Sleeping with contact lenses: risks and consequences

Although many users know this, it remains one of the most frequently asked questions: What happens if I sleep with my contact lenses in? The answer is simple: sleeping in contact lenses is not recommended and can have serious consequences for eye health.

Sometimes it happens out of carelessness, other times out of convenience. But even one night can increase the risk of infection and discomfort. Here's what really happens and how to avoid problems.

Why shouldn't you sleep with contact lenses?

Contact lenses reduce the amount of oxygen reaching the cornea. During the day, blinking and natural lubrication compensate for this effect. But when you sleep, your eyes remain closed, and oxygenation decreases even further.

This creates an ideal environment for bacteria to grow and increases the possibility of eye complications.

Main risks of sleeping with contact lenses

• Eye infections: such as keratitis, which can be painful and require urgent treatment.

• Dryness and irritation: Upon waking, your eyes often feel rough or dry.

• Temporary blurred vision: caused by lack of oxygen in the cornea.

• Increased deposit buildup: Proteins and debris adhere more to the lens overnight.

What to do if you fall asleep with contact lenses in?

• Remove them as soon as you wake up, never force your eye if it is dry.

• Use artificial tears before removing them to avoid damage to the ocular surface.

• Let your eyes rest for the rest of the day with glasses.

• If you experience pain, severe redness, or persistent blurred vision, see a specialist.

Are there contact lenses suitable for sleeping?

Yes, there are contact lenses designed for extended or continuous wear, allowing you to sleep in them for several days. However, these are not common and should only be used under medical supervision.

Conclusion

Sleeping in contact lenses may seem harmless, but the risks outweigh any momentary comfort . The general recommendation is to always remove them before bed, even for short naps. Your eyes need oxygen and rest to stay healthy and comfortable.
