The best color for shooting glasses will depend on what time you are shooting. Many people are comfortable in yellow and orange tinted lenses for shooting, as these can block haze and blue light, and even enhance the contrast between the target and its background. A yellow lens also works better if you are shooting in low-light conditions. A gray tint to the lens will not enhance the target, but will provide a reduced glare in bright sunlight, which makes this good if you often are in a sunny range. Certain lenses are polarized, and they can come in any color, even clear. These are great to have for reducing glare and enhancing your outdoor vision. Some shooting glasses change color by darkening automatically when in bright sunlight and come in a variety of colors from brown to gray and green. The coloring is again something that is relative to the shooter and what they prefer.
