Wear Effect Of Polarized Glasses

Polarizing glasses offer another mechanism for eye protection. The reflected light of asphalt is a special kind of polarized light. The difference between this reflected light and light coming directly from the sun or from any artificial source is a matter of order. Polarized light is made up of waves that vibrate all in one direction, whereas ordinary light is made up of waves that vibrate not in one direction. This is like the contrast between a crowd of people moving at random in disorder and a group of soldiers marching in orderly steps.

In general, reflected light is an ordered kind of light. Polarized lenses are particularly effective at blocking this light because of their filtering properties. The lenses allow only polarized waves that vibrate in a certain direction to pass through, as if combing light. For road reflections, the use of polarizing glasses reduces the transmission of light because it does not allow light waves vibrating parallel to the road to pass through. In effect, the long molecules in the filter layer are directed horizontally and can absorb horizontally polarized light. In this way, most of the reflected light is eliminated, while the overall illumination of the surrounding environment is not reduced, and the polarizer can face the sun directly.
