Abstract
The optical systems of an electro-optical instrument which measures the refractive error of human eyes are described. The analog printout enables one to read off the refractive correction as sphere, cylinder, and cylinder axis. The principle involved is a variation of the Foucault knife-edge test. Validation studies are summarized and various applications are briefly mentioned.
