preparation example Construction

[0041] The preparation method of down conversion light conversion agent 1 comprises the following steps:

[0042] (1) Use (CH3COO)2Zn, MnO, SrCO3, SiO2 and Eu2O3 as raw materials, and weigh each raw material according to the stoichiometric ratio of the chemical formula Sr4-xMnZnSi2O9:xEu2+, where the value range of x is 0.05≤x≤0.15; Adding 0.05-3% NH4F and 0.5-2% H3BO3 as flux;

[0043] (2) Fully grind the raw materials obtained in step (1) for 30 minutes, and mix them evenly;

[0044] (3) Put the mixture obtained in step (2) into a corundum crucible, and then place the corundum crucible and the mixture in a tube furnace for burning. The burning temperature is about 1350°C, and the heating rate is 5°C / min. The time is 4 hours, and the sintering atmosphere is a mixture of 5% hydrogen and 95% nitrogen; after the burning is completed, the sample is cooled to room temperature with the furnace, and the sintered body is obtained by taking it out;

[0045] (4) Add distilled water t...

Abstract

The invention discloses an anti-blue light glasses substrate and a pair of anti-blue light fatigue-resistant glasses. The anti-blue light glasses substrate is prepared from a substrate main body material as well as a down-conversion light conversion agent 1, a down-conversion light conversion agent 2, ferric oxide, zinc oxide, aluminum oxide, silicon oxide, magnesium fluoride nanoparticles, an ultraviolet absorbent and a surfactant which are dispersed in the substrate main body material. The pair of anti-blue light fatigue-resistant glasses comprises lenses composed of a glass holder and the lens composed of the anti-blue light glasses substrate and anti-reflection films arranged on the convex surface and the concave surface, and an attapulgite photocatalyst coating is arranged on the surface of the glasses frame of the glasses holder. The pair of anti-blue light fatigue-resistant glasses provided by the invention can block harmful blue light, and simultaneously, beneficial blue lightcan penetrate through the anti-blue light fatigue-resistant glasses, thereby effectively reducing the injury caused by the blue light, reducing chromatic aberration and improving the light transmittance of the glasses; and the anti-blue light fatigue-resistant glasses can release negative oxygen ions under any conditions, thereby relieving eye fatigue.

Description

technical field [0001] The invention belongs to the technical field of glasses, and in particular relates to a base sheet of anti-blue light glasses and anti-blue light anti-fatigue glasses. Background technique [0002] Blue light is the light closest to ultraviolet light and has the highest energy. Its wavelength is between 380 and 500 nm, and it appears blue in the perception of human eyes. Studies have shown that blue light not only exists in sunlight, but also exists in large quantities in computer monitors, fluorescent lamps, mobile phones, digital products, LED displays, Yuba, projectors, laser pointers, flashlights, etc. [0003] Blue light is more harmful to the human body than other wavelengths of light, but not all blue light is harmful. The short-wave blue light of 380-465nm has extremely high energy, which can penetrate the lens and reach the retina, causing myopia and photodamage to the retina. In severe cases, it can lead to visual impairment, macular degener...
