Many people use contact lenses to correct their vision, but not everyone knows the risks and dangers that come with sleeping with them on.

Wearing contact lenses while sleeping can pose a significant threat to eye health and can cause various complications such as infections, corneal ulcers, and vision loss.

Why do some people sleep with contact lenses?

Sometimes, people forget to remove their contact lenses before going to bed, while some wear them overnight to reduce the hassle of putting them in and out every day.

Additionally, those who have difficulty with taking the lenses out may feel more comfortable sleeping with them on.

Risks and dangers of sleeping with contact lenses

Here are some of the risks and dangers of sleeping with contact lenses:.

1. Infections

Sleeping with contact lenses significantly increases the risk of eye infections.

Your eyes need oxygen to stay healthy, and wearing lenses overnight can prevent oxygen from reaching your eyes, creating a breeding ground for bacteria and other harmful microorganisms. As a result, you may suffer from conjunctivitis (pink eye) or keratitis, an infection of the cornea.

2. Corneal ulcers

Corneal ulcers are deep sores that form on the cornea. They result from a bacterial, viral or fungal infection that settles on the eye.

Sleeping with contact lenses can increase the risk of these sores’ formation, leading to vision loss or even blindness.

3. Reduced corneal oxygen supply

When you sleep with contacts on, the cornea is unable to get oxygen from the tears and the atmosphere. As mentioned earlier, this reduced oxygen supply can result in eye infections and corneal ulcers.

In the presence of contact lenses, the oxygen supply is reduced by up to 80% compared to when you wear glasses.

4. Discomfort and dry eyes

Sleeping with contacts also means that you are likely to experience dry eyes. The contact lenses make it difficult for oxygen and tears to reach the surface of the eye. As a result, you may suffer from red eyes, irritation, and general discomfort.

5. Scratches on the cornea

Movement during sleep can cause contact lenses to shift and scratch the cornea, damaging the eye’s surface. This could result in permanent vision loss or a need for a corneal transplant in severe cases.

Prevention of risks and dangers of sleeping with contact lenses

It’s always best to remove your contact lenses before going to bed. However, if sleeping with contacts is unavoidable, follow these guidelines:.

1. Use the appropriate type of contacts

Some types of contact lenses are meant for extended wear, including overnight. Be sure to ask your optometrist whether the lenses he or she prescribes are safe for overnight wear.

2. Replace lenses regularly

It’s crucial to replace your contact lenses according to the prescribed schedule. Do not use them beyond their expiry date.

3. Clean thoroughly before wearing and after removal

Ensure that you clean your contact lenses thoroughly before putting them in your eye. After wearing them, make sure you clean them again to remove any dirt or debris that might have accumulated on them during the day.

This helps prevent eye infections and complications.

4. Take breaks from wearing contacts

Avoid wearing contacts for an extended period. Instead, allow your eyes to breathe. If possible, switch to glasses for a day or two during the week.

5. Use artificial tears

If you experience dry eyes from wearing contacts, use artificial tears as recommended by your eye care professional. This will help keep your eyes moisturized and reduce discomfort.

In conclusion

Wearing contact lenses is an excellent way to correct vision, but it can be risky when done incorrectly. To prevent complications and protect your eye health, it’s crucial to remove contact lenses before going to bed.

If you must wear them for an extended period, follow the guidelines provided by your doctor and optometrist. Your eyes are precious, so ensure that you take good care of them.
