Abstract: The invention relates to a method for determining a filter for an ophthalmic lens intended for being placed in front of the eye wearer, said filter being capable of improving or maintaining the visual comfort and/or the visual performance of said wearer. According to the invention, this method includes: a) a step of determining a quantity representing a dynamic sensitivity of the eye or the two eyes of the wearer to a variation in a luminous flux; and b) a step of determining at least one optical feature of said filter as a function of the determined representative quantity.

Abstract: The present invention relates to a method implemented by computer means of selecting an optical filtration of an ophthalmic device for a wearer, the method comprising: —obtaining wearer's preferences relatively to at least one predetermined type of visual environment comprising multispectral or hyper spectral data; —selecting at least one filter: —corresponding to said wearer's preferences relatively to said at least one predetermined type of visual environment, and —determined on the basis of said multispectral or hyper spectral data.

Abstract: Method for determining a refraction of at least an eye of a person under specific spectral conditions, the method including: an eye illumination step, during which the eye of the person is illuminated under the specific spectral conditions, the specific spectral conditions being provided by a polychromatic source having a spectrum which is different from the spectrum of a white light source and/or by a chromatic filter positioned before the eye of the person and illuminated by a source; and a refraction determination step during which the refraction of the eye of the person is determined under the specific spectral conditions.

Abstract: The present invention relates to optical lens for correcting color vision for individuals with color vision deficiency comprising a substrate and an absorbing dye which has at least a minimum light transmission factor at a wavelength ranging from 515 nm to 80 nm that is lower than or equal to 40% and quickly varying transmission around 500 nm and around 595 nm.
