blue light hazard
Blue is a kind of high-energy visible light, can be directly through the cornea and lens, direct the macular area, accelerating the macular area cell oxidation, chemical damage to the retina, the retinal damage is more serious for children and Kang Mingsheng, said an official with the development of the main hazards are pathological myopia, cataracts, and macular degeneration eyes and harm body rhythm, existing related medical research shows that embodied in three aspects:
One is structural damage. Excessive blue light content of LED desk lamp is likely to cause atrophy or even death of retinal pigment epithelial cells, leading to vision loss or even complete loss. Moreover, it is an irreversible damage and will also lead to macular lesions.
The second is visual fatigue. Due to the short wavelength of blue light, the focal point does not fall at the center of the retina, but at a position further in front of the retina. The high proportion of blue light in LED table lamp will make users' eyes tense for a long time, thus causing visual fatigue, which may lead to deepened myopia, diplopia, easy serial reading and inability to concentrate and other symptoms.
The third is poor sleep. Blue light inhibits the production of melatonin, an important hormone that affects sleep and is known to promote sleep and regulate jet lag. Reading with LED lamps with high blue light content for a long time may lead to poor sleep quality and even insomnia.
LED desk lamps have been in contact with human eyes for a long time, especially under the current situation of the popularity of smart phones, the majority of users are teenagers. If the lighting composition and quality are not selected according to human's circadian rhythm, it is easy for users to have visual fatigue, and may even cause irreversible damage to human eyes. Kang Ming-sheng research and development, LED lamp should try to control the color temperature within 4000K to reduce the content of blue light, and strictly control the color index.
In addition, filter the blue light
