Most people close their eyes when they sleep, but some individuals sleep with their eyes partially or completely open. While it may seem unusual, sleeping with your eyes open is a real condition that affects children and adults.
Known medically as nocturnal lagophthalmos, sleeping with your eyes open may be harmless for some people. However, in others, it can lead to eye irritation, dryness, and discomfort that affects sleep quality.
Understanding why this happens and when it requires attention can help protect your eye health and improve nighttime comfort.
