ANSI Z78.1 is a consensus standard that outlines performance, testing, and labeling criteria for solar and protective eyewear. It specifies optical quality, UV filtration, visible light transmission, and impact resistance requirements to ensure consistent consumer protection in outdoor use. The standard also addresses frame durability, lens geometry, and marking conventions so products can be evaluated and compared. Test methods include mechanical impact and environmental exposure assessments, supporting regulatory compliance and informed purchasing decisions for safety-focused buyers.
