Foreign researchers give the alarm that the number of people affected by myopia is increasing across the globe. If you find it difficult to see distance objects, this is a sign of myopia. But do not worry because you are not alone.
The number of myopies in the world is growing. A new study shows that the number of myopia is increasing, not only in America, but across the globe. This has made scientists ask, why?
First of all, this shows that the optometrist profession is prospective. The study shows that more and more Americans need lenses to improve their viewing.
People with myopia can better differentiate objects when they approach them close to the eyes, while away they look faint or dark.
An analysis by the National Institute of Disease Syndrome shows that over the past 3 years the number of cases of myopia has increased considerably. The latest data shows that 42 percent of Americans between the ages of 12 and 54 are myopia, compared to 25 percent in the early 1970s. But in this regard, Americans are not alone.
According to the study published in the Archives of Ophthalmology, similar trends also show studies from Asia, Australia and Europe. The question arises, why this sudden increase in myopia cases? Scientists have many and varied theories. Some say that a gene that is responsible for first-person organs may have undergone any changes or mutations that cause myopia.
Others blame the spread of computer technology, which makes people stay prolonged hours with embedded eyes on the computer screen. Fortunately, myopia is a problem that is easily corrected with glasses, contact lenses, and laser beam operations. But the financial cost should not be forgotten. According to estimates, the increase in myopia cases has increased total medical costs by $ 3 billion.
As a result of the development of contemporary technology with very rapid leaps, in recent years myopia in children of small and medium age has largely increased. The child’s viewing system is in permanent development, and therefore adverse environmental factors can affect this system negatively, which partially affects the development of myopia in children. Overcrowding also plays a major role in the development of the viewing system.
These overloads include drawing, reading (near-zoom overhangs), as well as watching TV. What happens to the child’s viewing system when he is watching television for a long time? The image from the TV screen is projected into the retina (at the end of the eye). But in most cases, children of small ages are hyperthermometric, so that the child can clearly see the image from a certain distance, it must strain certain eye structures.
This happens in a reflective way and does not depend on the child’s awareness. When muscles arise, we see small and mobile figures, this is often the case when we look at the television, not excluding the disorder of the compensation system and the introduction of myopic mechanisms (eye opener). As a result, this may develop myopia in children. Myopia is one of the most prevalent diseases in children who have gone to school. At age 14-15, virtually almost every child suffers from myopia. This is because the eyeball is prolonged, so the light does not focus where it is needed and the child complains that he does not look good. In order to look good objects that are far away from the children gather their eyes, the eyelids so collected play the role of the diaphragm and as a result the image in the retina becomes clearer.
The treatment of myopia is complex, directed in all aspects that progress it. Generally, myopia is treated conservatively, including various functional methods. These include exercises on certain devices, physical methods of treatment and medication methods. As a rule, when myopia is treated, doctors give goggles. For the lower and middle class myopia, glasses are recommended for far away, whereas for the high-grade myopia are given goggles for persistent retention.
Although glasses themselves do not have any medical effects, they are just a remedy when treating myopia in children. Medical effects have only contact lenses. The maximum effect is achieved only when strong lenses are held, but also when the patient is wearing soft contact lenses. When the myopia progresses rapidly (more than 1 diopter per year), or when there are end-eye complications, surgical intervention (scleroplasty) is performed as a complementary stage of myopia treatment. According to some doctors, it is not worth the overestimation of scleroplasty opportunities. Unfortunately this operation does not provide 100% guarantee that myopia will not progress even after it. Operation is not an alternative to conservative treatment
