While it might seem harmless to take a quick nap with contact lenses on, eye health experts caution against this habit. They emphasize that even brief periods of sleep with contact lenses can substantially elevate the risk of severe eye infections and permanent vision issues.
The cornea, which is the transparent front part of the eye, relies on oxygen from the surrounding air to maintain its health. During the day, contact lenses naturally restrict the amount of oxygen that reaches the cornea. Sleeping with lenses further diminishes this oxygen supply, potentially compromising the eye’s protective barrier and creating an opportunity for bacteria to invade and cause infections.
One major concern associated with sleeping in contact lenses is microbial keratitis, a bacterial infection that affects the cornea. If this condition is not treated promptly, it can progress into a painful corneal ulcer, possibly resulting in permanent scarring and lasting vision impairment. Experts warn that even infrequent naps with lenses can increase the likelihood of developing such complications.
Fortunately, these risks can be minimized with appropriate lens care practices. Eye specialists advise removing contact lenses before going to sleep or even taking short naps. They also recommend maintaining proper lens hygiene and adhering to the replacement schedule prescribed by eye care professionals.
Individuals who notice symptoms like eye redness, discomfort, sensitivity to light, blurred vision, or any sudden changes in their eyesight are urged to seek medical attention without delay. Early intervention can help avert serious damage and safeguard long-term vision. While contact lenses are generally safe when used correctly, sleeping with them unnecessarily raises the chances of preventable eye issues.
