Preventative Vision CareVision, in the broadest sense, is the global ability of the brain to extract, process and act on information presented to the eye. This complex process can be thought of as three major but related areas: visual acuity, which is largely dependent upon refractive status and eye health; visual efficiency skills, representing eye focusing, teaming, and tracking skills; and visual information processing, representing the ability to recognize and discriminate visual stimuli and to interpret them correctly based upon previous experience. Every examination we provide, regardless of age, has these thoughts in mind.
