3. Anti-reflective coating - Wikipedia

   en.wikipedia.org/wiki/Anti-reflective_coating

   For the example of glass (n S ≈ 1.5) in air (n 0 ≈ 1.0), this optimal refractive index is n 1 ≈ 1.225. [20] [21] The reflection loss of each interface is approximately 1.0% (with a combined loss of 2.0%), and an overall transmission T 1S T 01 of approximately 98%. Therefore, an intermediate coating between the air and glass can halve the ...

4. Optical coating - Wikipedia

   en.wikipedia.org/wiki/Optical_coating

   Such coatings can reduce the reflection for ordinary glass from about 4% per surface to around 2%. These were the first type of antireflection coating known, having been discovered by Lord Rayleigh in 1886. He found that old, slightly tarnished pieces of glass transmitted more light than new, clean pieces due to this effect.

5. Smart glass - Wikipedia

   Smart glass, also known as switchable glass, dynamic glass, and smart-tinting glass, is a type of glass that can change its optical properties, becoming opaque or tinted, in response to electrical or thermal signals.

6. Mirrored sunglasses - Wikipedia

   en.wikipedia.org/wiki/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 through the tinted lens by a further 10 ...

9. One-way mirror - Wikipedia

   en.wikipedia.org/wiki/One-way_mirror

   One-way glass (4) used in a teleprompter. A one-way mirror is typically used as an apparently normal mirror in a brightly lit room, with a much darker room on the other side. People on the brightly lit side see their own reflection—it looks like a normal mirror. People on the dark side see through it—it looks like a transparent window. The ...
