Contact lens wearers, beware: falling asleep with your lenses in—even for a short nap—could lead to serious eye health issues. Experts strongly advise against this common habit, as it greatly increases the chance of developing eye infections and potentially long-term vision damage.
The cornea, the eye’s clear front layer, depends on oxygen from the air for its health. Wearing contact lenses naturally limits the amount of oxygen reaching the cornea during daytime use. Leaving them in while asleep further restricts this oxygen supply, compromising the eye’s defense against bacteria and heightening the risk of infections.
Microbial keratitis, a bacterial infection of the cornea, stands out as one of the most severe complications of sleeping with contact lenses. If untreated, this condition can progress into a painful corneal ulcer, causing permanent scarring and possibly lasting vision loss. Even infrequent napping with lenses on can elevate this risk, prompting eye health professionals to issue strong warnings.
The good news is that such complications are largely avoidable with proper lens care. Specialists recommend removing contact lenses before any sleep, ensuring diligent lens hygiene, and adhering to the replacement schedule set by eye care providers. These steps can significantly mitigate risks associated with contact lens use.
Anyone noticing symptoms like redness, pain, light sensitivity, blurred vision, or sudden vision changes should seek immediate medical care. Quick intervention is crucial to preventing severe damage and preserving long-term eye health. While contact lenses are generally safe when used correctly, sleeping in them unnecessarily raises the likelihood of preventable eye issues.
