Eye health experts caution against sleeping with contact lenses on, emphasizing that even short naps can heighten the risk of severe eye infections and long-term vision issues. The cornea, which is the transparent front part of the eye, depends on oxygen from the air to stay healthy. Contact lenses naturally block some of this oxygen during daytime wear, and keeping them on while sleeping further reduces the oxygen supply to the cornea. This reduction weakens the eye’s protective barrier, increasing the susceptibility to bacterial infections.
One of the most serious risks associated with sleeping in contact lenses is microbial keratitis, a bacterial infection that affects the cornea. If this condition goes untreated, it can lead to the formation of a painful corneal ulcer, potentially resulting in permanent scarring and lasting vision impairment. Experts warn that even infrequent naps with contacts can elevate this risk significantly.
Preventing these complications is largely achievable with proper care and practices. Eye specialists advise removing contact lenses before sleeping or napping, upholding rigorous lens hygiene, and adhering to the replacement schedule recommended by eye care professionals. These precautions can significantly reduce the likelihood of encountering serious eye health issues.
Individuals who notice symptoms such as redness, pain, sensitivity to light, blurred vision, or sudden changes in eyesight should seek medical attention promptly. Early intervention is essential to preventing severe damage and ensuring long-term vision protection.
While contact lenses are generally safe when used correctly, sleeping in them unnecessarily increases the risk of avoidable eye complications. Therefore, maintaining proper lens care and usage practices is crucial to safeguarding eye health.
