Photobiologists warn: LED lights are harmful to health

Millions of years of evolution the human's eyes of many Europeans become blue in color. In this way, nature took care of the eyes' health. In winter days, when the Sun shines it reflects from the snow, giving a blue specter, which harms to eyes and to the health. Blue eyes absorb other parts of the spectrum and reflect blue light. It explains, why other people like Chinese or African don't have blue eyes: they always live in the southern climate.

Also from our experience, we know how harmful the light from welding can be for eyes. So it is undoubted, that the best light for human beings and domestic animals is the sunlight, which has a warm yellow and red color. In the old times, when people went to bed at early night and woke up with a dawn they use only light from fire such candles or oil lamps and their eyes have not been adversely affected. Nowadays a lot of people spend time reading books, watching TV or surfing the internet, exposing their eyes to a significant stress. Together with this, we switch on light almost everywhere thus we further impair our eyesight, especially with modern luminescent or energy-saving lamps operating in the blue spectrum. 

This research shows that is especially harmful to people living in northern countries such as Russia, Norvey of Finland. In a half part of Russia up to six months there is no sunlight and severe cold. So most of the day people lives with an artificial light. Thus one year of life beyond the Arctic Circle can be counted for two. Some families after they retired go to southern regions and die in 10 years. It confirms that light plays a huge role in health and longevity.
