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 ? is a discrete or continuous sum operator, ? 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.

Abstract: This ophthalmic lens has a front face and a rear face, and has: a light cut factor CutLED of at least 20% for wavelengths ranging from 380 nm to 500 nm, CutLED being defined by: CutLED = 100 - ? ? = 380 500 ? ( lens ? ? T ? % × LED ? ? emission ? ? % ) ? ? = 380 500 ? LED ? ? emission ? ? % where ? is a discrete or continuous sum operator, ? is the wavelength in nm, lens T % is the transmittance of the lens in % and LED emission % is the spectral distribution of a white light emitting diode in %; and an antireflective coating on the front and rear faces having a luminous reflectance in the visible region for scotopic vision Rv? lower than or equal to 1.5%.
