And a speech pointed out that the service life of the human eye is 50 years or so, starting from the age of 40 crystalline turned brown and automatically block blue light, so after age 40 more lens cataracts. Instead, young people’s crystalline clear, stop the blu-ray ability is poor, may be seriously affected by the blu-ray.
Talk about blue light influence on the clock function, under the blue light is indispensable to human. Sunlight will contain more blue, the sun rises every day, shine blue light, make the human active wake up, the sun is setting, blu-ray, less melatonin in the human body, induction of human sleep.
But in recent years, along with equipped with LED back light electronic products and the popularity of LED lighting, the eye clock exposure under blue light. This is likely to disrupt the rhythm of life based on the function of the body (circadian rhythm).
Professor at keio university of ping tian pointed out: “recently, the researchers found the absorption peak of blue light wavelength called ‘third depending on the cells’ of cells, and found that the cell controls the circadian rhythm.” There is no question of body absorbs a large number of blue light during the day, but at night continued to be exposed to blue light. In the evening continued to watch blu-ray, “the body will be mistaken for ‘or'” during the day.
Verify the blu-ray long-term effect will take a long time, and now electronics users have begun to wear the blue glasses. Sliney Johns Hopkins university professor in the institute on said: “while wearing the blue glasses is not required, but there is no reason to deny a user to be on the safe side and equipped with blue glasses.”
