II. Features:
1) Semi Finished Lenses:
Semi-finished lens is the raw blank used to produce the most individualized RX lens according to thepatient's prescription. Different prescription powers request for different semi-finished lens types or base curves.
2) PC Lenses:
Impact Resistant: Polycarbonate material was originally made for uses on canopies covering fighter planes and then made its way into space on astronaut visors and space shuttle windshields. Today it is readily available to the public. It impact resistance makes the material extremely suitable for sports, industrial safety goggles, and children's eyewear.
Scratching: The reason for polycarbonate lenses' impact resistance is because of its "softness". Softer materials will flex instead of fragment when met with great force. However, the property allows lenses to be scratched easily. Therefore, every single one of our polycarbonate lenses is multi-coated with hard coating that forms a protective layer around the lenses allowing the lenses to be free from scratches while retaining its impact resistant qualities.
UV Protection: Polycarbonate lenses inherently carries UV protection properties that blocks nearly 100% of the UV rays from entering the back of the retina.
3) Who need the PC lenses:
 | Lighter and thinner than traditional plastic lenses makes Polycarbonate lenses great choice for people with active lifestyles who desire comfort, protection, and performance with a thinner and lighter lens. The High index 1.59 Polycarbonate lens is not only thin and light weight but also very impact resistant making it essential for children’s eyewear and for use as safety lenses. |
III. Coating Choice:
| Hard Coating | AR Coating/ Hard Multi Coated | Super Hydrophobic Coating/ Crazil Coating |  |
| Enhancing the hardness and resistance on the surface of lenses, prevent lenses from being scraped easily . | Coating anti- reflective film can effectly reduce the reflection of light , make the lenses more cclear and transparent . | Making the lens waterproof, antistatic,anti slip and oil resistance,also convenient for clean
