Visual psychophysics represent an invaluable way of studying the visual system aging process. First of all, the author considers the modifications induced by aging on the optic characteristics of the human eye. Subsequently, he outlines the specific reduction of visual acuity, contrast sensitivity, flicker fusion and color vision caused by optic nerve and visual pathway aging. He points to the role and importance of psychophysic investigations in the accurate definition of visual system aging.

Abstract
Visual psychophysics represent an invaluable way of studying the visual system aging process. First of all, the author considers the modifications induced by aging on the optic characteristics of the human eye. Subsequently, he outlines the specific reduction of visual acuity, contrast sensitivity, flicker fusion and color vision caused by optic nerve and visual pathway aging. He points to the role and importance of psychophysic investigations in the accurate definition of visual system aging.
