Born in the 80’s, the Frogskins was Oakley’s first-ever lifestyle sunglass and quickly gained a cult following. This modern version uses the same classic shape but with up-to-date technologies and the latest materials. The O Matter frame is lightweight and durable, while Oakley’s market-leading Prizm lens technology ensures you see in greater detail with crisp and enhanced clarity.Lens: This lens is suitable for bright light conditions with a tint that increases contrast. The base lens tint is grey. 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: 12% (CAT 3) - Visual Light Transmission, VLT, refers to the amount of light that penetrates a lens.
