Eye health experts are issuing a stern warning about the risks associated with falling asleep while wearing contact lenses, even if it’s just for a short nap. This seemingly innocuous habit can substantially increase the likelihood of developing severe eye infections and may lead to long-term vision issues.
Contact lenses inherently reduce the amount of oxygen that reaches the cornea, the transparent front part of the eye essential for clear vision. During the day, this reduction is manageable; however, wearing lenses while asleep further restricts oxygen supply, potentially compromising the eye’s natural defense mechanisms. This increased vulnerability can pave the way for bacterial infections.
Among the most concerning conditions linked to this practice is microbial keratitis, a bacterial infection that affects the cornea. If not promptly addressed, this infection can evolve into a painful corneal ulcer, resulting in permanent scarring and potentially irreversible vision loss. Experts emphasize that even infrequent naps with contact lenses in can elevate the risk of such infections.
The good news is that these serious complications can largely be avoided with diligent lens care. Eye care professionals advise removing contact lenses before sleeping or napping, adhering to proper lens hygiene practices, and following the prescribed replacement schedule. Such precautions can significantly mitigate the risks.
Individuals who experience symptoms like eye redness, discomfort, sensitivity to light, blurred vision, or sudden changes in eyesight are urged to seek medical attention without delay. Early intervention can prevent severe damage and safeguard long-term vision. While contact lenses are generally safe when used appropriately, the unnecessary risk of sleeping in them should be avoided to prevent possible eye health complications.
