PC lenses are a material that is more impact-resistant than resin lenses. Generally, resin lenses are thermosetting materials, that is, the raw materials are liquid and heated to solid lenses. PC lenses is also called "space lenses". Its chemical name is polycarbonate, which is a thermoplastic material. That is, the raw material is in a solid state and is shaped into a lens after being heated. PC lenses are extremely tough and do not break (2cm can be used for bulletproof glass), so they are also called safety lenses. They are often used in transparent glass for aviation equipment, police masks and astronaut helmet masks. It is very light, only about one-tenth of glass, and only half the weight of traditional resin lenses. It can be said to be the lightest material currently used for lenses.
1. What is PC lens?
1. Definition: PC lenses are spectacle lenses made of polycarbonate, which have the characteristics of high hardness, light weight, and impact resistance.
2. Characteristics: Compared with traditional glass or plastic lenses, PC lenses are more durable, lighter and safer. They are a very popular eyeglass lens material.
Therefore, the lenses made of this material is especially suitable for sportsmen and active children. Besides, this kind of material pays special attention to the defense function of ultraviolet when developing and improving. It is the kind of lenses material with the best UC resistance function. The lenses degradable and relatively environmentally friendly products.
In European and American countries, PC lenses have become the safest lenses required by primary and secondary school students, suitable for people who wear frameless frames with low-grade numbers.
