condition that causes one to sleep with eyes partially open
Lagophthalmos is defined as a condition where oneâs eyelids canât close enough to cover the eye completely. The term nocturnal lagophthalmos is used to describe the condition when it occurs while youâre sleeping.
Lagophthalmos is defined as the inability to close the eyelids completely. Blinking covers the eye with a thin layer of tear fluid, thereby promoting a moist environment necessary for the cells of the exterior part of the eye. The tears also flush out foreign bodies and wash them away.
