VISION - A BEHAVIOURAL OPTOMETRIC VIEWPOINT

Vision in Vehicles meetings have dealt with the relationships between how a person uses data from their lighted environment to drive their vehicle. No specific definition of vision has been put forth or accepted by this group. Vision requirements for vehicle operators emerge from a particular model of what vision is. This presentation shares some definitions used by behavioural optometrists. Vision is a very complex, highly parallel processing activity involving nearly every part of the human being. The author uses the four-circle concept first introduced by Skeffington as a way of explaining his understanding of vision. The four circles are described: antigravity; centering; identification; and communication. The eye selectively reacts to a very narrow band of the electromagnetic spectrum which means that much potential information is lost. A major goal of good vision care is to allow the person simultaneously to take in and more fully process more information from more of their world. (A) For the covering abstract see ITRD E106152.
