Eye health specialists are raising alarms over the dangers of falling asleep with contact lenses in place, even if it’s just for a short nap. While it might seem harmless, the practice can markedly elevate the risk of severe eye infections and other vision-related issues over time.
The cornea, which is the transparent front section of the eye, requires a steady supply of oxygen from the air for optimal health. Contact lenses, though convenient for vision correction, naturally restrict the amount of oxygen reaching the cornea during waking hours. This limitation becomes more pronounced if lenses are worn during sleep, further diminishing the oxygen supply and weakening the eye’s defense against bacterial infections.
One particularly grave consequence associated with sleeping in contact lenses is microbial keratitis, a bacterial infection of the cornea. Without timely intervention, this condition can progress to a painful corneal ulcer that risks leaving permanent scars and causing long-term vision impairment. Experts emphasize that even infrequent naps while wearing contact lenses can heighten this risk.
Thankfully, such complications can largely be avoided with proper care and attention to lens hygiene. Eye care professionals advise removing contact lenses before sleeping or napping, ensuring they are cleaned and stored correctly, and adhering to the replacement schedule provided by your eye care provider.
Individuals who notice symptoms like redness, discomfort, light sensitivity, blurred vision, or unexpected changes in eyesight should seek medical advice promptly. Early treatment is crucial in preventing significant damage and safeguarding long-term eye health. When used as directed, contact lenses are generally safe, but the unnecessary risk of complications from sleeping in them can be largely eliminated with precautionary measures.
