Which materials commonly provide impact resistance and UV protection in protective eyewear?

• A. Glass with UV coating
• B. CR-39 with no UV
• C. Acrylic with no impact protection
• D. Polycarbonate and Trivex offer impact resistance and UV protection

Answer: (D)

When choosing protective eyewear, you want a material that can withstand impact and also block UV light. Polycarbonate and Trivex fit that need because they are inherently impact resistant and provide built-in UV protection. This means they shield the eye from high-velocity particles and from ultraviolet rays without relying on separate coatings. Other options either compromise on impact resistance (glass and acrylic without proper protection) or rely on coatings for UV protection that may wear off or aren’t as protective by themselves (CR-39 without UV). So, the combination of strong impact resistance and built-in UV filtering is most reliably provided by polycarbonate and Trivex.
