You want maximum eye protection. Eye glasses are not enough. I wear prescription glasses and I had a special pair of sunglasses made. They are my driving glasses and they are safety rated. I get them at America's Best. Check them out.
If you do get something, get it from a optometrist to your prescription and with yellow lenses. He can provide you with side shields, etc. Just tell him what you want them for. They are relatively expensive, but you can save a couple bucks on a inexpensive frame. Off the shelf goggles are (usually) not optically non-distorting, or made for shooters, and will mess up your accuracy.I use standard eyeglasses (plastic) when shooting center fire and rim-fire guns.
Is this OK, or should I consider another layer of protection?
My local range (owned by the state government) does not have any rules on what eye protection should be used and many shooters do not use any eye protection on the range.
Do you take any extra precautions when using reloads?
That same reason (several 45 brass and a couple of 22 brass, I was a slow learner) that I switched from the uber cool sweat bands most of the shooters was wearing to a ball cap like my coach was wearing. No more hot brass on my eyelids.While I have plastic shatter proof lenses in my regular eyeglasses, I generally also wear some amber over-the-glasses safety goggles. I plan to ask my optometrist to work with me to get a good pair of prescription shooting glasses.
Recently it was reinforced to me how well eyewear with some additional shielding can help. One day when I did not wear the goggles, a spent (very hot) 9mm case hit me in the forehead just above my right eye and dropped down behind my eyeglass lense. Even though I immediately jerked off my glasses to drop the brass, it burned me pretty good just below the eye. That was a sufficient reminder for me to get my goggles back on.
