METHOD FOR DETERMINING OPTICO-PHYSIOGNOMIC PARAMETERS OF A USER WITH A CERTAIN MEASURING ACCURACY IN ORDER TO MATCH SPECTACLE LENSES TO SUIT THE USER FOR NEAR VISION

摘要

The invention relates to a method for determining optico-physiognomic parameters of a user (1) with a certain measuring accuracy in order to match spectacle lenses to suit the user (1) for near vision, using an electronic image capturing device (7) and a data processing device (4), the electronic image capturing device (7) being placed centrally in front of the user (1) in the reading position, at least the facial region of the user (1) fitted with the spectacle frame (2) being photographically captured by the electronic image capturing device (7) and the geometrically-physiognomic parameter being calculated by evaluating the image which has been captured from the front. According to the invention, at least two optical signals (11, 12, 13) are produced in temporal succession and at different reading levels between the face of the user and the image capturing device (7) in the vertical plane running through the optical axis (8) of the image capturing device (7), such that the gaze direction of the eyes is directed to the optical signals (11, 12 13). Once the eyes are fixed to the optical signal (11, 12, 13) at the respective reading level, the electronic image capturing device (7) is triggered and at least one parameter which is relevant for near vision is calculated from the at least two images.
