Abstract

An apparatus for determining optical parameters of a user with spectacles arranged in the use position on the head of the user includes at least one projection device designed and arranged for marking a partial region of the head of the user and/or of the spectacles of the user with a light projection; at least one image recording device designed and arranged for generating image data at least from the marked partial region of the head of the user and/or of the spectacles of the user; and a data processing device with a user data determining device, which is designed to determine user data from the marked partial region of the head and/or of the spectacles on the basis of the generated image data, wherein the user data comprise spatial information in the three-dimensional space of points of the partial region of the head and/or of the spectacles, and a parameter determining device, which is designed to determine optical parameters of the user on the basis of the user data.
