Can You Sleep in Colored Contact Lenses? Risks and Safe Practices

Quick Answer

No, you should not sleep in colored contact lenses, even for a nap. Overnight wear dramatically increases the risk of eye infections, corneal ulcers, and other complications. Always remove your lenses before sleeping, and if you accidentally fall asleep with them, remove them as soon as you wake and give your eyes a break.

It happens to almost everyone: you're tired, you lie down for a quick nap, and you wake up hours later with your colored contacts still in. While it might feel harmless, sleeping in contact lenses is one of the riskiest habits for your eye health. The cornea needs oxygen, and lenses—especially colored ones—can restrict that supply when your eyes are closed.

This article explains the real risks of sleeping in colored contacts, what to do if you've already napped with them, and how to build safe habits that protect your eyes without giving up the look you love.

What Happens When You Sleep with Contacts In?

When you sleep, your eyes are closed, which reduces the oxygen supply to your cornea. Contact lenses, even breathable ones, further limit that oxygen. This can lead to corneal hypoxia, a condition where the cornea doesn't get enough oxygen, causing swelling, blurred vision, and increased risk of infection.

Additionally, while you sleep, your tear production decreases. This means debris and bacteria are more likely to stick to the lens surface and accumulate. Over time, this can lead to irritation, redness, and potentially serious infections like microbial keratitis.

• Remove your contacts before any sleep, including naps.
• Always wash your hands before handling lenses.
• Use fresh solution to store lenses, never tap water.

The Risks of Overnight Wear

The most serious risk is microbial keratitis, an infection of the cornea that can lead to ulcers and even vision loss if not treated promptly. Studies show that sleeping in lenses is one of the biggest risk factors for this condition. Even a single night of overnight wear can increase your risk significantly.

Other risks include corneal neovascularization (growth of new blood vessels into the cornea), which can permanently affect your vision. You might also experience dry eyes, redness, and discomfort that lasts for days after just one night of sleeping in lenses.

• If you wake up with red, painful, or light-sensitive eyes, remove your lenses immediately and see an eye doctor.
• Never sleep in lenses that are not specifically approved for extended wear.

Safe Practices for Colored Contact Wearers

To keep your eyes healthy while enjoying colored contacts, always follow the recommended wear schedule. Most colored lenses are designed for daily wear only, meaning you should remove them before sleeping. Always use fresh contact lens solution to clean and store your lenses, and replace them according to the manufacturer's schedule.

If you frequently fall asleep with your lenses, consider setting a reminder to remove them, or keep a backup pair of glasses for times when you're tired. Also, never wear your lenses while swimming or showering, as water can introduce harmful microorganisms.

• Set an alarm to remove lenses if you're prone to napping.
• Always have a contact lens case with fresh solution handy.
• Replace your lens case every three months.

Diagnosis: Is It Safe to Sleep in Colored Contacts?

• Symptom: You accidentally fell asleep with your colored contacts in and woke up with them still on. This is common, but it doesn't make it safe.
• Likely Cause: Sleeping with lenses reduces oxygen to the cornea and increases the risk of infection and irritation. The longer you sleep with them, the higher the risk.
• Corrective Action: Remove your lenses as soon as you wake up, clean them thoroughly, and give your eyes a break by wearing glasses for the rest of the day. If your eyes are red, painful, or sensitive to light, see an eye doctor immediately.
• When to Stop and Choose Another Option: If you find yourself regularly sleeping in your lenses, consider switching to daily disposable lenses or simply removing them before any nap. Your eye health is more important than convenience.

Products That Support Healthy Wear

• FreshTone® Super Natural Colored Contacts - Ivory Color: Made with high-quality materials that are safe, comfortable, and breathable, making them perfect for extended wear. Even breathable lenses are not safe for sleeping, but choosing a breathable option like this can reduce the risk of dryness and discomfort during normal daily wear.
• FreshTone® diva brown plano eye contact lens: No prescription needed, making them a great choice for those who want to try colored lenses without a vision correction. Even plano lenses carry the same risks of sleeping in contacts, so always remove them before bed regardless of whether you need vision correction.

Sleeping in colored contacts is never a safe practice. The risks to your eye health are too serious to ignore. By following safe wear habits and removing your lenses before sleep, you can enjoy the beauty of colored contacts without compromising your vision. If you accidentally nap with them, don't panic—just remove them promptly and monitor your eyes for any signs of trouble.
