There is a good deal (from what it seems) on these with black frame and 2 lenses (clear and smoke). $37 shipped. Are these good glasses? I need some new ones.

Link?

Its on Gearhog today. Hope I am not breaking any rules by saying that.

Smith's higher end glasses are very nice.  I have a pair that I use for skiing.  For ballistics though, you are much better off going with Revision Eyeware.  You can either use the 30% discount "ar15" on their website, or you can find brand new ones for sale on the EE and on lightfighter for $25-35 for the kit that has clear and smoke lenses.  I have a couple of pairs of the sawfly's, and one pair of the hellflys.  The are excellent glasses and have the highest ballistic rating in the industry.  They stop bird shot at 7 feet distance!  You can see their youtube tests as well.
