Astronomers and pilots have known for a long time that closing one eye can preserve vision in that eye while going from dark to light and back. Recently, it was reported that viewing a smartphone monocularly in an otherwise dark room can lead to transient, but strong reductions in retinal sensitivity in that eye (Alim-Marvasti, Bi, Mahroo, Barbur, & Plant, 2016). But seeing detail is not the only function that is mediated by the retina. Here, we address the question whether light exposure to one eye only (monocular) has tangible effects on the suppression of melatonin by light, relative to both eyes open (binocular).
