Anti-radiation glasses are glasses with special anti-radiation function. They are used to protect the eyes from ultraviolet radiation. In the past, it was mainly used by personnel in special industries and required higher technology. Ordinary eyeglass manufacturers may not have this technology. Anti-radiation glasses, lenses can reflect or absorb radiation, but through a certain amount of visible light made of special glass. The lenses are coated with shiny films of chromium, nickel, mercury or silver that reflect radiation; Blue lenses absorb infrared rays, yellow-green lenses absorb both ultraviolet and infrared rays, and colorless leaded lenses absorb X-rays and gamma rays. Lenses can be used to protect against high - energy, short - wave blue radiation.
Radiation-proof glasses are suitable for use in front of a computer, with a high color resolution, and are suitable for wearing while watching TV. It can also be worn as sunglasses. It uses special technology to improve image contrast so it can be worn while driving according to EU regulations. People have paid more and more attention to the negative effects of computer on human physiology and psychology. For this scientific use of computer, reduce the harm of computer and network is very necessary. At the same time, we hope to pay attention to the care of the eyes while we continue to discuss whether the radiation glasses are useful. There are mainly the following aspects:
A, to enhance the awareness of self health care work gap pay attention to appropriate rest, generally speaking, computer operators in the continuous work for 1 hour should rest for about 10 minutes. And it is best to move the hands, feet and torso outside the operation room. At ordinary times to strengthen physical exercise, enhance physical fitness, to carry out regular physical examination and self psychological determination.
Two, pay attention to the work environment computer indoor light should be appropriate, not too bright or too dark, avoid direct light exposure on the fluorescent screen and interference light, the studio to maintain ventilation and dry, can make those harmful gases discharged as soon as possible, try to use non-impact printer to reduce noise.
Three, pay attention to the correct operation posture should be installed in the center of the computer screen and the operator's chest at the same level, the best use can adjust the height of the chair. When sitting, you should have enough room to stretch your feet and do not cross them, which can affect blood circulation.
Four, sleep enough, don't stay up late, drink more water, eat more fruits.
What is blue light radiation? Computer screen illuminant is composed by red, yellow, blue 3 primary colors. At present, it has been clinically confirmed that one of the main causes of macular degeneration is chronic light damage (mainly caused by blue light to the macular area of the retina of the eye). And, in particular, that. Blue light is especially harmful to children's eyes because their lenses are particularly clear. And the damage is irreversible. So children watching TV, playing computer eyes are particularly easy to damage. So to evaluate whether a pair of glasses has an effect on radiation protection, the key lies in blue light protection and anti-reflective coating. Blue - blocking glasses are also uv - blocking. In Europe, only glasses that protect against both blue and ULTRAVIOLET light can apply for certification. The antireflective coating reduces the frequency of the eye's continuous focus.
