A Visual Aid for Artists and Others with Retinitis Pigmentosa (‘Tunnel Vision’)

Tunnel vision resulting from retinitis pigmentosa is a severe handicap for artists, designers and draughtsmen. Composition and the interpretation of depicted material is difficult because only a portion of the material is visible at a time. Collaboration between an experimental psychologist and a practising artist afflicted with tunnel vision has produced two useful ways of effectively reducing the size of visual material, permitting more of it to be seen at a glance. One method uses a video camera and monitor; the other, a less expensive and optically superior method, uses two plane mirrors.
