Prolonged exposure to blue light emanating from our phones, computers and many other appliances that may adversely affect the duration of human life. Scientists assume that blue wave which emanates from the LEDs, damage brain cells and retina, even in the absence of direct incidence of the rays of light. Scientists have conducted a number of studies on the common fruit fly, which it turned out that the light wavesthat are emitted when burning LEDs, accelerate the aging process.
Harmful blue light?
Light is electromagnetic radiation, each color which has a definite amount of energy. At the beginning of the light spectrum is red, which has low energy and is easily perceived by the human eye, closer to the top of the spectrum is the blue light that has great energy and is able to penetrate into the retina, quickly tiring our organs of sight.
Artificial blue light that comes from the modern gadgets and devices, is the most harmful part of the spectrum, whose wavelength is between 380 and 500 nm. Light waves of this range are the shortest of the visible light, the most actively dissipating.
Scientists have long confirmed the negative impact of blue light on humans, but continue to carry out more detailed studies about its effects on the human body still and dwell on the information received do not plan to. So, scientists from the University of Oregon published the results of new research in the journal of Aging and Mechanisms of Disease.
In the experiment, the research staff used a common fruit fly — Drosophila melanogaster, the organism which, because of its cellular mechanisms of development, similar to other animals and humans.
The study research staff used 3 groups of flies. The first group were exposed to daily 12-hour cycles: 12 hours light and 12 hours darkness. The second group was all the time in the dark and was used as a control, a third group was exposed to filtered blue light. According to the study, it was found that flies from the first group had a shorter life span. The study of flies that were exposed to 12 hours of illumination with blue light, confirmed the damage to the retinal cells and even neurons in the brain, reducing the ability of flies to climb the fence.
Were used in the experiment and the mutants are fruit flies, some of which were not developed organs of sight, but even the eyeless flies were revealed brain damage and impaired coordination. Thus, the flies didn’t need to see light to he was able to cause abnormalities in the body. Researchers noted the interesting fact that flies tend to avoid blue light if they are given the choice.

Scientists say that the presence of natural light is essential for the circadian rhythm of an organism — the cycle in which the number of physiological processes such as brain activity, secretion of hormones, cell regeneration, etc. however, increased exposure to artificial light, which increases in the modern world, is one of the risk factor for failure of sleep and many other circadian disorders.

The use of led lighting, different gadgets and devices exposes people to an increasing amount of light in the blue spectrum. But due to the fact that these technologies are fairly new, find out about their impact on the person throughout his life is not possible.
