Which lens material is known for being especially impact resistant?

Polycarbonate is renowned for its exceptional impact resistance, making it a preferred choice for eyewear, especially in situations where safety and durability are paramount. This material is highly effective in preventing shattering upon impact, which is particularly important for protective eyewear and children's glasses.

In addition to impact resistance, polycarbonate lenses are also lightweight, offering comfort for prolonged wear. They also feature inherent UV protection, adding another layer of benefit for users concerned about sun exposure.

While Trivex also has strong impact resistance and is lightweight, polycarbonate typically edges out in applications requiring maximum safety due to its broader track record in rigorous environments. Plastic lenses, while lightweight and affordable, generally do not provide the same level of impact resistance as polycarbonate. Glass lenses, on the other hand, although known for superior optical clarity, can shatter upon impact, presenting a safety issue that polycarbonate effectively addresses.
