What are two examples of practical applications of polarization?

One to be able to see 3D movies in full color (think IMAX), the other in sun glasses to eliminate the glare off reflecting surfaces (windows, water)

Hi. Astronomers use polarized filters to study deep sky objects. Light from some areas of the sky have unusual polarization which indicates where magnetic fields are located and how they are arranged. Also, amateur astronomers, such as I, use special moon filters with two polarized filters which can be rotated to dim the bright light from the moon to a comfortable level. Hope this helps.

Polarized sunglasses is one. When light reflects off the road or other horizontally aligned objects in front of you, it is polarized horizontally; therefore, vertically polarized sunglasses block out the glare from such things.

In addition to the above answers, polarized light is used to analyze stress and strain in structures using plastic models; it is also used in analyzing crystal structures. Optical microscopes often are used with polarizing filters.

I'd say the best example is probably liquid crystals displays...
