• I use prescription / photochromic lenses.
    The challenge is getting frames that work in an aero position. I went to the opticians and tried all their frames with my head down, looking through the top of them, and found some ones that had virtually no bar visible at the top.
    Only problem is when it rains really hard, esp at night, and glasses are useless. It doesn't happen often but I've thought of carrying a couple of disposable lenses to use then. Chances are I wouldn't bother faffing with them in those conditions though, just take the glasses off and hope not to hit anything big.
