II. Features:
1) Semi Finished lenses:
 | The semi-finished lenses are produced in a casting process. Here, liquid monomers are first poured into moulds. Various substances are added to the monomers, e.g. initiators and UV absorbers. The initiator triggers a chemical reaction that leads to hardening or "curing" of the lens, while the UV absorber increases the UV absorption of the lenses and prevents yellowing. |
2) Polycarbonate:
With the replacement of the lens Nowadays, the glass lens has gradually been replaced by the light and abrasion resistant optical resin lens. However, the technology is continuously improving. Now the PC lens with better quality has been developed and applied successfully to the optical industry. PC lens, also known as "space film", because of its excellent impact resistance, it also has a commonly known as bullet-proof glass.
3) The advantages of the PC lenses:
- Excellent impact-resistance - 10 times more impact resistant than other lenses.
- Thin - About 20 to 25 percent thinner than plastic or glass lenses.
- Lightweight - About 20 percent lighter than plastic lenses.
- Blocks 100 percent UV rays without needing a special coating.
