My favorite routes generally include a lot of changing light conditions (sunny climb, shady descend). I've been wearing a pair of dark-ish sunglasses that doesn't allow a lot of light, which tends to cause problems on descends (I can't even see the pot holes in the shade!).

Since I wear hard contact (gas permeable) lens, getting anything in my eye causes a lot of pain. I'm thinking of carrying 2 pairs of sun glasses (one for bright light, and one for low light) situations, or 2 pairs of lens... albeit switching lens might be tricky with sweaty hands. Any TE'ers out there in the same situation?

Any recommendations or suggestions welcome :-)
