Sunglasses are a kind of vision care products to prevent the damage to human eyes caused by strong sunlight. With the improvement of people's material and cultural level, sunglasses can be used as special accessories for beauty or personal style. Our eyeball (lens) is very easy to absorb ultraviolet rays, and the damage of ultraviolet rays to the eyes is invisible. In order to protect the eyes, we must always wear sunglasses. Ophthalmologists recommend that you must always wear sunglasses to protect your eyes; this is because our eyeball (lens) is very easy to absorb ultraviolet rays, and the damage of ultraviolet rays has two prominent characteristics: 1. The damage of ultraviolet rays will accumulate. Since ultraviolet light is invisible light, it is difficult for people to perceive it intuitively. 2. The damage of ultraviolet rays to the eyes is irreversible, that is, irreparable. Such as: cataract surgery can only be replaced by intraocular lenses. Long-term damage to the eye can easily lead to damage to the cornea and retina, clouding of the lens until cataract occurs, resulting in permanent visual damage.
Polarized sunglasses block unpleasant glare while protecting your eyes from UV rays. All thanks to metal powder filters that "select" light as it hits it. Polarized sunglasses 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.). In fact, when light hits the lens, it is eliminated based on a process called "destructive interference". That is, when certain wavelengths of light (in this case ultraviolet a, ultraviolet b, and sometimes infrared) pass through the lens, they cancel each other out on the inside of the lens, toward the eye. It is no accident that the overlapping waves that make up light waves: the crests of one wave combine with the troughs of its adjacent waves, causing them to cancel each other out. The phenomenon of destructive interference depends on the index of refraction of the lens (that is, the degree to which light rays deviate from the air as they pass through different substances), and also on the thickness of the lens. In general, the thickness of the lens does not vary much, and the refractive index of the lens varies according to the difference in chemical composition.
