Nature - Every computer technician has had to defend himself against allegations that several hours every day in buljenje monitors corrupts eyes. Poor quality images, which are all modern displays virtually eliminated, lousy lighting, fixed focal length, eye fatigue and lack of squinting are just some of the factors that people vien rang ham mat cite as reasons for the deterioration of vision. At first glance, secures vien rang ham mat them a reality, because the incidence of myopia in the developed world is steadily growing. A survey vien rang ham mat suggests more complex picture. The subject line can be drawn that they had grandfather right when they said to go juveniles out on the air, we read in the latest issue of Nature. In amblyopia busting Asians. 90 percent of Chinese people is myopic, the South Korean capital, this percentage was even higher among young people. In the US and Europe is myopic about half of young adults globally this share is about 30 percent. One hundred years ago it was much smaller. What happened? First of all, let us say, what is myopia. To see sharply, the lens is broken so light that collects on a flat retina. If the lens refracts light too strong and it is collected prior to the retina, and then to her already somewhat dispersed, talking about the short-sightedness. Sightedness is the opposite problem when the lens is too inflexible and fails to sufficiently break light, it would be gathered in this section of the retina. In both cases, the result is the same - to see foggy, but once seen lying nearby objects, other times more distant. While the foresight age nuisance, vien rang ham mat the myopia most often occurs during puberty or adolescence, vien rang ham mat when the eye grows. Therefore, the statistics are talking about young adults - five toddlers usually but not short-sighted. Short-sightedness and far-sightedness, of course, to some extent, genetic conditions, such as congenital defects, all in the human body, but this can not be the main reason. Already in 1969, studied vien rang ham mat myopia in Inuit, and found that its incidence in isolated vien rang ham mat communities of less than two per cent. As many as half the grandchildren of these people was myopic, which is strong evidence that the reason lies in the environment. It has to be just find. Thought would be that the reason for the long hours that modern young people spend in front of books and computer screens. Sounds logical, since the short-sightedness of the most prevalent also in East Asia, where the maximum load of school. The average Chinese in Shanghai has 14 hours of homework per week in Europe and the US half. The problem was considered solved, vien rang ham mat as well as further research confirming vien rang ham mat that more reading books raises the risk of developing myopia. The explanation is elegant and logical, because long-term focus close image affects the growth and development of the eye lens. Unfortunately, it also explains wrong. Only at the turn of the millennium, new research has shown that it is another reason. Myopia develops in the absence of spending time outdoors. Since the book is usually read in a confined space such studies have not
