Abstract

The invention relates to a spectacle lens capable of preventing blue light radiation and eliminating the chromatic aberration and a manufacture method thereof, which belongs to the technical field of spectacles and the manufacture method thereof. The spectacle lens is characterized in that a substrate is prepared from an organic polymer, a blue light absorbent and a UV absorbent by mixing; and a coated film layer includes a TiO2 layer, an Al2O3 layer, an ITO layer, a noble metal layer, an MgF2 layer and a SiO2 layer. The manufacture method of the spectacle lens comprises following steps of: preparing materials, mixing, stirring, curing, cleaning the substrate, reinforcing and coating film on the substrate. The spectacle lens capable of preventing blue light radiation and eliminating the chromatic aberration can effectively filter most of UV light and a portion of blue light to reduce the damage to human retina and the irritation of shortwave glare, thus reducing chromatic aberration and improving resolution of human eyes. Accordingly, persons wearing the spectacle lens can view objects clearly in weaker or stronger light environment.

Description

technical field [0001] The invention belongs to the technical field of glasses and a manufacturing method thereof, in particular to an anti-blue light radiation and achromatic lens and a manufacturing method thereof. Background technique [0002] People know that ultraviolet rays can damage the eyes, and long-term ultraviolet radiation can cause cataracts. According to research evidence, blue light with a wavelength of 400nm to 480nm is easy to damage the eyes, and blue light can penetrate the cornea and lens to reach the retina. Blue light mainly damages a pigment in the retina, which is only accumulated in retinal cells. The pigment molecules in the cells have a very strong absorption effect on the light radiation in the blue light area. As far as it is now known, this pigment is capable of promoting phototoxic reactions, absorbing optical radiation and causing damage to cells. And blue light radiation is also closely related to age-related macular degeneration. [0003]...
