Are The Lens King Lenses Impact Resistant?

Yes. Our lenses meet the robustness requirements of EN ISO 12312-1 and are CE-marked under Regulation (EU) 2016/425. They are verified with the drop-ball impact test — a steel ball dropped onto the lens, which it withstands without breaking — the same method behind ANSI Z80.3 and the FDA standard (21 CFR 801.410) for the US market. Impact-resistant lenses are not unbreakable or shatterproof, and they are general-purpose sunwear, not industrial safety eyewear (ANSI Z87.1 / EN 166).
