Light travels in space in waves that oscillate in all directions of the optical medium. If it is reflected from a shiny non-metallic surface (glass, snow, water, etc.), the light becomes polarized, that is, its waves travel in only two planes: horizontal and vertical. Vertically polarized light is very useful for our eyes. It allows you to see in contrast and color, while horizontally polarized light creates annoying glare and optical noise. To suppress this negative effect of horizontal polarization, a polarizing filter and polarizing glasses are used.%Material Type: Plastic Lens colour: red
