Polaroid filters block light traveling in the horizontal plane. Essentially, the filter only allows light that's traveling vertically to get past the lens. Polaroid filters are often used on sunglasses.

Polaroids are the collection of micro crystals that are used to control the propagation of light. As we all know, light is a wave that propogates with a speed of 3 x 108 m/s. It vibrates in all direction. If a light passes through a Polaroid, light polarised parallel is absorbed, and only the light polarised perpendicular are transmitted.
