Abstract: Disclosed is a method for determining a specific near vision power of an ophthalmic lens to be provided to a wearer having an ophthalmic prescription, the specific near vision power being for near distance vision, the method including: an ophthalmic lens providing step during which at least an ophthalmic lens having a near distance vision zone including a mean power adapted for near distance vision is provided to the wearer; a near vision task speed determining step during which the processing speed of a near vision task by the wearer when wearing the provided ophthalmic lens is determined; wherein the ophthalmic lens providing step and the near vision task speed determining step are repeated with ophthalmic lenses having different mean power, so as to determine a specific near vision power corresponding to the mean power providing an improved near vision task processing speed.

Abstract: Disclosed is a method for measuring the refraction of an individual by a refraction measuring appliance, including: an initial step of determining at least one initial value of a visuo-postural parameter of the individual; a step of processing the initial value in order to deduce at least one initial value of a regulating parameter of the refraction measuring appliance, the regulating parameter being associated with the visuo-postural parameter; a step of regulating the refraction measuring appliance according to the initial value of the regulating parameter; and a step of measuring the refraction of the individual by the measuring appliance regulated in this way. Also disclosed is a method for the optical design of an ophthalmic lens, and to a pair of glasses including such a lens.

Abstract: A method for determining a dioptric parameter includes: first, a test optical element having a dioptric function having a specific value of the dioptric parameter to be determined is provided and the person looks at a visual target using the test optical element; second, evaluation data and certitude data are collected, the evaluation data being indicative of the visual assessment expressed by the person looking at the visual target using the test optical element and certitude data being indicative of the degree of certainty of the person upon expressing the visual assessment. The first and second steps are repeated by varying the value of the dioptric parameter. For each value of the dioptric parameter tested a value a degree of certainty of the person is determined. The value of the dioptric parameter of the person is determined based on the values of degree of certainty of the person.

Abstract: A method for determining optical power of an optical lens to be placed in front of an eye of a person, the method including: a first distance determining during which a first gazing distance is determined, which is the distance between the eye of the person and a first visual stimulus when the person gazes at the first visual stimulus in a given gazing direction with a first level of attention: a second distance determining during which a second gazing distance is determined, which is the distance between the eye of the person and a second visual stimulus when the person gazes at the second visual stimulus in the given gazing direction with a second level of attention different from the first level of attention; and an optical power determining during which the optical power adapted for the person is determined based on the first and second gazing distances.
