Which material is commonly used for safety glasses due to its impact resistance?

Polycarbonate is commonly chosen for safety glasses because of its exceptional impact resistance. This material is lightweight, making it comfortable to wear for extended periods while offering significant protection against flying debris and impact from various objects. Polycarbonate is also less likely to shatter compared to glass, which further enhances safety.

In high-risk environments, such as construction sites or laboratories where chemical splashes or physical hazards are present, using polycarbonate eyewear provides durability and reliable protection that meets safety standards. The material can withstand extreme conditions without compromising visibility, making it a preferred choice for both industrial applications and personal protective equipment.

Although other materials like glass, acrylic, and styrene have their own benefits, they do not match polycarbonate in terms of impact resistance. Glass, while scratch-resistant and optically clear, can shatter upon impact, posing a risk to the wearer. Acrylic is lighter than glass but is more prone to scratching and offers lower impact resistance. Styrene is not typically used for safety glasses due to its lower toughness compared to polycarbonate.
