摘要： A computed factor allows quantifying the efficiency of a light filter to stimulate a non-visual physiological effect which is responsive to light entering into a subject's eye. The efficiency factor is based on a spectral light transmittance of the filter over the wavelength visible range, on a spectral sensitivity profile of the non-visual physiological effect, and on a spectral distribution of the light which enters into the subject's eye without using the filter. Such efficiency factor is useful in particular for an ophthalmic element designed for stimulating a non-visual physiological effect which is based on melanopsin light-absorption.

摘要： 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.
