The role of lighting

Abstract

The type and level of lighting affects the assessment and outcome of important functional elements of vision. The type and level of lighting affects the low vision individual selectively. Depending upon their personal visual condition, lighting impacts their visual acuity, their visual ergonomics, their field of vision available to the task and the stability of that field. By assessing the individual's lighting needs, it is possible to combine improved visual aids with lighting strategies to address specific personal tasks such as reading bills and writing checks. Examples are given of results obtained at the National Association for the Visually Handicapped.
