How do polarizing sunglasses work?
Sunglasses work by placing pieces of tinted plastic polymer in front of your eyes. Light at all frequencies (from Infrared, visual, and Ultraviolet) coming from the sun hits the lenses and they act as a filter absorbing certain frequencies in certain amounts and allowing others to pass through. "gray" sunglasses are neutral and thus absorb all frequencies of visual light in equal amounts where as "rose tinted" glasses absorb more of the frequenceies that make up green, blue, indigo, and violet, and allow mostly red, orange and yellow to pass through. This can distort your perception of color outside the glasses so I don't recommend any colored glasses be it pink, brown, green are anything else. It's a misconception that only polarized lenses can block Ultraviolet light however it is true that usually cheap glasses do not. Even if they say "block 100% of UV rays" you may want to ask if it blocks 100% of UVA, UVB, and UVC rays because most cheap glasses only block UVC rays which are harmless. Polarized lenses are made of special polarized plastic which can block polarized light reflections (or glare) from sources such as water or the atmosphere itself.
How can you tell if sunglasses is polarizing?
Instead of rather a complicated and scientific method, you may simply figure it out with two pairs of glasses. Specifically, hold up both lenses and try looking through them both, then rotate one pair 90 degrees. If the sunglasses are polarized, you will not be able to see through these two lenses once you do this. If you do, one of the lenses is not polarized. What's more, try ooking through your lenses (holding them in your hands away from your face) at a window, TV screen or lake with intense glare. Rotate the glasses in a circle facing the glare. The intensity of the glare should change when you rotate your glasses; otherwise, it's not polarized.
Polarized sunglasses work by?
When light reflects off flat surfaces, such as pavement or water, it becomes polarized. This means that instead of scattering in all directions, it travels horizontally. Humans experience polarized light as glare. Polarized sunglasses block polarized light with vertical filters that prevent horizontal light from passing through. Only light traveling vertically can pass through the vertical filter.
What is the difference between self-tinting sunglasses and polarized sunglasses?
Polarized sun glass lenses are made to neutralize the effect of glare. A 'glare' is caused when the sun's shining rays reflect off a solid surface or water. A 'glare' is typically horizontally polarized. And the lenses are made of vertical polarizes so that they will effectively neutralize the villainous glare! Advantages of Polarized Sunglasses: Polarized sunglasses are specially made for reducing the harmful effects of glare and eye-damaging light. And they are a perfect boon, for all your outdoor activities. http://www.sunglassreplicas.com/Polarized_Sunglasses_s/50.htm i don't know much about self-tinting sunglasses.

Will sony Bravia 3d glasses work in movie theatre I have two pairs and was going to see Prometheus. Wondering if those glasses will work there instead of the cheaper ones supplied at the theatre?
Though I've never tried, I don't think they will because the technology is different. 3D glasses in a theater are polarized. Two synced projectors throw images with slightly different perspectives up simultaneously, but at different polarizations. The polarized glasses only allow a single corresponding polarized image into each eye, and the brain does the hard work again, combining two separate images into a single 3D one. Sony uses active shutter glasses. They actually block vision alternately in each eye, synced with the refresh rate on the display. The glasses rapidly darken each lens while the display alternately shows images with a slightly different perspective.
