Visual Accommodation

Visual accommodation is a reflexive physical process in which the lens of the eye adjusts allowing images to become focused. These changes allow objects to be clear and in focus even when distances are changing. Visual accommodation is like a camera focusing on different points - it is a moving adjustment that puts into focus whatever is centered on at the moment. As you age the lens becomes less flexible and can't adjust as well leading to a loss of visual accommodation.
