II. PC Features:
Polycarbonate was developed in the 1970s for aerospace applications, and is currently used for the helmet visors of astronauts and for space shuttle windshields. Eyeglass lenses made of polycarbonate were introduced in the early 1980s in response to a demand for lightweight, impact-resistant lenses.
Since then, polycarbonate lenses have become the standard for safety glasses, sports goggles and children's eyewear. Because they are less likely to fracture than regular plastic lenses, polycarbonate lenses also are a good choice for rimless eyewear designs where the lenses are attached to the frame components with drill mountings.

III. Polycarbonate Lens VS Standrad Plastic Lens
Polycarbonate prescription lenses are one of the most common choice for eyeglasses for several reasons.
| ---Polycarbonate lenses are thinner than regular plastic lenses, and they offer the best eye protection capability because it is virtually shatterproof.
---Polycarbonate lenses are a good all around choice, even though plastic lenses have better visual acuity.
---Polycarbonate lenses have higher impact and scratch resistance than standard plastic lenses(including other high-index lenses) because these lightweight lens materials are relatively "soft" — which means they can absorb energy without lens fracturing. | |
