What Is Sleeping in Contacts: Safe or Not?

“Sleeping in contacts” means wearing your contact lenses overnight while you sleep, rather than removing them before bed. You might do this intentionally with lenses labeled for overnight or extended wear, or accidentally (falling asleep with daily lenses in).

You’ve probably heard warnings—but what are the facts behind sleeping with contact lenses? And is it ever truly safe?

Why It Matters for Your Health and Well-Being

Your eyes need oxygen to stay healthy, and so does the clear layer over your eye, the cornea. During the day, oxygen passes easily through contact lenses. But overnight, when your eyes are closed and covered, oxygen and tear exchange drop significantly—even more so with contact lenses.

Sleeping in contacts can lead to:

• Redness, discomfort, dry eyes
• Higher risk of infections like microbial keratitis (eye inflammation that can cause vision loss)
• Corneal ulcers or damage
• Reduced eye health over time, even with soft lenses

Good eye care means supporting your eyes' natural recovery and defense. That’s why experts stress caution around sleeping in contact lenses, even if the packaging says “overnight safe.”

Common Challenges and Myths Around Sleeping in Contacts

• “It’s okay if I do it just once.” — Even a single night of sleeping in the wrong type of lens can irritate or expose your eyes to infection.
• “My lenses are breathable, so I’m fine.” — While newer silicone hydrogel lenses offer better oxygen flow, no lens is risk-free for overnight use.
• “Only people with sensitive eyes need to worry.” — Anyone can develop problems, even if you’ve never had trouble with your contacts before.
• “I can use eye drops if my eyes feel dry.” — Drops may temporarily ease dryness, but they can’t stop infections or long-term corneal damage.
• “Monthly lenses are designed for sleeping.” — Only certain lenses are FDA-approved for extended wear; most (including dailies) are not.

Understanding these myths helps you make safer choices for your eye wellness!

Step-by-Step Solutions, Strategies, or Routines to Try

1. Check Your Lens Approval: Only wear contacts overnight if the brand is prescribed and labeled for “extended (overnight) wear.” Even then, regular check-ins with your eye doctor are a must.
2. Set a Bedtime Reminder: Set an alarm, use a sticky note, or tap a phone reminder to remove your contacts before sleep. Making it a routine is key!
3. Have a Clean Lens Case & Solution Ready: Keep your lens case and solution next to your bed or bathroom so it's convenient to remove, clean, and store your lenses nightly.
4. Stay Hydrated: Drink enough water during the day to support your eyes’ natural moisture and overall health.
5. Keep Spare Glasses Nearby: The easier it is to swap your contacts for glasses at night, the less tempted you’ll be to “just sleep in them tonight.”
6. Follow the “Rub and Rinse” Rule: Always rub and rinse your lenses with proper solution—even if using “no-rub” types—for extra safety.
7. If You Accidentally Sleep in Contacts:
   • Remove them ASAP in the morning
   • Let your eyes rest and use glasses for the day
   • Watch for pain, redness, blur, or discharge—see a doctor if these appear

Tips from Experts and Scientific Studies

• CDC and American Academy of Ophthalmology: Sleeping in non-overnight contacts increases infection risk by 6–8x compared to regular removal.
• Dr. Michelle Andreoli, AAO spokesperson: “Overnight wear remains the top risk for severe eye infections—regardless of lens type.”
• Peer-reviewed studies: Lenses marked “extended wear” still carry a higher risk of microbial keratitis than daily wear with nightly removal (Ophthalmology, 2022).
• Doctor’s tip: “If your eyes are red, painful, or extra sensitive to light after sleeping in contacts—even once—see your eye doctor immediately.”
