My vision is bad enough, I don't want to mess with the lens. I like to think my helmet has the "windshield wiper" effect from Republic Commandos.
As for the weathering, it is weathered but it's subtle, it just gets washed out by the flash. Jun and Jonich have seen it on my webcam so they've had the best view of it aside from seeing it in person. Jun, Jonich, can I get a witness?
