Windscreen glare.

[ADV_93]

Does anyone know of anything that can lower/eliminate the glare you get through a windscreen at night? It's almost as though every car going the opposite way has had its headlights set so they point directly at my face and light full bore. Very distracting and i pray the next car doesn't have xenons...

I've seen spray on stuff on the internet but can't find anything on the matter.

Any advice welcome, thanks!
