I’ve got a full-face helmet with a clear flip up sunshield and no visor. For daytime riding, I ride with my sunglasses on, too. Can anyone suggest what I might do about sun glare in the early-AM or late-PM when the sun is low in the sky? I think my neighbor has blacked out the top of his shield with tape on the inside, and then he rotates the shield up and down to block the sun when it is low in the sky. Seems like a very basic approach. Is there anything better?
