Contact lens wearers are being cautioned by eye health experts about the dangers of falling asleep with their lenses in place, even for short naps. This seemingly harmless habit can sharply increase the likelihood of developing serious eye infections and potentially long-term vision issues.
The cornea, the transparent front part of the eye, depends on oxygen from the air to maintain its health. During the day, contact lenses naturally decrease the oxygen supply to the cornea. Wearing them while sleeping exacerbates this reduction, compromising the eye’s protective barrier and making it more susceptible to bacterial infections.
One of the most severe risks associated with sleeping in contact lenses is microbial keratitis, a bacterial infection of the cornea. If not addressed promptly, this condition can progress into a painful corneal ulcer, potentially leading to permanent scarring and long-term vision impairment. Experts emphasize that even infrequent naps with contact lenses can elevate this risk.
Fortunately, such complications are largely preventable with diligent lens care. Specialists advise removing contact lenses before sleeping or taking naps, adhering to good hygiene practices, and following the replacement schedule recommended by your eye care provider.
Individuals who notice symptoms like eye redness, pain, sensitivity to light, blurred vision, or sudden changes in vision should seek medical attention without delay. Timely treatment can avert serious damage and safeguard long-term eye health. Though contact lenses are safe when used correctly, sleeping in them unnecessarily increases the risk of avoidable eye problems.
