The point of polarized lenses is to selectively block some light more than other light. As they apply to daytime conditions, polarized lenses tend to block light from surface glare much more than they block other light, because surface glare tends to be mostly polarized horizontally, while most other light tends to be equally distributed among all angles of polarization. Thus, by blocking horizontaly-polarized light, you block most surface glare, while blocking a much smaller portion of other light.
My idea is based on the notion that if direct light from headlights (which is the main source of night time glare) were polarized horizontally, then drivers wearing vertically-polarized sunglasses would have much more of that undesirable light blocked from entering their eyes, while having a much smaller portion of desired light reflected entering their eyes from things they need to see.
