Large fit but not oversized.Lens: Prizm RoseVLT: 26% (CAT 2)Size: LargeLens Shape: CylindricalLensPrizm Rose is best suited for snowy and cloudy days with the rose tint increasing depth perception and contrast. Prizm technology blocks specific wavelengths of light whilst 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.Visual Light Transmission, VLT, refers to the amount of light that penetrates a lens. A low percentage means less light passes through and a higher percentage lets an increased amount of light through. A lens with a lower VLT rating is better for bright conditions, where as one with a higher VLT is more suited for overcast and snowy days.
