After my share of burns and some real close calls (ever get a hot empty trapped between your eyeglass lens and your eyelid, I have), I found a solution. Wear long sleeve shirts to the range. Many manufacturers sell nice long sleeved shooting shirts with the logos of your favorite gun on it. Hats are also important to those of us that wear prescription eyeware (see above). I realize this will cut down on "macho" burn scars but it does work if you are fond of your skin. I still shoot in a T-shirt but thought some might like this advice.
