Sunglasses, also known as sunshade mirrors, are used for sunshade. People usually adjust the luminous flux by adjusting the pupil size in the sun. When the light intensity exceeds the adjustment ability of the human eye, it will cause damage to the human eye. Therefore, in outdoor activities, especially in summer, it is necessary to use sunshade mirrors to block the sun, so as to reduce the fatigue caused by eye adjustment or the damage caused by strong light stimulation. Sunglasses block unpleasant glare while protecting your eyes from UV rays. All thanks to metal powder filters that "select" light as it hits it. Colored glasses can selectively absorb some of the wavelengths that make up the sun's rays because they use very fine metal powders (iron, copper, nickel, etc.).
A common problem with sunglasses is back glare, which occurs when light hits the back of the lens and bounces back into your eyes. The role of the anti-reflective protective coating is to reduce this reflection of light by the lens. Like scratch protection, the anti-reflective coating is a very strong, thin layer on the lens. The refractive index of the antireflection coating material is between that of air and glass. This makes the intensity of light reflected from the inner and outer surfaces of the film nearly equal. When the thickness of the film is about a quarter of the wavelength of light, the light reflected from the inner and outer surfaces of the film cancels each other out through destructive interference, minimizing the glare you see. Anti-reflective coatings are also applied to the front surfaces of refractive contact lenses and some sunglasses to eliminate "hot spots" created by the reflection of glare from the lenses.
