FAQ
All our sunglasses offer UV400 protection, blocking 100% of UVA and UVB rays. They also comply with current European standards for sunglasses.
Lens categories indicate how much visible light the lenses filter. The higher the category, the less light they let through.
Category 1: light-tinted lenses for low-light conditions.
Category 2: medium-tinted lenses for moderate sunlight.
Category 3: darker lenses for bright, sunny conditions.
Most of our sunglasses feature Category 3 lenses, while some styles with lighter lenses may be Category 1 or 2.
