Is blue light blocking eyeglasses effective？
Blue Ray Blocker are coated with a special material film on the surface of the glasses. This kind of film can prevent radiation.
However, radiation-proof glasses do not protect against all radiation.
The radiation of computers is mainly electromagnetic waves, but electromagnetic waves have certain wavelengths, and the wavelengths filtered by each radiation-proof glasses are different.
Therefore, it is hard to say whether the anti-radiation glasses you spend money on match the radiation wavelength generated by the computer you are using.
The role of blue light blocking eyeglasses：
1. Computer safety glasses are made from the world's high-tech vacuum ion coating.
It can block electromagnetic waves and has no side effects on vision.
2. The lens contains anti-radiation substances.
It can absorb low-frequency radiation microwaves and eliminate potential fever, headache, fatigue, dryness and other adverse symptoms of eyes caused by electromagnetic wave radiation.
3. For computer workers, as well as friends who like watching TV and playing video games.
Radiation-proof glasses can effectively prevent harmful light from damaging eyes and protect eyesight.
4. Computer light blocking glasses have different penetration and absorption functions for different light.
It can resist reflection and anti-glare, and the user feels clear and natural after wearing.
The use of anti-blue lenses
Blue light is one of the factors that affect eye fatigue. Anti-blue light glasses can protect eyes to a certain extent, especially for groups who stare at electronic screens for a long time.
However, when selecting Blu-ray glasses, it must be noted that the glasses must have an authoritative detection mark.
The wavelength range of visible light in nature is 770 ~ Between 390 nanometers.
Different wavelengths cause different color feelings of the human eye, such as 600 ~ 700 nm, feels red; 500 ~ 600 nm, feels yellow;
And 400 ~ 500 nm, it feels blue.
The shorter the wavelength of physics, the higher the energy and the stronger the penetrating power. For example, the harm of ultraviolet rays to human eyes is confirmed, but the harm of blue light to human eyes is not much studied in China at present.
In foreign countries, especially Germany, there are many types of research on this aspect.
Relevant research results show that blue light has been proved to be the most harmful visible light.
Blue light can stimulate an abnormal retinol in the retina and generate a large number of free radical ions, which increase the damage of retinol to retinal pigment epithelium, thus causing atrophy of retinal pigment epithelium, then cause the death of light-sensitive cells, and the death of light-sensitive cells will lead to gradual decline or even complete loss of vision.
Computers, mobile phones, Yuba, projectors, laser pens, fluorescent lamps, LED flashlights, etc. , all have certain blue light, which has a certain impact on vision, such as staring at mobile phones or computers for a long time, the eyes will feel dry, tired, sore, etc.
However, it must be noted that blue light is only one of the factors that form these problems. In addition, it also includes many factors such as electromagnetic radiation, flashing screen of the screen itself, long-term inattention of eyes to rest, etc.
Wearing anti-blue ion glasses can effectively prevent blue light from damaging eyes.
Keep your eyes away from dryness, fatigue, soreness, etc!
