To clarify, my regular lenses are vertically very narrow, almost like Ben Franklin or granny glasses. The ones I use for riding are only slightly larger. If you like, I'll take pics & post. You'd be surprised how small the difference. Before I tried them the first time, I wasn't even sure they would work. I'd say I ride fairly low on the drops, FWIW. Take a look at my avatar. For those that like data, my bikes are set up with the sitbone part of the saddle typically 3-4" above the top of the stem.
