Eye health experts are cautioning against the habit of falling asleep while wearing contact lenses, even if it’s just for a short nap. This seemingly harmless action can significantly increase the risk of developing serious eye infections and long-term vision issues. The cornea, which is the transparent front part of the eye, requires a sufficient supply of oxygen from the air to maintain its health. During the day, contact lenses naturally reduce the amount of oxygen that reaches the cornea. When worn during sleep, the oxygen supply is further diminished, potentially compromising the eye’s protective barrier and making it more susceptible to bacterial infections.
Among the most severe complications that can arise from sleeping with contact lenses is microbial keratitis, a bacterial infection that targets the cornea. If not promptly treated, this condition can escalate into a painful corneal ulcer, leading to permanent scarring and potentially causing lasting vision loss. Experts emphasize that even the occasional nap while wearing contact lenses can elevate this risk, underscoring the importance of adhering to safe lens practices.
Proper lens care is crucial to preventing these complications. Specialists advise removing contact lenses before sleeping or napping, maintaining rigorous lens hygiene, and following the replacement schedule recommended by eye care professionals. These practices can significantly reduce the likelihood of infections and other adverse effects.
Individuals who notice symptoms such as redness, pain, sensitivity to light, blurred vision, or any sudden changes in their eyesight are urged to seek immediate medical attention. Early intervention can help avert serious damage and safeguard long-term vision. While contact lenses are generally safe when used correctly, the unnecessary risk associated with sleeping in them can lead to avoidable eye complications.
