摘要:
The present invention relates to a system (10) for determining the subjective refraction properties of an eye (20) of a test subject based on the use of a natural image (30), said system having the following: a memory (11) in which at least one natural image (30) is stored; a display device (12) for displaying the at least one natural image (30) from the memory (11); a lens arrangement (13) for adjusting various light-refracting elements (14, 15) in an optical path between the eye (20) of the test subject and the display device (12), wherein the lens arrangement (13) is arranged at a predefined distance (d) from the display device (12). The present invention further relates to a corresponding method and the use of a natural image (30) for refraction determination.
