what are polycarbonate lenses

Polycarbonate lenses are a type of eyeglass lens made of a strong yet lightweight plastic that is shatterproof and impact-resistant. They are designed to withstand impact, correct vision issues, and give glasses a streamlined appearance. Polycarbonate lenses are both transparent and sturdy, making them suitable for use in both standard prescription glasses and safety glasses or goggles. They are also the lens of choice for highly active people and kids, and are often found in children’s glasses and sports eyewear. Polycarbonate lenses are up to 30% thinner than standard plastic or glass lenses, and can accommodate strong prescriptions without adding too much bulk. They are also customizable, with various coatings and treatments available, including anti-reflective coatings and blue-light-filtering coatings. Polycarbonate lenses are naturally UV protective, blocking 100% of UV rays without requiring an additional coating or treatment. They are also available as progressive lenses, which feature multiple zones of vision correction. However, polycarbonate lenses are susceptible to scratches and require scratch-resistant coating for durability. They are also more expensive than other commonly prescribed lens types.
