrists recommend removing lenses before sleeping.
Can you sleep with contact lenses in?
No, eye doctors generally advise against sleeping in contact lenses, even during short naps.
Your eyes rely on oxygen and tear exchange to stay healthy and function properly. When your eyelids close, oxygen levels naturally decrease. Contact lenses add another barrier that limits oxygen flow to the cornea.
That combination can raise the risk of:
- Eye infections
- Corneal swelling
- Corneal ulcers
- Red, irritated eyes
- Scratches on the corneal surface
One accidental night usually does not lead to serious damage, but repeated overnight wear significantly increases the risk of eye issues.
Oxygen and your eyes
The cornea does not contain blood vessels. Instead, it receives oxygen directly from the air and the tear film. During sleep, blinking stops and tear circulation slows, which already reduces oxygen availability.
Contact lenses further restrict oxygen flow, especially overnight. When the cornea receives less oxygen, it becomes more vulnerable to inflammation and infection.
This can lead to:
- Slower healing of the eye surface
- Increased dryness after waking
- Greater sensitivity to light
- Higher risk of bacterial growth
What about extended-wear contact lenses?
Some contact lenses receive FDA approval for overnight use in specific cases. These lenses allow certain patients to sleep in them for limited periods. Extended-wear lenses feature a thinner material than daily-wear contacts, helping increase the amount of oxygen that reaches the eye.
Even so, overnight wear is not appropriate for everyone. Eye doctors evaluate several factors before recommending extended-wear soft contact lenses:
- Overall eye health
- Tear quality and dryness level
- Contact lens type and oxygen permeability
- Wearing habits and hygiene routines
- History of eye infections or irritation
What to do if you fall asleep with contacts in
Waking up with contact lenses still in your eyes can feel uncomfortable, especially if your eyes feel dry or tight.
It’s important to take the contacts out gently:
- Blink several times to help rehydrate the eye
- Use lubricating drops if recommended
- Wait a few minutes for the lenses to loosen
- Remove lenses gently without forcing them
- Let your eyes rest before wearing contacts again
If you notice ongoing redness, pain, or blurred vision after removal, schedule an eye exam.
Can I take a short nap with contacts in?
No, even short naps carry risks. A brief nap may create less risk than sleeping for several hours, but it can still lead to dryness, irritation, and surface stress on the eye.
After napping in contact lenses, you may notice:
- Mild eye dryness
- Slight redness
- Blurry or fluctuating vision
- Increased lens discomfort
Removing contact lenses before any nap or rest period remains the safest option whenever possible.
Healthy contact lens habits
Good daily care reduces complications and keeps contact lenses comfortable.
Helpful habits include:
- Removing lenses before sleeping or napping
- Replacing lenses on schedule
- Washing and drying hands before handling lenses
- Using fresh solution daily
- Never reusing old solution
- Replacing lens cases regularly
- Scheduling routine contact lens exams
