I think eye protection with rifles isn't that important. Pistols on the other hand I think its essential. I shot my glock17 and beretta vertec M96 last summer and I can't remember with which pistol but I didn't wear eye protection and I got a nice blast of partially burn powder in the eyes that certainly was not pleasant. I have shot rifles for years and never had that problem but now as a precaution I wear sunglasses at the least when shooting rifle or pistol.
