Yrs ago they had a a dark tint I used to spary my headlights on a "mini truck"
I rode this weekend with it off and just the instrument cover and was surprised how much that little "screen" helped below 100. Over 100mph it doesn't matter as my nose is trying to escape through my visor

a can of flat black outdoor paint on the inside of the screen. spray in coats and save yourself $80 bucks or so.
