Resin lens is a kind of optical lens made of resin as raw material, which is processed, synthesized and polished by precise chemical process. At the same time, resin can be divided into natural resin and synthetic resin.

The advantages of resin lenses: strong impact resistance, not easy to break, good light transmission, high refractive index, light weight and low cost.

PC lens is a kind of lens formed by heating polycarbonate (thermoplastic material). This material is developed from space exploration, so it is also called space film or space film. Since PC resin is a thermoplastic material with excellent properties, it is especially suitable for making spectacle lenses.

Advantages of PC lenses: 100% ultraviolet rays, no yellowing within 3-5 years, super impact resistance, high refractive index, light specific gravity (37% lighter than ordinary resin sheets, and impact resistance is as high as ordinary resin sheets) 12 times the resin!)
