Horn eyeglass frames and polycarbonate lenses serve different roles in UV protection. While horn offers no inherent UV-blocking properties, polycarbonate lenses provide 100% defense against harmful rays. For optimal eye safety, combine horn frames with polycarbonate or UV-coated lenses. Polycarbonate remains superior for impact resistance and built-in protection, making it ideal for active users, whereas horn suits those prioritizing aesthetics and hypoallergenic materials.
