More Information
Summary:A device for measuring the objective ocular refraction of a patient for a plurality of visual ranges, which includes a variable proximity optical sight system capable of selectively generating a first target and a second target and an image-capturing device having an optical measurement axis intended for being aligned with a line of sight of the patient, the image-capturing device being capable of capturing a first ocular refraction image when the first target is activated and a second ocular refraction image when the second target is activated. The image-capturing device and the optical sight system are arranged such that the optical measurement axis and the optical sight axis are arranged such that the optical measurement axis and the optical sight axis are contained in a single plane and the optical measurement axis is tilted at an angle alpha between +5 degrees and +85 degrees relative to the horizontal.
