AN OPHTHALMIC LENS FOR IMPROVING NIGHT DRIVING VISION AND A METHOD FOR OBTAINING THE SAME

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: formula (I), where sum is a discrete or continuous sum operator, Lambda is the wavelength in nm, lens T% is the transmittance of said 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%. 此眼科镜片具有前面和后面，并且具有：对于范围为380nm至500nm的波长至少20％的光截止因数CutLED，CutLED如下定义：公式(I)，其中Σ是离散或连续求和算子，λ是以nm为单位的所述波长，镜片T％是所述镜片的透射率％并且LED发射％是白色发光二极管的光谱分布％；以及在所述前面和所述后面上的减反射涂层，所述减反射涂层在可见光区域中针对暗视觉的光反射率Rv'小于或等于1.5％。
