Abstract: It is proposed a method for defining a design of an ophthalmic tinted lens provided with a turquoise blue ophthalmic filter. It is provided at least one optical parameter value that is prescribed with reference to a clear ophthalmic lens. At least one non-null optical power value is determined from said at least one prescribed optical parameter value. At least one reduction value is obtained. At least one reduced optical power value is calculated in function of said at least one non-null optical power value and said at least one reduction value. The ophthalmic tinted lens design is defined on the basis of said at least one reduced optical power value. Methods for defining a design of a first and a second ophthalmic tinted lens are also proposed. It is also proposed a corresponding ophthalmic tinted lens.

Abstract: The invention relates to filter dedicated to protect eye cone cells and method associated. The eye cone cells protecting filter is intended to be applied to a transparent surface and to filter incident light for preventing eye cone cells of a user, from damages due to illumination at physiological light levels on the eye of said user, and having spectral characteristics to i) filter light wavelengths between 405 and 465 nanometers, and ii) transmit a filtered light reaching the eye cone cells and having a harmfulness on said eye cone cells under a predefined maximum threshold.

Abstract: The invention provides a method for evaluating at least one light protection level of at least one optical product intended to face an eye of a user, the method comprising the following steps: —determining at least one short-term light protection score representative of at least one short-term light protection attribute, —determining at least one long-term light protection score representative of at least one long-term light protection attribute, evaluating at least one light protection level of at least one optical product based on said at least one short-term and at least one long-term protection scores. The invention also provides an optical product comprising a frame, at least one optical system product attached to said frame and intended to face an eye of a user, a data collecting device and a controller configured to perform said evaluating method.

Abstract: The invention provides a method for determining at least one filter for a transparent support, the method comprising the following steps: —determining a quantity representative of a light sensitivity threshold of the user; —determining, for each light environment among a group of light environments, an index representative of the level of protection required by the user; —determining a score for each light environment among the group of light environments (40) and for each filter among a group of filters, said score being representative of the capacity of the filter to reach the level of protection required by the user, determining at least one filter among the group of filters based on the scores of said at least one filter in a plurality of light environments (40) among the group of light environments.
