ANSI Z87+ Safety (where applicable)

Our safety frame line (Heat Wave Z87, Wiley X, Smith Elite, Spy ANSI, Oakley Standard Issue, Wye/Delta) meets or exceeds ANSI Z87.1-2020 impact and optical requirements, marked Z87+ on frame and lens. Ray-Ban Meta, Oakley Meta, and other consumer-grade frames are not Z87-rated — check the product specs for each model.

Specs & Fit

Impact-rated polycarbonate lenses with 100% UVA/UVB protection across the safety line. Look for the Z87+ mark on the frame and lens to confirm the ANSI rating. Anti-fog, polarized, and mirror options vary by model. Fit runs unisex, medium to large.
