Aging causes laxity and downward shift of eyelid tissues and atrophy of the orbital fat. These eyespots could only sense ambient brightness: they could distinguish light and dark, but not the direction of the lightsource. Cone cells, conversely, need high light intensities to respond and have high visual acuity. Thus, for humans to be able to see while moving, the brain must compensate for the motion of the head by turning the eyes. Each sensor has its own lens and photosensitive
