Wearing contact lenses while sleeping, even during a short nap, can pose significant risks to eye health, according to experts. They emphasize that this habit can lead to serious infections and potentially long-term vision issues. The cornea, which is the clear front layer of the eye, depends on oxygen from the air to maintain its health. Contact lenses inevitably reduce the amount of oxygen reaching the cornea during normal wear, and keeping them on during sleep exacerbates this reduction. This oxygen deprivation can compromise the eye’s protective barrier, making it more susceptible to bacterial infections.
Among the most severe conditions associated with sleeping in contact lenses is microbial keratitis, a bacterial infection affecting the cornea. If not promptly treated, microbial keratitis can progress to a painful corneal ulcer, which can cause permanent scarring and potentially lead to lasting vision loss. Eye health professionals warn that even infrequent naps with contact lenses can elevate the risk of such infections.
Fortunately, these eye health complications can largely be avoided through proper lens care. Specialists strongly advise removing contact lenses before any sleep, whether it is at night or just a brief nap. Maintaining good lens hygiene and adhering to the replacement schedule provided by one’s eye care professional are also crucial steps in preventing infections.
Individuals who experience symptoms such as redness, pain, light sensitivity, blurred vision, or sudden changes in eyesight should seek immediate medical attention. Early treatment is essential in preventing severe damage and ensuring the protection of long-term vision health.
While contact lenses are generally safe when used as directed, sleeping in them increases the likelihood of avoidable eye complications. By following recommended practices, users can enjoy the benefits of contact lenses without compromising their eye health.
