I use Rudy glasses with changing shades and four different colors for differing conditions. They exceed shooting glasses/goggles requirements and are guaranteed scratch proof. They fully wrap around/shield my eyes. Also, they are the clearest glasses I have ever had.
In gun games it is not unusual to have splatter hitting you occasionally. One time I took a hard hit from the side, almost blew my glasses off and did leave a few big scratches in the lenses. Would have probably hit my eye........Rudy replaced them for free.
Don't go cheap with safety equipment.

Not cheap, but probably cheaper than a glass eye!
