Events of the day – Experts said that making children play abroad is beneficial to their eyesight as it reduces their risk of sight loss.
A short look becomes common throughout the world, and by 2050, this visual disorder will affect some 4.8 billion people, and hit 2.8 billion people worldwide in 2010.
Although many tend to blame their genes for this problem, genetics can not just explain this rapidly developing problem.
Much of research suggests that outdoor play can reduce the risk that a child expects.
Outdoor presence does not only force you to look further, but it is also believed that exposure to external lighting is essential, as it seems to slow down the central growth of the eye, as excessive growth contributes to myopia.
One study found that if the child did not spend enough time outdoors, when parents had a lack of sight, the genetic risk increased to around 60 per cent.
In light of these developments, experts now believe that the environment plays a bigger role in myopia than genes.
A study of the twins of 1991, born between 1994 and 1996 in the United Kingdom, followed the data of the study of early development in twins.
During the first 16 years of life, experts developed the development, behavior and education of each child through questionnaires and tests, as well as collecting eye tests.
Interestingly, the study identified four major environmental factors associated with lack of understanding, some of which were unexpected.
The study found that children born after the mother receiving fertility treatment were 25 to 30 percent less likely to develop a short look at middle age.
"This may be partly related to the fact that babies born after fertility treatment tend to have lesser birth weight and shorter pregnancy and, according to some studies, not all of them have deferred development and reduce cognitive scores, "said experts. A reduction in cognitive grades seems to reduce myopia.
The study also found that those born during the summer were more likely to be flawed, probably because they started going to school less than many peers .
The study found that the mother's education level was higher, higher than the number of teenage sight loss by 33%.
This could be associated with the connection between intelligence and short vision, although social factors such as class and wealth can also play a part.
Certainly, technology is responsible for the causes of sightlessness, but for a different reason than what is believed. The main reason why technology in the cause of myopia is not directly harmful to the eye (it is damaging), but because it uses children's time that can be allocated For fun and moving abroad.
Experts say: "The increase in the time of watching the screens of electronic devices derived from the use of games and social networks and digital entertainment has led to an increase stable behavior, and lack of nutrition and lack of outdoor activity. "
But experts say that these environmental factors are only associated with myopia. Of course, they do not necessarily cause a shortfall.
But another part of the study may be worse. The study was carried out on children born in the 1990s, before the smartphone and other handsets.
At present, with the eye attached to the screen regardless of what we are, even if it's outdoors, it's likely that the problem will be much worse.
