Falling asleep with contact lenses on, even briefly, might seem insignificant, but experts in eye health caution against it due to the heightened risk of severe eye infections and potential long-term vision issues. The cornea, which is the transparent front part of the eye, depends on oxygen from the air to maintain its health. Contact lenses naturally restrict the oxygen supply to the cornea during the day, and wearing them while sleeping further exacerbates this limitation. This can compromise the eye’s protective barrier, making it more susceptible to bacterial infections.
One of the most serious risks associated with sleeping in contact lenses is microbial keratitis, a bacterial infection of the cornea. Without timely treatment, this condition can progress to a painful corneal ulcer, possibly leading to permanent scarring and long-term vision impairment. Experts emphasize that even occasional naps with contact lenses can increase this risk.
Thankfully, these complications are largely preventable with appropriate lens care. Eye specialists advise removing contact lenses before sleeping or napping, practicing good lens hygiene, and adhering to the replacement schedule recommended by your eye care provider.
Individuals experiencing symptoms such as eye redness, discomfort, sensitivity to light, blurred vision, or sudden vision changes should seek medical help immediately. Prompt intervention can prevent serious damage and safeguard long-term vision health.
When used as directed, contact lenses are generally safe. However, wearing them during sleep unnecessarily elevates the risk of avoidable eye complications.
