Eye health experts are cautioning against the common habit of falling asleep with contact lenses on, highlighting the significant risk it poses for serious eye infections and potential long-term vision issues. Although a brief nap with lenses may seem trivial, it can have profound effects on eye health.
The cornea, which is the transparent surface at the front of the eye, depends on oxygen from the environment to remain healthy. Contact lenses naturally restrict the amount of oxygen reaching the cornea throughout the day. Sleeping with them further diminishes this oxygen supply, potentially compromising the eye’s protective barrier. This weakened state increases vulnerability to bacterial infections.
One of the most severe conditions associated with sleeping in contact lenses is microbial keratitis, a bacterial infection of the cornea that can escalate into a painful corneal ulcer if not treated promptly. This ulcer can lead to permanent scarring and even lasting vision impairment. Experts emphasize that even infrequent naps with contact lenses can elevate this risk.
Fortunately, these risks can be mitigated through conscientious lens care practices. Eye specialists advise removing contact lenses before sleeping or napping, adhering to strict lens hygiene, and following the replacement schedule recommended by eye care professionals.
Individuals experiencing symptoms such as redness, discomfort, sensitivity to light, blurred vision, or sudden changes in eyesight should seek immediate medical attention. Early treatment can prevent serious damage and help preserve long-term vision. While contact lenses are generally safe when used correctly, sleeping in them raises the likelihood of avoidable complications.
