ABSTRACT:
An ophthalmological apparatus is arranged in such a manner that different measuring light sources are provided for an eye refractive power measuring system and a lens refractive power measuring system. A light sensor of the lens refractive power measuring system is commonly used as at least either the light sensor for an alignment observing system or the light sensor for the eye refractive power measuring system. A lens to be examined can be placed at a position which is different from a position where an eye to be examined is placed.
