Abstract (en)
[origin: CA2963584A1] The invention relates to a 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, using an electronic image capturing device disposed centrally in front of the user and a data processing device. At least two optical signals are produced in temporal succession and at different reading levels between the face of the user and the image capturing device in a vertical plane running through the optical axis of the image capturing device, such that the gaze direction of the user's eyes is directed to the optical signals in succession. Once the user's eyes are fixed to the optical signal at each reading level, the electronic image capturing device is triggered and an image is captured. At least one parameter that is relevant for near vision is calculated from at least two captured images.
