Eyelid closure causes myopia in humans

Eyelid closure causes myopia in humans

D J O'Leary et al. Experientia. .

Abstract

Humans with unilateral ptosis are more myopic in the closed eye than in the normal eye. The effect seems unrelated to visual loss. In pairs of humans ranked for sleep and myopia, the more myopic tends to sleep the more. We conclude that eyelid closure causes myopia.
