Consequently, some sort of hearing protection is usually considered mandatory by most shooters. Any kind of hearing protection is better than nothing. In terms of effectiveness, most folks seem to feel that muffs are more effective than plugs, but they cost more, too. The electronic muffs also make great Christmas, birthday, and anniversary presents. Generally, the more you pay for your hearing protection, the more convenient and effective it is.
Many ranges require some sort of eye protection for everyone, both shooters and spectators alike.
In my opinion, those that don't should. Plus you can't rule out a gun or ammo malfunction that could send hot gas or powder fragments towards an eye. These can be safety rated sunglasses, actual shooting glasses, or even prescription glasses for those among us who don't see as well as we used to. As with anything else, you get what you pay for when it comes to eye protection. Some shooting glasses are made to withstand the impact of a .22 LR round at just a few feet.
