Sleeping with contact lenses in your eyes can have severe consequences for your eye health. Even a short nap can increase your risk of eye infection, with the risk of microbial keratitis, a form of corneal inflammation, being over five times higher. This is because contact lenses limit the cornea's exposure to oxygen, allowing bacteria and microorganisms to become trapped in your eye. In severe cases, this can result in vision loss or even blindness.

What You'll Learn
Increased risk of eye infection
Sleeping in your contact lenses can have adverse effects on your eyes, one of the most common being an increased risk of eye infection. Even a short nap or accidentally dozing off with your contacts in can put you at risk of serious eye infections.
Contact lenses are medical devices and should be used according to your eye doctor's directions. When you sleep with your contacts in, the lenses act as a barrier, reducing the amount of oxygen your cornea receives. The cornea of your eye relies on oxygen from the atmosphere, which dissolves in the tear film that coats your eye. This oxygen is necessary for the cornea to protect itself from microorganisms. When there isn't enough oxygen supply, corneal cells can get damaged, leading to various symptoms and complications.
Additionally, wearing contacts while sleeping can trap bacteria and microorganisms in your eyes, increasing the likelihood of infections. This is especially true if you do not handle your contacts carefully and correctly. Poor contact lens hygiene, such as swimming or showering with your contacts in, further increases the risk of infection.
The risk of specific types of eye infections, such as microbial keratitis and fungal keratitis, is significantly higher when sleeping with contact lenses. Microbial keratitis is an infection and inflammation of the cornea, which can lead to vision loss if left untreated. Fungal keratitis is also a leading cause of blindness in certain regions.
If you accidentally fall asleep with your contacts in, it is important to remove them as soon as you wake up. You should then give your eyes a break and avoid wearing contacts for at least a day. Monitor your eyes for any signs of infection, and if you experience any eye-related symptoms, consult an optometrist or eye doctor immediately.

Vision loss
Sleeping in your contact lenses can have severe consequences for your eyes, including permanent vision loss. This is primarily due to the increased risk of eye infections, which can cause irreversible damage to the cornea and even lead to blindness.
Contact lenses are medical devices that should be used according to your eye doctor's directions. Sleeping with contacts in your eyes substantially raises the risk of eye infections, in particular microbial keratitis, which is an infection and inflammation of the cornea. The cornea, the protective dome on the surface of your eye, relies on oxygen from the atmosphere, which dissolves in the tear film that coats your eye. Contact lenses act as a barrier, reducing the amount of oxygen available to the cornea, which can lead to corneal cell damage.
This lack of oxygen creates an ideal environment for bacteria and microorganisms to thrive, increasing the risk of infection. Even a single night of sleeping with contacts can have adverse effects, and the risk of infection increases six to eightfold. The risk of microbial keratitis, a form of corneal inflammation, is over five times higher for those who sleep with their contacts in.
In addition to microbial keratitis, sleeping in contact lenses can also increase the risk of fungal keratitis, especially if there has been some form of eye trauma. Fungal keratitis can lead to vision loss in the infected eye if left untreated. Furthermore, poor contact lens hygiene, such as showering or swimming with lenses, can introduce harmful organisms into the eye, increasing the risk of infections like Acanthamoeba keratitis.
The consequences of sleeping with contact lenses can be severe and may result in permanent vision loss or blindness. It is crucial to practice good contact lens hygiene, including removing lenses before sleeping, to reduce the risk of eye infections and maintain eye health.

Dry eyes
As a result, corneal cells can become damaged, leading to various symptoms and complications. The eyes may feel dry and irritated upon waking, but this is more than just a minor inconvenience. The reduced oxygen supply impairs the cornea's ability to protect itself from microorganisms, making it easier for germs and bacteria to gain a foothold on the surface of the eye. This can lead to serious eye infections, with the risk of infection increasing by up to eight times.
One of the most common infections associated with contact lens wearers is microbial keratitis, an inflammation and infection of the cornea. Other types of infections include fungal keratitis and Acanthamoeba keratitis, which can develop from poor contact lens hygiene or a scrape in the eye. These infections can have severe consequences, potentially leading to permanent vision loss or blindness if left untreated.
To reduce the risk of dry eyes and infections, it is crucial to remove contact lenses before sleeping. If you accidentally fall asleep with your contacts in, remove them as soon as you wake up and switch to glasses for at least a day to give your eyes time to recover. Practicing good contact lens hygiene and following your eye doctor's directions for lens use are essential for maintaining eye health.
While it may be tempting to sleep with contact lenses in, especially during occasional naps or when feeling lazy, the risks of dry eyes and infections are significant. The best course of action is to make storing your contacts part of your bedtime routine and always have a backup plan, such as a pair of glasses, to give your eyes a break when needed.

Permanent damage to the cornea
Sleeping with contact lenses on can have adverse effects on the eyes, with one of the most severe being permanent damage to the cornea. The cornea, which is the protective dome on the surface of the eye, relies on oxygen from the atmosphere, which dissolves in the tear film that coats the eye. Contact lenses act as an extra barrier, reducing the amount of oxygen available to the cornea. This can lead to hypoxia, a state where there is not enough oxygen, causing corneal cells to get damaged.
Depriving the cornea of oxygen can cause it to swell, leading to irritation, blurred vision, or an infection. Repeated oxygen deprivation reduces the cornea's ability to regenerate cells, especially on its outer edges, which are crucial for protecting the eyes from invaders. This increases the risk of bacterial infections, with bacteria gaining access to the deeper layers of the eye.
Infections such as bacterial keratitis, caused by Staphylococcus aureus or Pseudomonas aeruginosa, can lead to permanent scarring of the cornea if left untreated. Another serious infection is fungal keratitis, which can result in permanent vision loss. Microbial keratitis, caused by the trapping of microorganisms against the cornea, is another potential issue.
Sleeping with contacts can also heighten the risk of corneal ulcers, where open sores form on the cornea, causing significant vision impairment or even permanent vision loss if not treated promptly. Therefore, it is essential to remove contact lenses before sleeping and practice good lens hygiene to prevent infections and reduce the risk of permanent corneal damage.

Allergic reactions
While it is rare, some people may experience an allergic reaction to the materials used in contact lenses or the ingredients found in contact lens solution.
Contact lenses are medical devices that should only be used according to your eye doctor's directions. Sleeping with contact lenses in your eyes can substantially increase the risk of eye infections, specifically microbial keratitis, which is the inflammation and infection of the cornea. The cornea of your eye relies on oxygen from the atmosphere, which dissolves in the tear film that coats your eye. When there isn't enough oxygen supply, corneal cells can get damaged, leading to various symptoms and complications.

You should monitor your eyes for any signs of infection and see an optometrist if you experience any eye-related symptoms.
In severe cases, infections caused by sleeping with contacts in can result in vision loss or blindness. However, it is important to note that the risk of infection is not limited to overnight wear, and proper contact lens hygiene practices, such as avoiding swimming or showering with contacts, are crucial to maintaining eye health.
