Highly anti-reflective blue light blocking lens

Abstract

The utility model discloses a kind of high antireflection blue light prevention lens, including resin substrate, resin substrate surface is equipped with hard layer, silane coupling agent layer, blue light prevention film group, wide spectrum antireflection film group in sequence, wide spectrum antireflection film group surface can also be provided with wear layer. Among them, the thickness of silane coupling agent layer is 5-10nm;Blue light prevention film group is composed of 2-3 pairs of high, low refractive index film layer alternately stacked;Wide spectrum antireflection film group is 3-5 layers of tantalum pentoxide film layer and 3-5 layers of silicon dioxide film layer alternately stacked, and both have regular hexagon honeycomb structure. The utility model cooperates through each film layer, has excellent blue light prevention performance and high transmittance simultaneously, with good mechanical property and film layer combination firmness simultaneously, can effectively protect human eye, improve visual experience, applicable to various optical equipment.
