Polarized light

Polarized light is light that has passed through a polarizing filter. It's special property is that these light waves vibrate all in a single single plane as opposed to "normal" light where lightwaves are rotated around countless angles. Polarizing filters are called polarizers. They are made of long molecules that are lined up in one direction, so only lightwaves that match the alignment of those molecules can pass through.

Polarized light is often used in imaging technology to create sharper images and eliminate optical distortions.

Polarizing sunglasses are used to reduce glare[?] from sunlight reflected on surfaces.

Polarizing filters are used in liquid crystal displays to convert their modulation of polarization into the modulation of light intensity.

Polarized filters were first produced and patented by Edwin H. Land, founder of the Polaroid company; see also Polaroid®.

This needs to be merged with linear polarization.
