摘要： The invention relates to a method for determining a value of a global sensitivity parameter of a subject, said global sensitivity parameter being relative to the sensitivity of said subject to a variation of at least an optical feature of at least an ophthalmic lens placed in front of at least one eye of said subject, comprising the following steps:
a) determining (100) a single value of at least a first sensitivity parameter of said subject, relative to the sensitivity of the subject to a variation of a first optical feature of at least a first ophthalmic lens,
b) determining (110) a single value of at least a second sensitivity parameter of said subject, relative to the sensitivity of the subject to a variation of a second optical feature of at least a second ophthalmic lens,
c) determining (120) said value of the global sensitivity parameter taking into account a combination of said single values of the first and second sensitivity parameters.
It also related to methods using this value and a system for performing this method.-

摘要： The invention concerns a couple of test images, for a binocular refraction method, that comprises:
- a first test image (21) to be provided to a first eye of a subject, comprising a central image (21c) surrounded by a first peripheral image (21p), this central image comprising at least one optotype (210); and
- a second test image (22) to be provided to a second eye of the subject, comprising a central image (22c) surrounded by a second peripheral image (22p) substantially identical to the first peripheral image, this central image being deprived of optotypes, or comprising only optotypes (22o) with a low contrast or sharpness level.
The invention concerns also an associated binocular refraction method and refraction instrument, and an associated computer program.-

摘要： The invention relates to a system for determining a rounded value of an optical feature of at least an ophthalmic lens adapted to provide a dioptric correction for improving the vision of a subject, said system comprising one or more processors programmed to implement the steps of:
a) determining (400) a first test value of the optical feature and a first variation increment of the optical feature,
b) performing (500) a first trial of said subjective test wherein two first different optical situations are determined based on at least the first test value,
c) determining (600) a second test value of the optical feature based on the first test value, on the first variation increment and on the result of the first trial,
d) performing (700) a second trial of said subjective test wherein two second different optical situations are determined based on at least the second test value,
e) determining (800) an intermediary value of the optical feature based on the result of the first trial and on the result of the second trial,
f) determining (900) said rounded value of the optical feature by rounding said intermediary value to a reference value, said rounding modifying the dioptric correction of said ophthalmic lens by less than a predetermined basic dioptric value.-

摘要： The invention relates to a method for determining a filter for an ophthalmic lens to be placed in front of the eye of the wearer, said filter being able to improve or maintain the visual comfort and/or the visual performances of said wearer. According to the invention, the determination method comprises: a step of measuring a variable representative of sensitivity of the eye or both eyes of the wearer to a characteristic light flow, and a step of determining at least one optical characteristic of said filter according to the representative variable measured.

摘要： The invention relates to a system for determining a value of a magnitude associated with a subjective value of an optical feature of at least a corrective lens adapted to an eye of a subject, by implementing a subjective test where the subject is asked to describe his visual performance in a plurality of real optical conditions by choosing one descriptive answer among a set of possible descriptive answers, comprising a computer with one or more memory and one or more processor, wherein:
- an initial model giving the probability of each descriptive answer of the set of descriptive answers for each theoretical optical condition of a plurality of theoretical optical conditions is stored in one of said one or more memory of said computer,
- said one or more processor of said computer is programmed to:
a) collect (500) the results of said subjective test, performed by asking the subject to describe his visual performance in each real optical condition of said plurality of real optical conditions by choosing, for each real optical condition, one descriptive answer among said set of possible descriptive answers, said results comprising each descriptive answer chosen and the corresponding real optical condition,
b) determine (800, 900) the value of said magnitude by taking into account said initial model and each descriptive answer collected.
