Engaged in the IT industry for a long time facing the computer, children always watching TV at home, holding mobile phones all day long online... Consumers choose the anti-Blue-ray glasses for a variety of reasons. But do you think that the glasses you bought really prevent Blue-ray?
According to the director of the Visual Health and Safety Protection Laboratory of the Institute of Standardization, the anti-blue glasses on the market now block or absorb blue light through special materials. At present, there are two misunderstandings in Blue-ray protection. One is that the defense is not protected, and the other is the visual fatigue caused by the color shift caused by false protection.
"The blocking rate of anti-Blue-ray glasses is 20%-30%." Expert said that the blocking rate of anti-blue glasses on the market has basically reached 80%-90%. However, the band of the protection is not protected, and the high blocking rate also causes color shift, which makes it easier for the eyes to fatigue.
Experts who have been engaged in refractive research for many years say that they never actively recommend patients to wear anti-blue glasses. He also does not advocate the use of anti-blue glasses as a "altitude", and wears them in an uncontrolled manner. He pointed out that in the winter, the air is dry, normal people do not use computers, mobile phones and other products, and the eyes will appear dry, so it is more important to use the eyes and protect the eyes than to wear anti-blue glasses.
