Short Lead Time for Progressive Prescription Sunglasses - 1.59 Polycarbonate HMC Optical lenses – Boris

Production Details

Material of Polycarbonate lenses:
That is, the raw material is solid, and it is shaped into a lens after heating, so the finished lens will be deformed after being overheated, which is not suitable for high humidity and heat occasions. PC lenses are extremely tough and do not break (2cm can be used for bulletproof glass), so they are also called safety lenses. With a specific gravity of only 2 grams per cubic centimeter, it is the lightest material currently used for lenses.

Production Introduction

PC space lenses are lenses made of polycarbonate, which are essentially different from ordinary resin (CR-39) lenses! The common name of PC is bulletproof glass. Therefore, PC lenses inherit the excellent characteristics of super impact resistance of raw materials, and because of the high refractive index and light specific gravity, the weight of the lens is greatly reduced, and there are more advantages, such as: 100% anti-impact Ultraviolet rays, will not turn yellow within 3-5 years. If there is no problem in the process, the weight is 37% lighter than the ordinary resin sheet, and the impact resistance is 12 times that of the ordinary resin!

Prospect:

The chemical name of PC is polycarbonate, which is an environmentally friendly engineering plastic. Features of PC materials: light weight, high impact strength, high hardness, high refractive index, good mechanical properties, good thermoplasticity, good electrical insulation properties, and no environmental pollution. PC is widely used in CDvcddvd discs, auto parts, lighting fixtures and equipment, glass windows in the transportation industry, electronic appliances, medical care, optical communications, spectacle lens manufacturing and many other industries.

The first spectacle lenses made of PC materials were made in the United States in the early 1980s, which are characterized by safety and beauty. Safety is reflected in ultra-high shatter resistance and 100% UV blocking, beauty is reflected in the thin and translucent lenses, and comfort is reflected in the light weight of the lenses. Since the launch of the market, the manufacturers are very optimistic about the development prospects of PC lenses. They have continuously adopted new processes and new technologies in the design, manufacture and research of lenses, so that PC lenses continue to be the lightest, thinnest and hardest. , the safest direction to develop. With the rapid development of science and technology, high-tech, multi-functional and multi-purpose PC lenses are continuously introduced to meet the comprehensive needs of consumers in terms of physiology, protection and decoration. The most worth mentioning is a variety of polarized or discolored aspheric PC myopia lens products. Therefore, we have reason to believe that PC lenses will definitely become one of the leading products in the glasses industry in the future.
