Can You Sleep in Your Contacts? Let’s Talk About It
Introduction
We've all been there. It’s late, you’re curled up in bed after a long day, and the last thing you want to do is peel yourself off the pillow to take out your contacts. Or maybe you’ve drifted off on the couch mid-movie without realizing you're still putting on them. So the question comes up: Is ittruly that bad to sleep in your contacts?
The short answer? It can be. While it may not cause immediate harm in a single instance, regularly sleeping in your lenses—especially if they’re not approved for overnight wear—can put your eye health at serious risk. In this handbook, we’ll break down what happens to your eyes when you fall asleep with your contacts in, the real risks you should know about, and what to do if it happens.
What Happens When You Sleep in Contacts?
To grasp why sleeping in contacts can be harmful, it helps to know what your eyes need to stay healthy. Your cornea (the clear front part of your eye) gets oxygen directly from the air—not from blood vessels like most other body parts. When you're awake and blinking, this oxygen exchange is steady. But eye lenses—especially thicker or older types—create a barrier that reduces oxygen flow.
When you close your eyes during sleep, oxygen supply to your eyes drops even further. Add a eye lens into the mix, and you're creating a low-oxygen environment on your eye’s surface. That’s a recipe for trouble.
The Real Risks of Sleeping in Eye lenses
Falling asleep in your lenses once might not leave you with permanent damage, but repeated or prolonged wear can absolutely impact your eye health. Here's what could happen:
Corneal Hypoxia
Hypoxia occurs when your cornea doesn’t grab enough oxygen. It can cause swelling, blurry vision, discomfort, and an increased risk of infection. In some cases, it can even change the shape of your cornea.
Increased Risk of Infections
When your eyes are closed and covered by a lens, your tear film (which helps clear debris and bacteria) doesn’t circulate as effectively. This creates the ideal environment for harmful microbes to multiply. The most serious infection is microbial keratitis—a painful condition that can cause permanent vision loss if untreated.
Corneal Ulcers
Sleeping in lenses increases your risk of developing ulcers on the cornea. These are open sores that can be incredibly painful and require immediate medical attention. They can additionally cause scarring, which may affect your vision long term.
Eye Irritation and Redness
Even if infection doesn’t set in, sleeping in contacts can leave your eyes feeling dry, itchy, and red when you wake up. Chronic irritation can make putting on lenses more uncomfortable in general.
Are There Contacts That Are Safe for Sleeping?
Yes—but with a big asterisk.
There are specialty lenses made from silicone hydrogel materials that are FDA-approved for extended or overnight wear. These lenses are more breathable and allow significantly more oxygen to reach the cornea. That said, even these “sleep-approved” lenses carry a higher risk of complications than daily removal.
Sleeping in lenses—any lenses—should only be done under the supervision of an eye care professional. Regular checkups and strict hygiene are non-negotiable if you go this route.
So while extended-wear lenses exist, the safest practice is still to take out your lenses before bed. At all times.
Oops—You Slept in Your Contacts. What Now?
First, don’t panic. Many people do this at least once. But how you handle it next matters.
Here’s what to do if you fall asleep in your lenses:
-
Take out them as soon as you wake up, but don’t yank them out.
-
If your eyes feel dry or the lenses seem stuck, use rewetting drops and blink a few times before removal.
-
Steer clear of rubbing your eyes, as this could irritate or scratch the cornea.
-
Watch for symptoms: redness, light sensitivity, blurred vision, or pain.
-
If any of these occur, call your eye doctor right away—especially if symptoms worsen over time.
Even if you feel fine, give your eyes a break by going glasses-only for the rest of the day.
How to Steer clear of It from Happening Again
Life gets busy, and bedtime routines don’t at all times go according to plan. But your eye health is worth the effort. Here’s how to make contact removal part of your nightly habits:
-
Create a ritual. Pair contact removal with brushing your teeth or skincare so it becomes automatic.
-
Keep a lens case and solution by your bed just in case you’re too tired to make it to the bathroom.
-
Try daily disposables. These are removed and tossed every night—no rinsing or keeping required.
-
Set a phone reminder or use a smart assistant to nudge you if you often forget.
-
And most importantly, grab regular eye exams to ensure your lenses are the right fit and type for your lifestyle.
