Falling asleep with contact lenses still in your eyes happens more often than you might think. But is it safe — and does it depend on the type of lenses you wear?
The short answer is: most contact lenses are not designed for sleeping in, and doing so can increase the risk of eye irritation and infection. Let’s explain when it might be allowed, when it’s risky, and what you should do if it happens.
Why Sleeping in Contact Lenses Is Usually Not Recommended
When you sleep, your eyes receive less oxygen. Contact lenses already limit oxygen flow to the cornea, and wearing them overnight reduces it even further. This can lead to dryness, redness, blurred vision, or more serious eye problems.
Sleeping in lenses also increases the risk of bacteria building up on the lens surface, which can cause eye infections such as keratitis.
This applies to most lenses, including Daily Contact Lenses and standard Monthly Contact Lenses.
What Are Extended Wear Contact Lenses?
Some contact lenses are specifically approved for overnight wear. These are known as extended wear contact lenses and are made from highly breathable materials that allow more oxygen to reach the eye.
However, even with extended wear lenses, sleeping in contacts should only be done if your eye care professional has advised it. Overnight wear still carries a higher risk than removing lenses before sleep.

Is It Ever Safe to Sleep in Contact Lenses?
Sleeping in contact lenses may be considered acceptable only if:
Your lenses are approved for overnight wear
Your optician has confirmed they are suitable for your eyes
You follow strict wearing and replacement schedules
Even then, many eye care professionals recommend removing lenses at night whenever possible.
What If You Accidentally Fall Asleep in Contact Lenses?
If you fall asleep with your lenses in once, don’t panic. When you wake up:
Do not remove lenses immediately if your eyes feel dry
Use contact-lens-safe eye drops to rehydrate your eyes
Blink gently for a few minutes
Remove the lenses carefully once your eyes feel comfortable
If your eyes feel sore, red, or sensitive to light after removal, stop wearing lenses and consult an eye care professional.

Which Lenses Should Never Be Worn Overnight?
You should never sleep in daily disposable lenses. These lenses are designed for single-day use and are not made to withstand overnight wear.
👉 Explore safer options in Daily Contact Lenses
Sleeping in daily lenses significantly increases the risk of irritation and infection.
Does Sleeping in Lenses Affect Dry Eyes?
es. Sleeping in contact lenses can worsen dry eye symptoms, especially if you already experience dryness or discomfort during the day. Reduced oxygen and moisture overnight can leave your eyes feeling gritty and irritated the next morning.
If dry eyes are a concern, daily lenses or lenses designed for moisture retention may be a better option.

Our Recommendation at WeLoveLenses
As a general rule, remove your contact lenses before sleeping, even for short naps. It’s the safest way to protect your eye health and keep your eyes comfortable long-term.
If you’re interested in lenses approved for overnight wear, always consult your eye care professional before switching.
Final Thoughts
While some contact lenses are designed for extended wear, sleeping in contact lenses is rarely the best choice for eye health. Removing your lenses before bed helps reduce the risk of infection, dryness, and discomfort — and keeps your eyes healthy for the long run.
