For General Purpose use, the Dark Grey/smoke lenses are the most popular. They do not distort colors, they reduce glare to provide day-long comfort, and reduce ultraviolet (UV) light to a safe level. If you go to an eye doctor for a sunglass prescription, he'll most likely recommend Dark Grey/smoke lenses for general purpose use. The Military has been using Dark Grey/smoke lenses for over 45 years. However some other lens colors can provide sports specific attributes.
Lens Tints and Coatings
Smoke, Gray and Gray-Green tints:
The most common type of lens colour. Transmits all colors evenly without changing value of color. Light enough not to impair vision, yet dark enough to provide overall protection from glare. Excellent for bright sunny days. Grey tint is best for bright light situations like water sports because it blocks out the brightest of the suns rays.
Dark Amber or Brown lens tints:
A warmer, slightly brighter lens than the gray. Especially good at blocking the blue light commonly found in diffused light such as one might experience on a cloudy day. Brown/Amber can improve both contrast and depth perception, reduce glare and is a good all-around choice if you live in an area with changeable weather patterns. Brown is great for applications where distances need to be constantly judged, like tennis or golf or skiing or other sports requiring acute visual perception and contrast differentiation. Brown is also best for lower light situations, like fishing in the late afternoon or early morning. Brownish tint lens helps highlight the different contrasts in green colors and enhance visual acuity on the golf course.
Yellow Lens Tints:
Improves contrast, reduces glare, perserves sharpness. High Intensity tint for maximum sight performance during low light driving. Excellent for Night riding, overcast, haze, or fog conditions. The brightness of this lens makes it the choice of many mountainbikers, shooters and cross-country skiers. Yellow enhances contrast by filtering out the somewhat scattered, out-of-focus blue light from the scene. Hunters, pilots, and tennis players find them helpful for this purpose.
Help block blue light, thereby improving contrast. Offers high contrast and very soothing to the eyes. Improves road visibility. Many people feel that rose tinted lenses are more comfortable for long periods of time than other lenses. Great for computer users to reduce eyestrain and glare.
Blue-tinted lenses are endorsed by the USPTA for tennis professionals and were provided to linepersons in the 2000 French Open. Blue is a contrast lens and reduces glare from visible white light (such as light reflected from mist, fog, snow, water).

What is Flash Mirror?
The wearer perceives no difference in vision regardless of what color the coating is. Only those looking at the person wearing the glasses can see the color of the mirror coating. Mirror coatings are generally applied over sunglass-dark lenses. Obviously, a highly reflective flash coating prevents others from seeing the eyes of the wearer.
Flash Mirror sunglasses feature idiflect multi-layer vacuum deposition mirror on polycarbonate lenses, which are designed to absorb more light than uncoated lenses and enhance visual acuity using an optical-grade polycarbonate material and superior hard coating. Lens comes with a light mirror finish added to the outside of the lens, but is not completely a mirror look.
