Abstract

The invention discloses an anti-blue light goggles lens and a preparation method thereof. The preparation method of the anti-blue light goggles lens comprises the following steps: (1) preparing a modified oxide by mixing a nanometer oxide with a coupling agent; (2) ) adding the modified oxide and transition metal oxide core-shell nanoparticles prepared in step (1) to the macromolecular monomer, then adding an ultraviolet absorber and mixing evenly, and then adding an initiator to carry out a polymerization reaction to obtain a prepolymerized mixture ; (3) primary curing; (4) secondary curing, that is. The present invention investigates the optimal process conditions of the anti-blue light goggles, does not add organic dyes such as melanin and yellow pigment, and screens the blue light reduction effect of each raw material in the lens preparation process layer by layer. Adding a coupling agent reduces the The amount of modified nano-oxide can reduce blue light damage and increase light transmittance, which can effectively reduce eye fatigue, reduce chromatic aberration, and reduce damage to human eyes due to blue light and electromagnetic radiation.

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...
