Do you know polarized sunglasses can help driving?

The bright glare of the sun on the cars ahead can sometimes be eased greatly with the Polarized Sunglasses. They tend to be polarized horizontally, therefore ideal for vertically designer polarized sunglasses. The reason is that the surfaces you see on the car ahead of you (the back window, trunk door, and even the ceiling) is tilted toward you, as the sun will be more or less aligned in the vertical plane passing two cars (if not, could not see his reflection in that area). However, if the sun is relatively low behind you, the sun's rays will be nearly perpendicular to the reflection (vertical) surfaces that do not polarize light. The sunglasses will help more with reflections from the glass by the metal as the former are polarized to a degree higher.

What happens to the brightness of the road itself? This light is partially polarized, but the dispersion (as opposed to reflection). The direction of polarization will change with the direction of the road in relation to the position of the sun. The rule is that the polarization is tangential to a circle centered on the sun. This means that if the sun is in front, behind or above the brightness of the road tend to be horizontally polarized filter Sunglasses provide some help. However, if the sun is on one side, the polarization is rotated vertically, the more the lower the sun happens to be. Of course, if the road is wet to get the same anti-glare power than at sea.
