Agreed. Wiley X frames can accomodate most perscriptions (unless you wanted to wear contacts instead). Unfortunately my eyes are so bad that I have to use glasses of some variety to correct it. But if you live anywhere near a military base or have friends that are in the military then you might try seeing (pun intended) if they will hook you up. I think on base the frames with standard sunglass lenses are somewhere in the $100 range.
I got some Wiley X SG-1 V cut goggles with smoke and clear lenses, elastic strap, sunglass thingies and case for $69 at Edwards AFB. I went back to see if I could get another set for someone but they had all sold out. Awesome goggles, I love them.
