Hunters who wear glasses may need a little extra help from their optometrist when it comes to keeping their vision on target.

According to the American Optometric Association, regular eyeglasses may do more harm than good for hunters because the prescription may not be set high enough in the lens for sighting the gun.Also, the association says, glasses with small lenses or thick frames and wide temple pieces can hamper side vision, which is used to detect motion.

However, it adds, hunters who tell their optometrist about their sport can get frames and lenses specially suited for hunting and may also pick up a few tips that will not only help them see game better against the brush, grass or sky but help them safely aim and hit that game.

For example, hunters are advised to consider yellow-tinted lenses because dim sunlight reduces contrast between the game and its surroundings.
