Manufacturing of flash sunglasses
Mirror sunglasses mean those that have a mirror coating or flash coating applied to the outside of lenses so that they look like small mirrors. The color of the mirror has nothing to do with the hues of the lenses. Multiple alternate layers of a particular thickness are made of dielectric substances (or metal sometimes). The color of the flash film on the lenses of sunglasses is the color as a result of light reflection. Such reflection does not need a high effect of ray reflection. Instead, it is only intended to cause the reflected light of sunglass lenses to become the dazzling color that should appear through the interference effect of the light of the dielectric film and is extremely decorative.
Secret behind flash sunglasses
We process tens of thousands of flash mirrors for lenses. From the perspective of the requirements of optical technology, the reflected colors of lens surface is required to have nearly consistent paraters. Only in this way is it possible to ensure the consistent surface color of any two lenses when they are combined to form a pair of spectacles. This requirement is relatively hard to meet for coating technology. As is known to all, complete consistency is hard to achieve for the products of the same model between different equipment. This is a challenge confronting our company of excellent technology and even the world-famous brands. The current approach is to scrap rejects having parameters that exceed the range through the color limit standard. Full considerations need to be given to the flash lens products of high standard from the aspects of equipment configuration, design of film system, training of operators and the monitoring method of film system. Strict control over production processes enables manufactured products to have highly stable colors and a high rate of accepted products. Some sunglass companies consider things only from commercial perspective and permit rejects to access the market by leveraging the weakness that human eyes cannot make precise identification so as to lower production cost and reach the purpose of making high profits. The difference in the quality advantages of Sunphey is so subtle as to be undiscernible to naked eyes and can be identified more accurately only with instruments. It is such difference in the advantages that enables the customers who have used our products for long to receive many invisible advantages.
The flash lenses produced by Sunphey include Blue F lash, Green F lash, Copper Flash, Orange Flash, Yellow-Green Flash, Red Flash, Silvery Flash, Gold Flash, Purple Flash and Champagne Flash. We can manufacture Teardrop-shape glass lenses of three different dimensions: Classics, Enhancement Classics and Polarized Classics and provide customized new shapes for many customers that develop new products.
