Eye health experts are issuing a warning about the dangers of sleeping in contact lenses, even during short naps. This common habit can greatly elevate the risk of serious eye infections and long-standing vision issues. The cornea, which is the clear front surface of the eye, depends on oxygen from the air to remain healthy. Contact lenses inherently restrict the amount of oxygen reaching the cornea throughout the day, and wearing them while sleeping exacerbates this restriction. This reduced oxygen supply can weaken the eye’s protective barrier, making it more susceptible to bacterial infections.
One of the most severe complications associated with this practice is microbial keratitis, a bacterial infection of the cornea. Without timely treatment, this condition can evolve into a painful corneal ulcer, which may cause permanent scarring and lead to lasting vision impairment. Experts emphasize that even infrequent naps with contact lenses in place can increase the likelihood of developing such infections.
The good news is that these complications can be largely avoided by adhering to proper lens care practices. Eye care professionals advise removing contact lenses before sleeping or napping, maintaining diligent lens hygiene, and following the recommended replacement schedule provided by your eye care provider. These steps are crucial in safeguarding eye health and preventing unnecessary complications.
Individuals who experience symptoms like eye redness, discomfort, light sensitivity, blurred vision, or sudden changes in eyesight are encouraged to seek immediate medical attention. Prompt intervention can prevent serious damage and help preserve long-term vision. While contact lenses are generally safe when used correctly, the risks associated with sleeping in them are significant and can lead to avoidable eye health issues.
