LOL, trying to catch up with Root's post numbers eh?

Are your side windows tinted? If not can they be? Actually not to be a dick I would have to agree with the sunglasses recommendation, especially wrap around glasses. They tend to block side glare a lot better (obviously) than regular frames that have a large gap on the side.

I've seen those suction cup mesh style sun blocks but they look fugly but I guess if you routinely drive with side sun glare it might be worth considering.
