The eVZero Blades is a high-performance sports glass that takes its inspiration from streetwear culture. The single-piece shield has been fitted onto a rimless frame resulting in a wide field of view with minimum weight. Unobtainium nosepads and temples keep the glasses securely in place, and Prizm lens technology ensures you see in greater detail with crisp and enhanced clarity.Lens: This lens is suitable for medium light conditions with a tint that increases contrast while reducing glare, making it easier to see changes in the terrain ahead. Well suited for trail cycling and running. The base lens tint is rose. Prizm technology blocks specific wavelengths of light while boosting others to provide maximum contrast and enhanced visibility. This greater clarity results in reduced reaction times and increased performance over a wide range of light conditions.VLT: 35% (CAT 2) - Visual Light Transmission, VLT, refers to the amount of light that penetrates a lens.
