X LOOP Polarized Wrap Around Fishing Driving Cycling Golf Sunglasses - Clear & Black

I can put prescription glasses on

is it one size fits all???

So are the clear black polarized? It says they are, but when you click on black it pulls up grey lens? Thanks

How are these for night time driving, I'm sick of headlight glare but I don't want something that's too dark? Also what color lens for night driving?
