• Amber or yellow colors are intended for use in flat to hazy light conditions and offer high contrast necessary in high-speed, high altitude sports such as skiing by filtering out blue light which makes focusing difficult.
• Vermilion (pink) actually helps to absorb light in foggy or gray conditions increasing contrast and depth perception, a must for high-speed sports in the winter.
• Brown lenses offer the true-color perception characteristics of a gray or smoke lens, but also retains some of the blue-light removing / contrast increasing characteristics of a light amber lens.
• Clear...why? Because if you're skiing at night, it's the only lens color that will allow their eyes to see anything at all.
• Gray or smoke colored lenses are best suited for driving or general use when depth perception is not as important as true color perception.
• Blue and purple lenses are not recommended for any use other than fashionable as the color actually serves to increase the contrast-destroying characteristics of blue light.
