The "Category - CAT" number indicates the level of light transmission in the visible range. How clearly and extensively you can perceive your surroundings largely depends on the lens you choose.
Lens BLADE
Replacement Lens BLADE Video Overview
The BLADE offers maximum flexibility with interchangeable lenses for a wide range of light and weather conditions. The innovative lens system allows you to quickly and easily swap lenses, so you can adapt your sports sunglasses to changing conditions.
The polarised black lens (CAT. 4) is made from TAC material and provides effective protection against UVA and UVB rays. Lenses from CAT. 0 to CAT. 3 are made from durable polycarbonate and offer UV380 to UV400 protection, depending on the category. The Nano-HD coating enhances contrast in varying light conditions while providing a water-repellent finish.
With lens categories ranging from CAT. 0 to CAT. 4, you can choose the right BLADE lens for cycling, running, ski touring and other outdoor activities.
