"Impacto" is an extremely impact-resistant lens developed exclusively by Carl Zeiss Vision Sunlens, which is more than five times stronger than ordinary polycarbonate material.
While providing eye protection against ballistic impact threats in accordance with global military standards, it also blocks nearly 100% of harmful UV rays.

Prism offset lens technology reduces distortion and misalignment (prism effect) in the central and peripheral areas of the field of view, ensuring a wide, clear field of view similar to that of the naked eye. This lens was developed by Carl Zeiss Vision Sunlens, which has reviewed the decentered lens that reduces the general prism effect from an optical and manufacturing technology perspective, and further improved its functions. This creates a wide, comfortable field of view similar to that of the naked eye, giving riders safety and peace of mind.
Generally, when using high-curve lenses such as sports sunglasses, the angle of curvature of the frame and the line of sight do not match the optical axis, resulting in prescription errors and image misalignment (prism), and incompatibility of optical characteristics. Prism narrows the field of view and can also cause eye fatigue. When decentered lens technology is used, image misalignment can be eliminated when the line of sight is from the center of the lens, but image misalignment and prism phenomenon cannot be eliminated when the line of sight is from the peripheral part of the lens. Prism offset lenses have a unique prism correction program calculated over a wide range of the field of view and a special design calculated in detail in the front area of the lens, which reduces the prism effect that causes image misalignment, ensuring accuracy within a range of 50 mm from the center of the lens and enabling a 20% field of view expansion, ensuring a field of view close to that of the naked eye and providing a comfortable field of view.
The frame is made of "TR-90LX" material, which has excellent impact resistance and chemical resistance. It is a proven material that is gentle on the skin and can be used safely because it has excellent resistance to bending fatigue and does not use plasticizers. The nose pads and temple modern parts can be freely deformed, allowing fine adjustments such as width and height adjustment to suit the rider or runner's movements and the shape of the face. The rubber parts that come into direct contact with the skin are made of "Labalon MJ Series". It is a highly safe material that has passed the Food Sanitation Act, and is gentle on the skin and provides an excellent fit.
