Problems solved by technology

After the traditional white film is ready, it is used as the base film and needs to be dyed. The traditional method is the water dyeing method. First of all, for the manufacturer, the customer needs to book in advance and have a certain quantity before it can be customized, and the production There is a certain period, if the order quantity is not enough, it will basically be a loss
Moreover, the color of the lens after the water dyeing method is not exactly the same everywhere, that is, the coloring is uneven
In addition, the water dyeing method is only suitable for dyeing lenses with a diameter of less than 75mm, and the diameter of myopia sunglasses is the same as that of sunglasses. The coloring uniformity of the lenses made by the water dyeing method is even worse, and the user experience is poor.

Abstract

The invention discloses a shortsightedness sunglasses lens. The shortsightedness sunglasses lens sequentially comprises a substrate made of 400-boron-phenolic resin carbon as a main raw material, an anti-blue-light layer and a dyed and hardened layer, wherein the anti-blue-light layer comprises a first SiO2 film layer, a ZrO2 film layer, a second SiO2 film layer, a Ti2O3 film layer and an In2O3 film layer which are sequentially arranged from the substrate to the dyed and hardened layer; hardening liquid with methanal as solvent is adopted for immersion plating to form the dyed and hardened layer, solute in the hardening liquid includes 28-36 wt% of a dyeing agent, and the immersion plating of the hardening liquid is completed at the environment temperature of 9 DEG C-12 DEG C. According to the shortsightedness sunglasses lens, the substrate is sequentially plated with the first SiO2 film layer, the ZrO2 film layer, the second SiO2 film layer, the Ti2O3 film layer and the In2O3 film layer to serve as the anti-blue-light layer, human eyes are protected from being affected by blue light, and the shortsightedness sunglasses lens has good effects of preventing ultraviolet rays and preventing intense sunlight from stimulating the eyes.

Description

technical field [0001] The invention relates to the technical field of manufacturing myopia sunglasses, in particular to myopia sunglasses and a preparation method thereof. Background technique [0002] All myopia patients wear glasses to correct their eyesight. In order to achieve ideal vision correction, in addition to accurate optometry and accurate glasses, it is especially important to choose spectacle lenses with high light transmittance. However, due to strong sunlight in summer, people often need a pair of sunglasses. With the rapid development of glasses technology, resin spectacle lenses have entered the glasses consumer market due to their advantages of lightness, safety, and light transmittance close to optical glass, and there are more and more varieties, from no hardening to hardening; from low refractive index From medium refraction to high refraction; from non-discoloration to dyeing, and even to discoloration. [0003] Myopia sunglasses generally include t...
