Production method of UV 420 mixed-injected filtering protective lens

Abstract

The invention discloses a production method of UV 420 mixed-injected filtering protective lenses. The method which mainly comprises the steps that dried plastic rice, UV 420 toner, blue light toner, 8315 toner, 8150 toner, 5602 toner and VI3R toner are fully mixed according to a certain proportion to obtain mixed materials; the mixed materials are put into a stirrer, uniformly stirring is carriedout, and then drying is carried out; and the evenly stirred and dried mixed materials are injected into an injection mold, and injection molding is carried out to form a semi-finished lens product. Byadopting the production process of the production method to produce the lens, the semi-finished lens product can be formed in one step by using the injection mold, and then only the semi-finished lens product needs to be dyed and strengthened. The production process avoids the defects of adhesiveness, hardness, film cracking or film peeling and the like existed on a film coating layer or a coating layer in the traditional process, so that the yield of produced lens finished products is extremely high.

Description

technical field [0001] The invention relates to the technical field of lens manufacturing, in particular to a production method of a UV420 mixed injection filtering protective lens. Background technique [0002] With the increase in the frequency of mobile phone use, more and more people wear glasses to protect their eyes through the use of mobile phones for a long time. Therefore, the quality of the glasses has also attracted much attention. [0003] Among them, the lens is an important part of the glasses, and the resin lens is the most common lens at present. The resin lens is an organic material with excellent optical properties, impact resistance, non-fragility and light weight. [0004] In the existing production process of resin lenses, the substrate plastic rice of the resin lens is usually formed into a lens substrate first, and then a coating layer or a coating layer is added to the lens substrate through coating technology or coating technology, and the coating la...

Problems solved by technology

However, during the production process, it was found that the defective rate of resin lenses produced by this production process is extremely high, and the coating layer or coating layer has defects such as adhesion, hardness, cracking or stripping.

[0005] In view of this, the present inventor aimed at the many shortcomings and inconveniences caused by the imperfect design of the above-mentioned method of producing resin lenses, and deeply conceived, and actively researched and improved the trial production to develop and design the present invention.
