Why does myopia occur?
Visual impairment such as myopia is quite common. Myopia or myopia may be caused by a hereditary factor, or it may develop due to constant overextension of the eye muscles (false myopia). Is it possible to prevent the development of myopia? Let’s figure it out.
What is myopia: how does the vision change with myopia
Myopia is a type of visual impairment in which parallel rays from distant objects located in front of the eye retina. Loosening accommodation – the restructuring of the focus of the eye when looking at objects that are removed to different states can be many factors. The weakness of the ocular sclera leads to progressive stretching of the eyeball, which leads to changes in the retina and choroidal membrane. Contribute to the weakening of accommodation and stretching of the sclera common infections and intoxication of the body, disorders in the endocrine system, metabolism, etc.
Myopia is manifested by a decrease in visual acuity, especially when looking at distant objects. Work at close range, reading books, etc. may be accompanied by pain in the eyes, temples and forehead with myopia. Often, myopia develops in younger schoolchildren, and by the age of 20 the disease progresses.
Factors contributing to the development of myopia
Ophthalmologists have noted that a number of physiological factors are transmitted from parents to a child, not as such, but poor vision. This may be the size of the eyeball itself, the properties of the lens to refract light. For example, the elongated shape of the eyeball tends to stretch the posterior wall of the eye, which can later lead to changes in the fundus of the eye. If both parents are sick with myopia, then the probability of the development of myopia in a child is about 30%. Also to myopia can lead to:
Problems with the musculoskeletal system: flat feet, scoliosis, etc.
Infectious diseases and allergic conditions
Birth injuries, brain injuries
Chronic diseases of ENT organs: adenoids, antritis, etc.
Weakening of the body’s defenses
Excessive eye strain: prolonged work with gadgets, poor lighting of the workplace, reading in transport and lying down, etc.
Treatment and prevention of myopia and other visual impairment
Uncomplicated myopia is well corrected with glasses. In addition to vision correction, the ophthalmologist will recommend a special gymnastics for the eyes, adherence to the work and rest regime, possibly with the progression of the condition also medical treatment. It is important to correct false myopia in a timely manner. The workplace or place of study should be well lit, it is also important to observe the correct fit when working at the table – writing, reading.
To maintain visual acuity is important overall strengthening of the body. You should also limit the work at a close distance, after 30-40 minutes of work, take breaks and remove tension from the eyes. Good nutrition, sleep patterns, rest, timely treatment of infections also occupy an important role in the prevention of eye diseases.
