Carl Friedrich Richard FörsterCarl Friedrich Richard Förster (November 15, 1825 - July 7, 1902) was a German ophthalmologist who was born in the town of Lissa (today Leszno, Poland). He received his medical doctorate in 1849, and for most of his career was associated with the University of Breslau. Two of his assistants at Breslau were Hermann Wilbrand (1851-1935) and Hermann Rudolph Aubert (1826-1892). Additional recommended knowledgeFörster is remembered primarily for his tests of visual acuity; particularly research of indirect vision and visual field boundaries. From these tests, the eponymous terms of Förster's perimeter and Förster's shift are derived. He also devised a specialized photometer to determine the smallest amount of light that will permit an object to be visible. In 1871 Förster defined the difference between negative and positive scotoma (blind spot); if vision of the scotoma region is a void, it is a negative scotoma, and if the blind spot is an area of darkness/lightness or comprised of hallucinatory patterns, it was called a positive scotoma.
