Regular sunglasses do not protect the eyes from reflected light. Only polaroid glasses with polaroid lenses can protect the eyes from such rays.
Polarized glasses prevent the appearance of visible light rays from various objects, thus improving image quality, increasing image contrast and generally having a positive effect on visual comfort.
Polarized glasses are designed to prevent light rays with horizontal polarity. Horizontal polarity is the reflection of light rays from the surface of objects. For example - the surface of the water, the surface of the snow, the surface of the asphalt, etc. Thus, polaroid glasses with polarized lenses provide better quality and comfort than with ordinary sunglasses.
