Years ago in FL my grandfather got some REALLY light tint on the windshield. Honestly, it was so light that you couldn't really tell that it was there, but since many, most of them do block UV light, it probably still helps. I would think that something like that might be OK and might slide past the cops, but most places don't allow anything on the front other than possibly a strip across the top. I like that for glare when the sun is low in the sky.

When the car is parked, I use one of those silver foil reflective sunshades which should work much, much better than a tinted windshield. That also makes it legal.
