If you want cheap and durable, look into safety glasses with tinted lenses. I wear Jackson (now KleenGuard I think) Nemesis VL all the time for farming, outdoor adventures, and everything else... they've held up really well and mine definitely aren't babied.
I'm not sure you can get the VL polarized, though, if that's important. The original Nemesis has a lot more lens variants but I like the fit of the VL quite a bit better, personally.
