Eye health experts are highlighting the risks associated with falling asleep while wearing contact lenses, noting that even short naps can considerably increase the likelihood of developing serious eye infections and potentially long-term vision issues. The cornea, which is the transparent front part of the eye, depends on oxygen from the air to maintain its health. Contact lenses naturally reduce the oxygen supply to the cornea during wear, and sleeping with them on exacerbates this effect, further restricting oxygen access. This reduction can compromise the eye’s defense against infections, making it more susceptible to bacterial invasion.
A significant concern linked to sleeping in contact lenses is microbial keratitis, a bacterial infection affecting the cornea. If not promptly treated, this infection can progress into a painful corneal ulcer, possibly leading to permanent scarring and irreversible vision loss. Experts emphasize that even infrequent naps with lenses in the eyes can elevate this risk, underscoring the importance of adhering to proper lens care practices.
Thankfully, the complications associated with sleeping in contact lenses are largely avoidable. Eye care professionals advise removing lenses before sleeping or napping, practicing diligent lens hygiene, and following the recommended replacement schedule prescribed by an eye care provider. Such measures significantly mitigate the risks of developing infections and other complications.
Individuals who experience symptoms like eye redness, pain, sensitivity to light, blurred vision, or sudden changes in eyesight should seek medical attention without delay. Early intervention can prevent severe damage and help safeguard long-term vision. While contact lenses are considered safe for use when guidelines are followed, wearing them during sleep unnecessarily heightens the risk of preventable eye complications.
