I saw a helmet at a dealer that came with an adjusting lense. You could not get a feel for it cause they had a colored sticker over the lense. I think it was an Arai but not sure. The price was real high too, like $500 or something.
I've heard bad things about them. Rider magazine tested one a while back, and I think they said it didn't get dark enough during the day or light enough for night. I think you'd be better off wearing sunglasses under your helmet and then just taking them off. That's what I do anyway. $500 visor or $100 pair of oakleys. And you can wear the glasses when you're not riding
