I am using wrap around safety glasses that fit pretty close (you know your stuff) and have tried pulling them as far away and down as possible, which has helped in the past, but I think there just isn't enough room between my face and the lens. Today I did some research and now I'm toying with the idea of retro-fitting a rotating drop-down visor to my helm. I have seen a couple instructional videos on it, but haven't read any success stories on BikeForums yet, but that's only because I haven't searched for it. I saw a great factory made version here but it costs over $900 because it's Gucci. Something cheaper must exist, maybe in the $150 range, and I would love to stop wearing safety glasses in general.
