Although the spectacle lenses using glass materials are not performing as well as they did before in terms of market shares, that cannot change the fact that glass is the best material for ophthalmology. Currently, the industrial mode of large-scale industrialization has suppressed people’s correct awareness and demand for ophthalmological materials.
We use the quality glass of Schott, PPG and Japan and the quality optical glass customized in China. We have such glasses of general type, classical type, reinforced platinum and rare earth. For the specially customized products of optical glass, the existence of refined production processes and the addition of rare earth elements into the glass enable the colors and contrast of the lenses to receive the best perception, protect them against daily UV and provide them with an excellent performance, including multi-layer glare-proof, ultrathinness, hardening, oleophobic and hydrophobic property, the ability to prevent and clean fingerprints. These lenses are used by customers for replacement of sunglass lenses, but excel over the original lenses in terms of optical performance. Our customers use them more in developing the new products of high-end sunglasses. These outstanding lenses have added a better optical performance to these products. Who makes the best sunglass lenses？We are one of the makers undoubtedly.
In particular, we apply the technology from the optical filter system of world-famous brands to the lenses of high-end sunglasses and functional spectacles that prevent blue light. This is the lens of optical glass for a new camera that is rarely seen in the market now. Compared with the lenses of traditional glass, Sunphye glass lens:
○ is ultrathin, with a thickness of 0.8mm-1.0mm;
○ is manufactured with a unique toughening process of high strength and remained intact in a test conducted with a steel ball of 64g dropped from a height of 1.27m and in a pressure test of as high as 980N;
○ has a stable excellent quality, including exquisite shaping, a high precision of processing and smooth chamfer;
○ provided clear imaging in a HD test where the lenses of nylon, CR39 and PC showed blurred imaging;
○ had basically no color deviation in a color temperature test where most lenses of resin had color deviation;
○ remained smooth and scratchless in a knife scratch test where all the lenses of resin for comparison had obvious scratches;
○ has higher density performance and a lens film of better optical performance under a high-temperature coating process where the lenses of resin cannot bear;
○ uses double-sided coating, which outperform most products of one-sided coating in the market in ensuring the consistency of the optical performance indicators of both sides, reducing glare, preventing water, oil and scrape, protecting eyes, making it easier to clean the lenses and extending the service life of the products.
