Ophthalmic Lens for Improving Vision

Ophthalmic Lens for Improving Vision

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...

Zusammenfassung: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.
