Gargoyles are my #1 choice, high quality and not as pricey as many brands. I have worn those for driving, motorcycling, and flying (as pilot). I also have a pair of American Optical "original pilot" sunglasses and some LL Bean sunglasses that have served quite well, both get used all the time for driving. I personally prefer polarized lenses and tan vs. gray for driving, though gray is better for color accuracy.
But honestly, for outdoor work I usually wear $7.99 gray tinted safety glasses from one of the big box hardware stores. They are mostly/all marked as having 100% UV protection, which is important but also pretty much standard these days. As an added bonus, the safety glasses are highly impact resistant (that's the point) and also very cheap. I find their optical clarity pretty good; not as good as my Gargoyles, but up there with others I have. You could buy 3 pairs and have spent much less than any one pair of a high end brand. I sweat a lot working in the sun and I have no qualms about washing those with soap and water when they get icky. I can get a couple years out of a pair, which for $8 is to me a great deal.
