Eye health experts are sounding the alarm over the dangers of falling asleep while wearing contact lenses, a habit that can lead to severe eye infections and long-term vision issues. While it might seem harmless to doze off with lenses on, the risk of developing serious complications is significantly heightened, according to specialists.
The cornea, the eye’s clear front surface, requires oxygen from the air to maintain its health. Contact lenses naturally reduce the oxygen supply to the cornea during wear, and sleeping in them exacerbates this problem by further restricting oxygen intake. This oxygen deficit can weaken the eye’s natural defenses, making it more susceptible to bacterial infections.
One particularly severe condition linked to this practice is microbial keratitis, a bacterial infection of the cornea. If not treated promptly, this infection can escalate into a painful corneal ulcer, potentially causing permanent scarring and lasting vision loss. Experts emphasize that even occasionally napping with contact lenses can increase the likelihood of such infections.
Thankfully, these risks are largely preventable with diligent lens care. Eye specialists advise removing contact lenses before sleeping or taking naps, maintaining proper lens hygiene, and adhering to the replacement schedule provided by eye care professionals. These precautions can significantly reduce the chances of complications.
Individuals who experience symptoms like eye redness, pain, sensitivity to light, blurred vision, or sudden changes in eyesight are urged to seek medical attention without delay. Early treatment is crucial in preventing serious damage and safeguarding long-term vision. While contact lenses are generally safe when used correctly, sleeping in them unnecessarily raises the risk of avoidable eye health issues.
