I spent $100 on some nice Specialized glasses with lenses that darken in bright sunlight and honestly, I find them too dark on cloudy days. I'd actually prefer some clear lens glasses for cloudy days or evening rides when I'm not riding into the sun. I don't really find that my eyes tear less with these glasses on high speed descents but at least they don't keep sliding down my nose when I've been sweating my ass off for a few hours.
