Abstract

The invention discloses an anti blue-ray eye-protective lens and a preparation method thereof. The preparation method for the anti blue-ray eye-protective lens comprises the following steps: (1) mixing nano-oxide and a coupling agent to prepare a modified oxide; (2) adding the modified oxide which is prepared in the step (1) and transition metal oxide core-shell type nano-particles into polymer monomers, then adding an ultraviolet absorbing agent, mixing uniformly, and adding an initiator to perform a polymerization reaction to obtain a pre-polymer mixture; (3) performing primary curing; (4) performing secondary curing to obtain the anti-blue ray eye-protective lens. According to the anti blue-ray eye-protective lens and the preparation method thereof, the best process conditions of the anti-blue ray eye-protective lens are investigated; organic dyes, such as black pigment and yellow pigment, are not added; blue ray reducing effects of various raw materials in a lens preparation process are screened layer by layer; the using amount of the modified nano-oxide is reduced by adding the coupling agent; the effects of reducing blue ray damage and increasing light transmittance are achieved; the eye fatigue can be effectively alleviated; the chromatic aberration is reduced; the damage to human eyes caused by blue ray and electromagnetic irradiation is reduced.

Description

technical field [0001] The invention relates to the field of lens technology, in particular to an anti-blue light goggle lens and a preparation method thereof. Background technique [0002] Blue light is an important part of visible light. There is no separate white light in nature itself. When blue light is mixed with green light and yellow light, it presents white light. Green light and yellow light have less energy and are less irritating to the eyes. Blue light has a short wavelength and high energy, and can directly penetrate the crystal and reach the retina of the fundus. [0003] Artificial light sources such as LEDs and computer background lights retain a large amount of blue light, which makes the artificial light whiter and brighter. Some particularly white and bright lights give people a feeling of bluishness, which is caused by an excessively high proportion of blue light. All kinds of visible light emitted by various new artificial light sources such as compute...
