Wearing Effect Of Sunglasses And Polarized Glasses

Polarized glasses provide another mechanism for protecting the eyes. The reflected light on asphalt roads is a special type of polarized light. The difference between this reflected light and light directly from the sun or any artificial light source lies in the issue of order. Polarized light is formed by waves that vibrate in one direction, while ordinary light is formed by waves that vibrate in an undirected direction, creating a sharp contrast between a group of disorderly and randomly moving people and a group of soldiers marching with neat steps. Generally speaking, reflected light is a type of ordered light. Polarizing lenses are particularly effective in blocking this type of light because their filtering properties are at play. This type of lens only allows polarized waves that vibrate in a certain direction to pass through, just like combing out light. For road reflection issues, using polarized glasses can reduce the transmission of light because it does not allow light waves that vibrate parallel to the road to pass through. In fact, 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 polarizing mirror can face direct sunlight.
