The myopia It is a common state of the vision in which Evil objects are clear, but distant objects look blurry. Myopia It is a medical term. It occurs when the shape of the eye, or the shape of certain parts of the eye, the light rays deviate or break. The light rays that must concentrate on nerve tissues from the back of the eye, or the retina, focus for the retina.
Myopia usually appears during childhood and adolescence. In general, it is stabilized between 20 and 40 years. It is usually inherited. A basic eye examination can confirm myopia. You can correct the blurry view with glasses, lenses or refractory surgery.
Every year the number of people with myopiaA state of the position that produces blurry view of distant objects And the case studies is diverse. From the World Health OrganisationThey calculate that In 2050 half the population of the planet He will suffer.
A combination of genetic, environmental factors, habits and lifestyle
Experts agree that the increase is due to a combination of Genetic, environmental factors, customs and lifestyleSo the role of using screens in the development of myopia is subject to research of the National University of Seoul in South Korea.
Cristina Álvarez, member of the Optometry and Vision of the Complutense University of Madrid, UCM departmentnoted in Rne mornings, This cannot specify whether the specific data of the study is completely accurate. The researcher works together in one of the studies of the Complutense University of Madrid who, among other things, analyzes that of Seoul.
«They are studies in which no We measure Time objective data, but are Questionnaires that we do with parentsSo […] You have to take them carefully They provide us with information that the use of screens increases the risk of myopiaBut to give exactly 21% every hour, I would not dare to give it.
Until now there were no convincing studies that quantify the degree of affection that could cause user fans, tablets or computers; But the South Korean study that reveals Continued use of screens for more than an hour a dayit would increase The risk of developing myopia up to 21%. This percentage would be greater, depending on the number of exposure hours.
Childhood is an important period for eye health
Researchers have analyzed various studies from all over the world, compiled the records of more than 300,000 people and the closure of the sample between two -year -old and young children. Most important years for the growth and development of the eyeball.
The size and shape of the eye depends on the point at which the image forms in the retina. Ideally, it is formed in the middle of it, but in a person with myopia That image forms just before her and for that reason The blurry vision appears in distant objects.
Can the development of myopia prevent childhood?
One of the conditions that affect development on myopiaIt is the Excess time tasks to see closely how the screens should see the screensHow to read, write or clearly, screens wears. When children grow up, the key is to develop in the most correct way, their eyeball is possible, that’s it Seeing the alternation between closely and far, with daylight.
“Various environmental factors have been investigated […] And the one who affects everyone most is, is Take the time outdoors“, The researcher explains and adds:”If children spend more than two hours outdoors every day, the risk of myopia is drastically reduced and that is the factor that has the most influences“
Cristina Álvarez concludes that “The solution is therefore“
