High-indexplastic or glass lenses bend light more effectively than lenses made of plastic or polycarbonate material. The result is thinner and lighter eyewear that is comfortable to wear. High-index lenses are great for people with strong prescriptions. However, they are more costly than plastic o...
Polycarbonate Lenses Thickness: Polycarbonate has a higher index of refraction than Trivex (1.58 vs. 1.53), so polycarbonate lenses are about 10 percent thinner than Trivex lenses ---Weight: Polycarbonate lenses are lighter than glass lens, so polycarbonate i...
On the other hand, polycarbonate is known for its exceptional strength and is used in demanding applications such as bulletproof windows and eyewear lenses, due to its high impact resistance and optical clarity. 15 Vinyl products are generally less expensive and easier to manufacture, making them ...

Polycarbonate's structure, characterized by carbonate groups within its chains, provides it with high impact resistance and the ability to transmit light almost as well as glass, which is why it's often used in bulletproof windows and eyewear lenses. 6 Copolymers can exhibit properties not found ...
Polycarbonate vs. PVC: Applications and Uses The main applications for polycarbonate (extruded sheet and molded parts) are listed below: Medical equipment: Cameras, lenses, medical tools. Eye protection: Safety glasses and face shields. Optical lenses: Spectacle lenses, instrument lenses, fiber optic...
Add to this the advantage that polycarbonate is just one-third the weight of acrylic or one-sixth as heavy as glass and the only drawback is that it is more expensive than either acrylic or glass. Polycarbonate is also used in the electronics industry. Apple's original iMac featured ...
Plastic polycarbonate sheets are found in products like bullet-proof glass, car headlamp lenses, glazing and roofing. A polycarbonate plastic sheet offers excellent machinability. Designers and manufacturers prize polycarbonate sheets for their toughness, stiffness and excellent dimensional stability. When ...
