The eyes do not possess the same self-healing capabilities as skin, meaning damage can be prolonged or permanent. Some eye conditions stem from daily habits, such as wearing contact lenses overnight.

While sleeping, the amount of tears and oxygen reaching the cornea decreases. Wearing contact lenses further restricts oxygen flow. This oxygen deprivation weakens the corneal surface, making it prone to cracks and increasing the risk of bacterial keratitis.

Contact lens-related eye infections often present with mild initial symptoms. Patients may experience redness, discomfort, or itching, which can be mistaken for dry eyes or fatigue, leading them to continue wearing lenses. However, bacterial keratitis can progress rapidly within hours and become severe.

At this stage, delayed treatment can lead to long-term corneal damage. This condition requires early medical intervention to limit the risk of vision impairment. In severe cases, infection can cause deep corneal damage.

Removing lenses before sleep is a simple yet effective habit for eye protection. Additionally, thorough hand washing, proper storage, timely lens replacement, and avoiding water contact significantly reduce the risk of infection. If you accidentally fall asleep wearing contact lenses, do not remove them immediately; they may be dry and sticky, causing discomfort. Apply artificial tears or gently massage your eyelids to moisten them, then slowly slide the lens out, avoiding forceful removal. After removal, avoid wearing contact lenses for the rest of the day if possible.

Warning signs of an eye infection requiring medical attention include persistent eye redness after removing contact lenses, significant pain or discomfort, blurred vision, light sensitivity, and abnormal discharge.
