Exclusive model of wooden polarized glasses from the VeyRey collection UV filter 400 universal size How does the POLARIZATION FILTER work? 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 surface, 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. It is precisely to suppress this negative effect of horizontal polarization that a polarizing filter and polarized glasses are used.   % Width of the front of the glasses: 14 cm Height of glasses measured in the middle of the lenses: 4.9 cm Leg length: 14.5 cm Material type: natural materials Lens tint: black
