The WHO WHO Eye Association announced that from 2006 to 2008, more than 30,000 people worldwide were blinded by blue light and radiation, and an orange warning was issued at the end of 2009: "The potential hidden threat of blue light and radiation to humans will far exceed that of Sudan. The destructive nature of red, melamine, SASI, and HINI devours both eyes invisibly.
According to the data of the Chinese Medical Association Ophthalmology Branch, among the 420 million Internet users in China, 63.5% of Internet users have different degrees of eye diseases due to blue light, radiation loss, cataract, and blindness.
First, why do you use the three primary color table lamps and computers for a long time, and the eyes will have symptoms such as fatigue, dryness, and tingling?
The main reason is high-energy short-wave blue light
The white light emitted by the light source of the three primary color table lamp can form a blue light excitation phosphor mainly by a wavelength of 450 to 455 NM, wherein the lower the wavelength, the stronger the firing ability. Generally, the factory wavelength of the three primary color light sources is controlled within 500 NM, generally 450 to 455 NM or 455 to 460 NM, which are among the most radiation-damaged sections. If the wavelength becomes large, the ability to excite the phosphor decreases, and the luminous efficiency decreases. In order to pursue brightness, the manufacturer usually strengthens the blue light intensity of the three primary color light sources. If the human eye looks at such a light source for a long time, it is inevitable that the eyes will be damaged by blue light.
All these uncomfortable symptoms are a sign of self-protection of the eye. These signals mean that the eye is already hurt and needs protection. If we ignore these symptoms, the consequences are further damage to vision, which is usually drug-free.

Professor RHW Funk's research report from German ophthalmologists pointed out that when "inappropriate light" continues to illuminate our eyes, it can cause dysfunction, especially LED lights, computer screens, etc., which contain a lot of irregularities. High-energy short-wave blue light of frequency. These short-wave blue light have extremely high energy and can penetrate the lens to reach the retina, causing photochemical damage to the retina, directly or indirectly causing damage to cells in the macular area.
Therefore, for normal people, blocking long-time exposure to blue light is the most effective way to reduce damage, and the use of anti-blue light glasses can effectively solve this problem. Ordinary radiation-proof glasses can only filter ultraviolet rays and certain electromagnetic radiation. Cannot filter blue light. Special anti-Blu-ray glasses can not only effectively isolate ultraviolet rays and radiation, but also filter more than 90% of blue light. It is suitable for use when watching a computer or TV. It can greatly reduce the stimulation of blue light on the eyes and eliminate the symptoms such as soreness, fever or pain in the eyes. Relieve eye fatigue.
