Many contact lens wearers have asked themselves this question: is it really that bad to fall asleep with your lenses in? Whether it's after a long day, an unexpected nap, or a short night, the temptation to keep them in can be strong. However, sleeping with your lenses in is not without risk.
Why it is not recommended to sleep with your lenses in
During sleep, the eyes close and the amount of oxygen reaching the cornea naturally decreases. Lenses then act as an additional barrier, further reducing the oxygen supply that is essential for eye health. As a result, the cornea dries out and becomes more vulnerable to infections, irritation, and micro-injuries.
Sleeping with contact lenses can cause:
- Red, painful eyes upon waking up;
- Temporary blurred vision;
- A burning sensation or feeling of having a foreign body in the eye;
- An increased risk of corneal infection, such as keratitis.
Exceptions: certain lenses designed for extended wear
There are special contact lenses called extended wear lenses or overnight lenses. They are made of oxygen-permeable materials (such as silicone hydrogel), which allow the eyes to breathe better.
However, even these lenses require regular monitoring. Extended wear still slightly increases the risk of infection compared to daytime wear with removal each night. It is therefore essential to follow the prescribed wear schedule and consult your optometrist for appropriate follow-up.
Best practices for healthy eyes
- Always remove your lenses before sleeping
- Clean and disinfect your lenses every night with an appropriate solution.
- Replace them at the recommended frequency (daily, bi-monthly, or monthly).
- Never wear damaged or expired lenses.
- Consult your optometrist immediately if you experience pain, redness, or persistent blurred vision.
In summary
Sleeping with your contact lenses in is not harmless: it can compromise the health of your eyes, even if you don't experience any immediate symptoms. If you want a practical solution to avoid removing them every night, talk to your optometrist. They can assess whether you are a good candidate for safe extended wear contact lenses.
