The present invention relates to an apparatus 10 and method for measuring the individual data of the spectacle (14) is arranged in the measurement position, the glasses have the left and / or right spectacle lens (16, 18). According to the invention, the device 10 includes a display 24 for displaying the test structure (25). The apparatus 10 includes a left eyeglass lens 16 and / or the image-capturing device 26 to capture the test structure 25 to the imaging beam path through the right spectacle lens 18 of the eyeglasses 14 . Device 10 is a left eyeglass lens 16 and / from the known spatial position of the display 24 of the image and the image capturing device 26 of the test structure (25) is captured by the image capturing device 26 or it comprises a computer unit (82) at least with a computer program for determining a power distribution of a portion of the right spectacle lens (18). Glasses (14) are arranged at the measurement location to measure the individual data of the spectacle (14). Then in accordance with the present invention, there is provided a test structure (25). Then, the image of a test structure 25 is imaged through the left and / or right spectacle lens (16, 18) of the spectacles (14) are arranged at the measurement position is captured by the beam path. Then, the refractive power distribution of the left eyeglass lens 16 and / or the right spectacle lens 18 is determined from the captured image of the coordinates and test structures 25 of the test structure (25).
