Abstract: Disclosed is a method for determining an optical system intended to equip a subject, the method including the steps of: —determining an index of sensitivity indicating, when the subject is placed in an environment including surfaces and/or borders forming globally a geometry of this environment; and landmarks associated with specific locations within the environment, how the subject relies on the global geometry and/or on the local landmarks of the environment to navigate within the environment; and—determining the optical system based on this index of sensitivity. The invention also relates to an ophthalmic lens and to an ophthalmic filter determined by such method.

Abstract: A method for determining at least one optical design parameter for a progressive ophthalmic lens intended to be fitted in a frame of a wearer, depending on the wearer's visual behaviour, includes: a) placing the wearer in a situation in which he carries out a visual task at a first working distance; b) during this task, determining at least two gaze directions of the wearer at this first working distance in a frame of reference of the wearer's head; c) determining a relative position of a surface related to the frame or to an ophthalmic lens intended to be fitted in the frame; d) determining for each gaze direction at the first working distance the intersection between this gaze direction and the surface so as to establish a map of these points of intersection on this surface; and e) deducing the sought-after optical design parameter from this map.

Abstract: Disclosed is a method including the steps of: a) illuminating a pupil of the eye of a subject by a light source; b) acquiring at least one picture of the pupil including an image of the reflection of the light source on the retina of the eye, by means of an image-capture apparatus; and c) and determining a refraction feature of the eye from at least a geometrical feature, a positional feature, or an intensity distribution of the image of the reflection of the light source. Optical distances between the pupil and, respectively, the light source and the image-capture apparatus, are different. An associated device is also described.

Abstract: Disclosed is a measurement method for determining a value of a visual correction need for near vision of an individual in a natural posture for near vision. A recognizing limit distance is determined so that the individual is able to recognize at least one predetermined symbol farther than the limit distance relatively to the individual and unable to recognize the at least one predetermined symbol closer to the individual than the limit distance. A portable medium displaying the predetermined symbol is displaced in front of the face and eyes of the individual to change a frontal distance between his/her eyes and the portable medium and in which when a recognizing limit distance is detected by the individual, the limit distance is measured and the value of the visual correction need is determined from the measured limit distance, wherein the visual correction need includes an accommodation compensation need.
