I was looking for a pair myself, but I ended up going with a pair of Native multilens glasses in the end. The ones that change shade (phototropic?) all seemed very expensive and none of them got as dark or as light as I wanted.. I didn't look online, just in person at a few different stores, and in the end, I'm happy with my decision. Yah, it's not ideal to have to switch lenses, but it really doesn't take that long, and I'd rather have a true clear lens when I'm in the dark and a very dark lens when it's super bright out.
