Some Sunglasses models are ANSI Z87.1+ certified. This ensures high-impact protection, mandated for hazards involving high-velocity projectiles and heavy objects. The "+" symbol confirms compliance with rigorous tests: high-velocity impacts from a 1/4-inch steel ball at 150 fps, high-mass impacts from a 500-gram dropped projectile, and penetration resistance.

Some Sunglasses models are UV400 rated and polarized. These lenses provide comprehensive eye protection by blocking 100% of harmful UVA/UVB rays (up to 400nm400 nm400nm) and filtering out intense glare from surfaces like water, snow, and roads. While UV400 focuses on health protection, polarization enhances visual clarity and comfort, making them ideal for driving, fishing, and outdoor activities.

Some Sunglasses models come certified with MIL-PRF-31013, which is a rigorous U.S. military ballistic protection standard for spectacles, requiring lenses to withstand a .15 caliber projectile at 640-660 feet per second. This standard ensures high-velocity impact resistance for combat, significantly exceeding civilian ANSI Z87.1 standards, while also covering UV protection, chemical resistance, and optical quality.
