Silent pipes take lives
I got around carrying a second visor by placing two parallel strips of electrical tape across the top of my clear visor. This makes it a lot easier to block the sun if it's low in the sky, and keeps the bright light of the sky out of my eyes the rest of the time.* Alternate visor. Since long rides usually involve different lighting conditions, I'll often bring my clear visor along in addition to the dark smoke that's usually on my helmet.
