Eye health specialists are raising alarms about the potential dangers of falling asleep with contact lenses in place, even for brief periods. What might appear as an innocuous habit can actually lead to a significantly heightened risk of developing severe eye infections and long-term vision impairment.
Oxygen is crucial for the cornea, the transparent front part of the eye, to maintain its health. During regular use, contact lenses already restrict the cornea’s access to oxygen from the air. When lenses are worn during sleep, this oxygen supply is further diminished, which can weaken the eye’s natural defenses and create an environment where bacteria can thrive and cause infections.
Among the most severe issues associated with sleeping in contact lenses is microbial keratitis, a bacterial infection that affects the cornea. If not promptly addressed, this condition can escalate into a painful corneal ulcer, potentially leading to permanent scarring and irreversible vision loss. Experts emphasize that even infrequent naps with lenses in can elevate the risk of such infections.
Fortunately, these risks can largely be mitigated through proper lens care practices. Eye care professionals advise removing contact lenses before sleeping or napping, maintaining rigorous hygiene with lenses, and adhering to the replacement schedule prescribed by one’s eye care provider. These practices are crucial in preventing complications.
Individuals who notice symptoms like redness, pain, sensitivity to light, blurred vision, or sudden changes in eyesight should seek immediate medical care. Timely intervention is key to preventing serious damage and preserving long-term vision. While contact lenses are generally safe when used as directed, wearing them to sleep unnecessarily increases the risk of avoidable eye complications.
