I agree with Luke, just look for a pair of safety glasses that does have the shield covering the sides of your eyes. Also, if you don't wear a hat normally already, wear one. On some ranges, the wall is not so high next to you and the shooter next to might hit you with his expelling casings. That is very distracting, especially when they are hot and hit your forehead right as you are pulling the trigger.
