Basic knowledge of sunglasses: the mechanism of eye tissue damage caused by radiation

u003cbru003eIn addition to reducing the radiation intensity of visible light, sunglasses can also reduce ultraviolet and infrared radiation. Polarized sunglasses can also be used to eliminate horizontal reflections on water, snow, and gravel roads. Sunglasses are now more fashionable. But the fundamental role of sunglasses is to provide radiation protection for the eyes. Recommend sunglasses 9001 guns, stylish and cool, highlighting the unique charm of the individual. The mechanism of radiation-induced damage to eye tissues (1) Thermal effects When exposed to long-wavelength radiation sources for a long time, local tissues will have thermal effects due to the increase in molecular motion rate and temperature. Longer wavelength radiation photons have lower energy and usually do not cause damage to eye tissues. However, in high-intensity low-energy long-wave radiation environments, such as some high-temperature occupational environments (blast furnaces and glass workers, etc.), infrared (IR) Can cause damage to eyes. (2) Photochemical effects Short-wavelength radiation damages the eyes, especially the damage to the lens and retina. The shorter wavelength radiation photons have higher energy, which may break the chemical bonds of local tissues and destroy the molecular structure, thereby causing local eye tissue damage. Generally, for eye tissue, short-wavelength UV radiation is more harmful than wavelength IR radiation. (3) Draper's law Radiation damages the eye when it is absorbed by the eye tissue, and only the part of the incident energy absorbed by the system can change or affect the system. If the radiation can directly penetrate or be reflected without being absorbed by tissue molecules, it will not affect the tissue. This principle is called Draper's law.
