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: This ophthalmic lens for improving vision has a light cut factor CutLED between 32% and 90%, for wavelengths ranging from 380 nm to 500 nm, defined by formula (I), where Σ is a discrete or continuous sum operator, λ is the wavelength in nm, lens T % is the spectral transmittance of the lens in % and LED emission is the spectral distribution of a white light emitting diode; a mean luminous transmittance in the visible range higher than or equal to 75%; and light transmitted through the ophthalmic lens has a colorimetric value b*, as defined in the colorimetric CIE L*a*b* with illuminant D65, lower than 25.
