Unlike lens for everyday vision, professional shooting glasses must protect your eyes from falling and flying debris. Having this protection on can also supply a shield from hazards during the cleaning of your guns as well.
The best shooting glass lenses are made from polycarbonate. Ensure that they have a military-grade rating and are rated by the American National Standard Institute. This makes them an acceptable standard for proper protection.
The lens color is also important. For low light conditions, clear lens is best. And, if you are shooting in areas where there is glare or other difficulties seeing, choose purple or gray lenses. Be extremely concerned with the fit. Lenses that slip or are not comfortable make shooting accurately difficult.
After ensuring the fit of your protective wear, watch your aim and enjoy the hunt. Your glasses are made to last many years, so use them well.
