Abstract
In view of the problem of specifying an arrangement and a method by means of which an eye can be measured preferably without artifacts and quickly, an arrangement for measuring an eye (1), comprising a light source (2) which is suitable for emitting light rays (3, 4) to the cornea (5) of an eye (1) and a control unit (6) which drives the light source (2) to emit the light rays (3, 4) and is suitable for converting reflected light rays (3a, 4a, 4b) entering the arrangement into signals (7, 8), is characterized in that the light source (2) when driven by the control unit (6) emits a central light ray (3) and emits a plurality of peripheral light rays (4) which are radially offset with respect to the central light ray (3) or in that the light source (2) when driven by the control unit (6) emits a plurality of peripheral light rays (4) radially offset with respect to one another. Moreover, a method is specified.
