    As you hopefully know, we can think of light as a wave. Ordinary light, such as from the sun, is unpolarized. This means that the waves are oriented in all directions around the axis in which the light is traveling. That's the light at the left of this picture. Polarized light, by contrast, has the waves all oscillating in one direction. You can see in the diagram how the unpolarized light passes through a filter which selects for just the light oscillating in the vertical direction. The last filter in the diagram selects for light waves oscillating horizontally. As there are no more such light waves, that second filter stops the vertically polarized light.

    Light reflecting off horizontal surfaces are often horizontally polarized. If you want to reduce road glare when you're driving, we often wear sun glasses that have a polarizer in the vertical direction which filter out the horizontal light. See this diagram.
