Eye protection is a baseline requirement, defined by UV radiation absorbance and certified impact resistance—key points for any factory audit checklist.
- UV Protection (UV400 Standard): “UV400” certifies that the lens blocks 100% of all ultraviolet light up to 400 nanometers. For performance eyewear, this is a prerequisite. With superior materials like Polycarbonate and Trivex, this protection is inherent to the polymer itself, not a coating that can wear off. This guarantees permanent protection and is a key specification for any bulk order sports eyewear.
- Impact Resistance (ANSI Z87.1+): This American National Standard is the benchmark for safety. The “+” designation is critical, certifying the eyewear has passed high-velocity impact tests. Sourcing ANSI Z87.1+ certified eyewear is the only way to responsibly protect riders and is a primary question for any potential sport sunglasses OEM partner.
The choice of lens material is therefore the first and most criti
