When you live somewhere the sun is actively trying to kill you 7+ months of the year a tinted windshield does wonders. I have one on my car and I couldn't tell you the difference between my night vision with the tinted windshield versus untinted. If I can't see in front of me with time to stop with the light my low beams give, I'm driving too fast.

It does nothing to stop the glare from the massive trucks with the headlights deliberately aligned to shine directly into a passenger car's cabin. Anyone who drives at night with a tiny that dark is a danger to the public and belongs in the same camp the F350 eyemelter owners end up in for their crimes.
