In the international optical lens field, the mature technology of optical lenses is a single-substrate coating process, that is, using glass, crystal, PC or resin and other materials to make a lens substrate through optical technology, and then coating the surface such as anti-wear through the coating process , Anti-fouling, anti-ultraviolet, anti-radiation, anti-blue light, anti-glare and other functions.

The single-substrate coating process is relatively simple and the manufacturing cost is relatively low, which is widely used in optical companies at home and abroad. After Sharpeye introduced the technology from Switzerland in 2005, it was at the stage of rapid development of the global Internet. Domestic computer users ranked first in the world. Sharpeye now realized that the era of anti-computer radiation lenses had arrived, and it also knew The anti-radiation effect of the substrate coated lens was minimal, and at that time, it was still in the stage of commercial concept.

Sharp Eye executives quickly reached an unanimous decision and decided to set up an optical research and development center in Hong Kong to independently develop more effective radiation-proof optical lenses.

Dozens of optical experts, precision technology experts, and engineers carry out scientific research experiments day after day, ushering in the birth of synthetic optical technology. Synthetic optical technology turns a single substrate into a multi-substrate, and through the precise synthesis of multilayer substrates, the biggest advantage of this technology is that the radiation protection efficiency is greatly improved. Single-coated lenses are coated with a thin layer of anti-radiation film on the surface of the lens, which has a low filtering rate of blue-ray radiation on the computer screen. In addition, the surface coating is not wear-resistant, because the lens will be frequently wiped, and the coating will be coated after a period of time. disappear slowly.

The multi-substrate precision synthetic lens completely subverts the single-substrate coated lens, synthesizing the radiation protection material between the multi-layer substrates, not only filtering the blue light radiation rate of the computer screen several times, but also the lens surface wiping has no effect on radiation protection influences. This technology has strong design redundancy, that is, the substrate synthesis layer can be designed completely according to actual needs. According to repeated experiments of the R&D center, 18-layer synthesis achieves the best effect of filtering blue light radiation, and has been awarded a national patent as the optical standard of synthetic lenses .

The multi-substrate synthetic lenses independently developed by Sharp Eye also have better performance than single-substrate optical lenses in terms of light transmittance, UV protection, anti-glare, and retinal imaging. Since the market, they have been favored by the majority of computer users.
