Sleeping with contact lenses in your eyes can lead to a number of issues. Your eyelids move during sleep, which can cause the lenses to shift out of place or get stuck. This can lead to scratches or other injuries to your eye. Contact lenses can also absorb the moisture in your eyes, leading to dryness, irritation, and redness. This condition can worsen when you sleep with your contacts in, as your eyes naturally produce fewer tears during sleep. Additionally, wearing contact lenses while you sleep increases the risk of eye infections, particularly microbial keratitis, which can cause vision loss and permanent scarring.

What You'll Learn
Increased risk of eye infections
Sleeping in your contact lenses can have several adverse effects on your eyes, one of the most common and serious being an increased risk of eye infections.
When you sleep with your contact lenses in, your eyes get deprived of the oxygen and hydration they need to fight off bacteria and microorganisms. This creates an optimal environment for bacteria to enter the eye area and cause infections. The risk of eye infections increases by six to eight times, according to the Centers for Disease Control and Prevention (CDC).
One common type of eye infection that can occur is bacterial keratitis, an infection of the cornea. It is generally caused by Staphylococcus aureus or Pseudomonas aeruginosa, both of which are bacteria commonly found on the human body and in the environment. Wearing contact lenses while sleeping increases the likelihood of bacterial keratitis by five times, according to studies. Acanthamoeba keratitis is another type of eye infection that contact lens wearers are at risk for, with 85% of those affected being contact lens wearers. Poor contact lens hygiene, such as swimming or showering with lenses on, further increases the risk of this infection.
Fungal keratitis is a serious eye infection that is most common in regions with mild and tropical weather. Sleeping with contacts increases the risk of this infection, which, if left untreated, can lead to blindness. Another possible infection is microbial keratitis, which can cause vision loss and permanent scarring.
In addition to these infections, sleeping in contact lenses can also lead to corneal ulcers, conjunctivitis (pink eye), and corneal hypoxia, a condition where the cornea does not receive enough oxygen.
While it is not uncommon for people to fall asleep with their contact lenses in, it is important to be aware of the potential risks and take the necessary precautions. Good contact lens hygiene and regular lens replacement are crucial to maintaining eye health and reducing the risk of infections.

Dryness and irritation
While sleeping with contact lenses in your eyes may not seem like a big deal, it can lead to several issues, including dryness and irritation.
Contact lenses are designed to sit on the surface of the eye, which means they can significantly reduce the amount of oxygen and moisture your eyes can access. When you sleep, this decrease in oxygen and hydration becomes even more severe. The cornea of your eye relies on oxygen from the atmosphere, which dissolves in the tear film that coats your eye. During sleep, your eyes naturally produce fewer tears, leading to dryness. This condition can be exacerbated by contact lenses, which can absorb moisture from your eyes. As a result, your lenses may become dehydrated and stuck to your corneas when you wake up.
In addition to dryness, reduced oxygen supply to the cornea can lead to irritation and discomfort. When there isn't enough oxygen, corneal cells can become damaged, causing blurred vision and an increased risk of infection. The cornea may also swell, leading to further irritation and inflammation.
If you wake up with dry and irritated eyes, it is important to handle the situation carefully. Before removing your contact lenses, evaluate the comfort of your eyes and check for signs of extreme dryness, irritation, or skin scratchiness. If your eyes are extremely dry or painful, it is recommended to moisturize them with sterile, lubricating eye drops to facilitate easier lens removal. Blink multiple times to evenly spread the moisture and help separate the contacts from your corneas.
While occasional overnight wear of contact lenses may not cause extensive damage, it is important to make it a habit to always remove your contacts before sleeping. Good contact lens hygiene, including proper cleaning and adhering to recommended wear schedules, is crucial to maintaining eye health and preventing infections.

Potential corneal damage
Sleeping with contact lenses on can lead to corneal damage, which can result in permanent vision loss. The cornea, which is the front surface of the eye, relies on oxygen from the atmosphere, which dissolves in the tear film that coats the eye. When there isn't enough oxygen supply, corneal cells can get damaged, leading to various symptoms and complications. This condition is called hypoxia, where the cornea does not get enough oxygen.
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 on its outer edges, which are crucial for protecting the eyes from invaders. This increases the risk of bacteria entering the deeper layers of the eye and causing infections.
The risk of microbial keratitis, a form of corneal inflammation caused by infection, is over five times higher when wearing contact lenses overnight. Bacterial keratitis is an infection of the cornea, generally resulting from either Staphylococcus aureus or Pseudomonas aeruginosa, both of which are bacteria commonly found on the human body and in the environment. Acanthamoeba keratitis, another type of corneal infection, is also associated with contact lens use, with 85% of cases occurring in contact lens wearers. Poor contact lens hygiene, such as swimming or showering with lenses on, further increases the risk of this infection.
In addition to infections, corneal ulcers can develop as a result of sleeping with contact lenses. Ulcers can lead to serious eye complications and permanent vision loss if not properly treated. Therefore, it is essential to practice good contact lens hygiene and always remove lenses before sleeping to reduce the risk of corneal damage and other eye health issues.

Ulcers and other issues
Although accidentally falling asleep in your contact lenses occasionally is not a major concern, making a habit of sleeping in them can have serious consequences for your eyes.
Sleeping in contact lenses can lead to corneal ulcers, conjunctivitis (pink eye), and corneal hypoxia, a condition where the cornea does not receive enough oxygen. Depriving the cornea of oxygen can cause it to swell, leading to irritation, blurred vision, and an increased risk of infection. The cornea's ability to regenerate cells on its outer edges is also reduced, impairing its ability to protect the eye from bacteria and other microorganisms.
Extended-wear contact lenses can increase the risk of bacterial keratitis, an infection of the cornea, as well as fungal keratitis, which is a leading cause of blindness in India. Acanthamoeba keratitis, an inflammation of the cornea, is also more common in contact lens wearers, with 85% of cases occurring in this group.
In addition to the risk of infection, sleeping in contact lenses can cause eye dryness, irritation, and discomfort. This is because the eyes produce fewer tears during sleep, and contact lenses can absorb moisture from the eyes, leading to dryness and irritation.
To avoid these issues, it is recommended to always remove contact lenses before sleeping and to practice good contact lens hygiene.

Acanthamoeba keratitis
Sleeping with contact lenses in can be dangerous and can increase the risk of eye infections. The contact lenses can absorb the moisture in your eyes, leading to dryness. This condition can worsen when you sleep with your contacts in, as your eyes naturally produce fewer tears during sleep.
To reduce the risk of AK, contact lens wearers should practice good lens hygiene, including washing hands before handling lenses, removing lenses before showering or swimming, and cleaning lenses with appropriate solutions. It is also important to replace the contact lens case with a new solution rather than topping off the old solution.
If you accidentally sleep with your contacts in, it is recommended to remove them as soon as possible, use eye drops, and let your eyes rest. While occasional overnight wear may not cause extensive damage, it is important to make it a habit to remove contacts before sleeping to maintain eye health.
