Optical image deflector assembly and method for locating visually sensitive peripheral areas of an eye, and determining corrective prismatic eye glasses therefore

摘要

A pair of rotatable optical image deflector assemblies are disclosed which are detachably mounted via an adapter bracket to a conventional eye testing apparatus. Each optical image deflector assembly has a fixed light reflecting optical element, and a pivotal reflecting optical element. The optical image deflector assembly directs light onto a peripheral area of an eye, and scans an arcuate portion of the area upon pivotal movement of the pivotal optical element.
