Some people experience crusty eyelids in the morning due to a buildup of dried tears and oils while sleeping. This can be prevented by practicing good eye hygiene, such as washing the eyelids with a gentle cleanser before bed. To treat crusty eyelids effectively, using warm compresses and gentle eyelid scrubs can help remove the buildup and soothe the eyes. If the issue persists, it is recommended to consult with an eye doctor for further evaluation and treatment options.
