At our range, the RO lets a lot of people just wear regular sunglasses. I guess if you want to look cool go ahead, but I have a pair of S&W Code 4 sunglasses that meet ANSI Z87.1? but are also shooting glasses.
As for ear protection - I use ear protection when working on my car. I hate it when I'm grinding, cutting, torching/welding, or using the air compressor because it hurts my ears. I slap on a pair of earmuffs designed for this and its OK.
For shooting I wear 33 dB NRR Silencio foam ear plugs. I could not find a pair of large ear muffs that have comparable noise reduction specs, plus for some odd reason the ear muffs always hit the buttstock when I'm shooting.
I love shooting with my ear plugs because 7.62x39 and .223 sound like puffs rather than explosions. But there's always these jacka$$es at the range with HIGH CALIBER hunting rifles and large caliber blackpowder guns that sound like thunder right next to you even with ear protection.
I can no longer shoot at the 100yd or 50yd line because of these shooters - and they ALWAYS want to crowd together with other people.
Just the other time I had to go to the 25yd range because of their guns and these two yahoos come over with their bolt-action whatevers that sound like my .223 times 100.
I wish they'd slap some type of noise suppressor on their rifles because it hurts my ears.
And don't get me started on muzzle brakes that shoot powder residue sideways... it goes RIGHT into my face because of the proximity between shooters (about 2').
I come home with a headache from the loud high caliber hunting rifles, everything tastes like gunpowder, and my hair is full of gun powder residue.
That blackpowder crap is also very nasty.
