What You'll Learn
Increased risk of eye infection
Sleeping with contact lenses in your eyes can have several adverse effects, one of the most significant being the increased risk of eye infections. Leaving contact lenses in while sleeping can cut off the oxygen supply to your eyes, which can lead to various complications, including infections.
The cornea 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. During sleep, your eyes naturally produce fewer tears, further decreasing oxygen levels. This oxygen deprivation can cause corneal cells to become damaged, leading to issues such as irritation, blurred vision, and increased susceptibility to infections.
Contact lenses can also trap bacteria, fungi, and other microorganisms against the cornea, providing an ideal environment for them to multiply. This can result in microbial keratitis, an inflammation and infection of the cornea. Microbial keratitis is a serious condition that can lead to permanent scarring, vision loss, and even blindness if left untreated. Studies have shown that wearing contacts overnight increases the risk of microbial keratitis by more than five times, regardless of the type of lens used.
In addition to microbial keratitis, sleeping with contacts can also increase the risk of other eye infections. The Centers for Disease Control and Prevention (CDC) reports that sleeping in contacts can increase the risk of eye infections by six to eight times. These infections can lead to corneal damage, surgery, and, in rare cases, loss of vision. Acanthamoeba keratitis, for example, is a microbial eye infection that can occur if you sleep with your contacts and rinse them in tap water.
Furthermore, sleeping with contacts can increase the risk of fungal keratitis, especially in regions with mild and tropical weather. While most people who develop this infection experience some form of eye trauma, sleeping with contacts further increases the risk. Fungal keratitis can lead to blindness if left untreated.
In summary, sleeping with contact lenses can significantly increase the risk of eye infections, including microbial keratitis, fungal keratitis, and other serious infections that can lead to corneal damage, vision loss, and even blindness in severe cases. It is essential to follow the directions provided by your eye doctor and practice good contact lens hygiene to protect your eye health.

Oxygen deprivation
Oxygen is crucial to maintaining eye health. 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.
Contact lenses act as a barrier to oxygen, significantly reducing the amount of oxygen your eyes can access. This problem is exacerbated during sleep, as your eyes are closed, further reducing oxygen availability. Additionally, your eyes produce fewer tears during sleep, leading to dryness and irritation.
If you sleep with contact lenses in, you may experience corneal hypoxia, a condition that occurs when the cornea doesn't get enough oxygen. This can cause irritation, blurred vision, and an increased risk of infection. Repeated oxygen deprivation can also reduce the cornea's ability to regenerate cells, impairing its protective function and making it easier for bacteria to invade the deeper layers of the eye.
The consequences of oxygen deprivation can be severe. Serious eye infections can lead to corneal damage, surgery, and, in rare cases, permanent vision loss. Therefore, it is essential to remove contact lenses before sleep to allow your eyes to breathe and recover.
If you accidentally fall asleep with your contact lenses in, don't panic. Examine them in the mirror, and if they appear stuck, do not forcefully remove them as this can damage the cornea. Instead, try blinking to produce tears, which will help separate the contacts from your corneas. You can also apply a few drops of saline or eye drops to facilitate this process. Once the contacts feel normal again and are no longer stuck, it is safe to remove them.

Dry, sore, red eyes
Sleeping with contact lenses in your eyes can cause dry, sore, and red eyes. Contact lenses can absorb the moisture in your eyes, leading to dryness. This condition worsens when you sleep with your contacts in, as your eyes naturally produce fewer tears during sleep. Dry eyes can cause irritation, discomfort, and potential damage to the corneal surface.
Contact lenses that are too tight can restrict normal tear flow underneath the lenses. They also reduce the amount of oxygen getting to your corneas. Oxygen deprivation can cause the cornea to swell, leading to irritation, blurred vision, or an infection. Depriving the cornea of oxygen also reduces its ability to regenerate cells on its outer edges, which are crucial for protecting your eyes from bacteria.
Lenses that have not been cleaned properly can accumulate debris, which can get trapped under the lenses and cause further irritation and damage to the eyes. This is especially true if the lenses get dislodged or stuck in an unusual position while you sleep.
If you wake up with dry, sore, and red eyes after sleeping with your contacts in, it is important to let your eyes breathe and remove the lenses. Do not rip them out, as this could damage the cornea. Instead, blink a few times to get the tears flowing again, which will eventually separate the contacts from your corneas. You can also put a few drops of saline or eye drops into your eyes to help with removal.
If you experience dry, sore, and red eyes after sleeping with your contacts in, it is recommended to remove the contacts for several days and use over-the-counter lubricating eye drops or artificial tears to help your eyes recover.

Corneal damage
Sleeping with contact lenses can have severe consequences for the eyes, with one of the most common issues being corneal damage. The cornea, the transparent front part of the eye, relies on oxygen from the atmosphere, which dissolves in the tear film that coats the eye. When asleep, the eyes are closed, reducing the oxygen supply to the cornea. Contact lenses act as an extra barrier to oxygen, causing corneal hypoxia, a condition where the cornea does not receive enough oxygen. This can lead to corneal cells becoming damaged, resulting in various symptoms and complications.
The risk of corneal infections, such as microbial keratitis, increases significantly when sleeping with contact lenses. Keratitis is a severe infection of the cornea, often caused by bacteria, fungi, or amoebas. The lenses trap microorganisms against the cornea, creating an ideal environment for them to multiply. This can lead to serious health issues, including permanent corneal damage and potential vision loss.
In addition to infections, corneal dryness is a common issue when sleeping with contacts. Contact lenses absorb moisture from the eyes, leading to dryness, irritation, and discomfort. This can further cause potential damage to the corneal surface. It is crucial to remove the lenses as soon as possible upon waking and let the eyes recover before wearing lenses again.
Furthermore, corneal ulcers, which are open sores on the cornea, can also develop due to extended contact lens wear. The displacement of the lenses during sleep can cause scratches and injuries to the corneal surface, exacerbating the problem.
While it may be tempting to leave contacts in while sleeping, doing so can lead to serious corneal complications. It is essential to prioritize eye health and remove contacts before sleep to mitigate the risk of corneal damage and maintain healthy eyes.

Potential blindness
Sleeping with contact lenses in your eyes can lead to potential blindness in several ways. Firstly, it increases the risk of microbial keratitis, an infection of the cornea. Keratitis is often caused by bacteria, fungi, or amoebas, and it can lead to permanent vision loss and blindness if left untreated.
Secondly, contact lenses can deprive the cornea of oxygen, leading to corneal hypoxia. This oxygen deprivation can cause the cornea to swell, resulting in blurred vision and an increased risk of infection. Repeated oxygen deprivation can reduce the cornea's ability to regenerate cells, making it more vulnerable to bacterial infections that can cause permanent damage and vision loss.
Thirdly, contact lenses can trap moisture and provide an ideal environment for bacteria to multiply, leading to infections such as conjunctivitis and corneal ulcers. These infections, if left untreated, can result in serious complications, including vision loss and blindness.
Finally, regularly sleeping with contact lenses can lead to poor eye health and specific eye conditions, such as corneal ulcers and fungal keratitis, which can also result in vision loss and blindness if not treated promptly.
While it may be tempting to leave your contact lenses in while sleeping, the potential risks to eye health are significant. It is always best to remove contact lenses before sleeping and to practice good contact lens hygiene to prevent infections and maintain eye health.
