2. Mirrored sunglasses - Wikipedia

   en.wikipedia.org/wiki/Mirrored_sunglasses

   A person wearing mirrored sunglasses. Mirrored sunglasses are sunglasses with a reflective optical coating (called a mirror coating or flash coating) on the outside of the lenses to make them appear like small mirrors. The lenses typically give the wearer's vision a brown or grey tint. The mirror coating decreases the amount of light passing ...

3. Sunglasses - Wikipedia

   Mirrored coatings can be made any color by the manufacturer for styling and fashion purposes. The color of the mirrored surface is irrelevant to the color of the lens. For example, a gray lens can have a blue mirror coating, and a brown lens can have a silver coating. Sunglasses of this type are sometimes called mirrorshades. A mirror coating ...

4. Fresnel equations - Wikipedia

   For non-magnetic media we can substitute the vacuum permeability μ 0 for μ, so that = ; =; that is, the admittances are simply proportional to the corresponding refractive indices. When we make these substitutions in equations ( 13 ) to ( 16 ) and equations ( 21 ) to ( 26 ), the factor cμ 0 cancels out.

5. Brewster's angle - Wikipedia

   en.wikipedia.org/wiki/Brewster's_angle

   Polarized sunglasses use a sheet of polarizing material to block horizontally-polarized light and thus reduce glare in such situations. These are most effective with smooth surfaces where specular reflection (thus from light whose angle of incidence is the same as the angle of reflection defined by the angle observed from) is dominant, but even ...

6. Polarization (waves) - Wikipedia

   en.wikipedia.org/wiki/Polarization_(waves)

   Polarized light with its electric field along the plane of incidence is thus denoted p-polarized, while light whose electric field is normal to the plane of incidence is called s-polarized. P-polarization is commonly referred to as transverse-magnetic (TM), and has also been termed pi-polarized or π-polarized, or tangential plane polarized.
