An optometrist, Dan Dankyi, has explained why some people sleep with their eyes partially or completely open, warning that the condition could expose them to eye dryness, irritation and possible damage if left untreated.

The condition, medically known as nocturnal lagophthalmos, occurs when a person is unable to fully close their eyelids while sleeping.

According to a report by adomonline.com on November 11, 2026, Dankyi said the condition could be caused by abnormalities in the eyelids, muscles and nerves responsible for closing the eyes.

He explained that some people are naturally predisposed to the condition because of anatomical features that prevent their eyelids from closing completely.

“Others may develop it following injuries or underlying medical conditions affecting the eyelids and surrounding facial structures,” he noted.

Dankyi cautioned that sleeping with the eyes open should not be dismissed as a harmless habit, as prolonged exposure could leave the eyes dry and irritated, potentially resulting in damage.

He said treatment depends on the underlying cause and severity of the condition, with options including medication, lubricating eye drops and, in some cases, surgery.

The optometrist therefore urged people who notice that they sleep with their eyes partially or completely open to seek professional eye care for proper assessment and treatment.
