Generic, contoured non prescription sports goggles are acceptable if you don't require vision correction or if you wear contact lenses. These goggles have a slight wrap around the face and keep out wind and dust. The temples of shooting glasses often are designed with spring hinges that allow the frame to flex without breaking when recoil occurs. Temples also wrap around the ear in the "cable" style to help keep the frame in place, and the tips of the temples mayfeature rounded ends to enhance comfort.Nose pads are adjustable so that the frame rests in the optimum position, and soft silicone pads often are used for additional comfort. Some shooting glasses feature bridges that adjust to one of several locking positions so that the glasses are positioned just right for any shot.The frames are constructed of any number of ophthalmic materials, including titanium and other metals, regular plastic and tough poly carbonate. Eye protection is essential for anyone using a firearm, whether at a shooting range or in a forest or field or at work.All firearms have a certain amount of recoil, and many shooting activities take place outdoors where wind, sun and dust also can lead to eye and vision problems.Shotguns and rifles are held on the shoulder, while handguns are no more than an arm's length away. These different shooting activities occur in close proximity to the face, which means you should take every precaution to shield your eyes from harm.

Some range masters allow shooters to wear any kind of eye wear they like, but sometimes certain safety standards are required. This material has a high index of refraction.
