Among modern people, such a problem as visual impairment is quite common. Most often this is due to the development of myopia, age-related farsightedness and cataracts. The latter ailment is increasingly found in residents of the most developed countries. Many who have good eyesight are interested in how a person sees with a vision of -6. In fact, he sees only nearby objects. The farther away an object is, the more smeared it appears.
Vision is adversely affected by many bad habits of people. For example, reading in low light and prolonged work at the computer. If a person notices that his vision is deteriorating, then in most cases he does not turn to a specialist. Many believe that the problem will easily disappear with regular use of glasses or contact lenses. Do not self-medicate, becausemodern medicine has been able to identify a large number of factors that have a direct impact on the ability of vision to focus. Usually this includes not only age-related changes and long work at the monitor. Most patients simply do not know about the reasons that can really provoke a decrease in visual acuity.
Refraction anomaly
First of all, it is necessary to highlight the violations called refractive errors. This includes farsightedness, nearsightedness and astigmatism. The appearance of myopia is associated with lengthening of the optical axis of the eye and a significant increase in the refractive power of the cornea. Farsightedness is, on the contrary, a decrease in the length of the axis. If a person is over 40 years old, then he is at risk of developing age-related vision problems. Around the age of 65, the ability of the eyes to accommodate almost completely disappears.
Spine problems
Another reason that causes vision problems is the pathological condition of the spine. In most cases, we are talking exclusively about the cervical region. If a person gets a neck injury and a displacement of the vertebrae occurs, then such a deformation has a negative effect on the ability to see. This is due to disorders in that part of the spinal cord, where there is a direct connection with the organs of vision. For example, young children often fall and may injure their necks. In the future, this will lead to the development of myopia. As a preventive measure for thiscondition requires contacting a children's hospital. Adult patients undergo a whole range of procedures to completely relax and strengthen the joints.
Loads
Visual acuity worsens with prolonged mental and physical stress. Also, do not write off chronic stress, which negatively affects the functioning of organs and systems. As a result, the body simply wears out. For example, if a person has mental overstrain, then his eyes water and turn red. When such symptoms appear, it is recommended to immediately postpone all business and rest a bit. As a preventive measure, doctors advise to rest more and carefully monitor the diet, because it should contain a large amount of vitamins and other nutrients. To avoid eye strain, there are several exercises you can learn to easily relax and exercise your muscles. Do not forget about herbal compresses and tea lotions.
Infections
Vision worsens with venereal or infectious disease. It has been established that some microorganisms cause damage to the nervous system, so it is not able to fully regulate the work of the visual organ. Certain types of bacteria provoke severe eye diseases, so it is extremely important to seek qualified medical help in a timely manner.
Ecology
Now there is a rather unfavorable situation with the environment, so doctorsthis factor is also attributed to the causes of vision loss. The body gradually accumulates more and more harmful substances, which, over time, adversely affect human he alth. People working in hazardous industries receive a lot of toxic toxins. For preventive purposes, such patients are advised to eat only high-quality foods and regularly take care of the removal of harmful substances. For all systems to function correctly, you should not give up physical activity.
Bad habits
The presence of bad habits is directly related to the loss of visual acuity. Cigarette lovers should be wary of organic changes occurring in the walls of blood vessels. This leads to microcirculation disorders inside the retina. With constant disturbances in blood supply, after a while, a sharp deterioration in vision occurs.
Key Features
If we talk about signs indicating the presence of vision problems, it is important to pay attention to the occurrence of frequent headaches. This suggests that the organ of vision has chronic fatigue.
Poor vision is easy to recognize when traveling in transport is intolerable and you feel dizzy. Also, do not forget about increased excitability and excessive irritability.
The presence of myopia is easily recognized by the habit of bringing objects close to the eyes.
If a person looks at the surrounding objects and notices that all the drawings have displaced proportions, then this is a sure signvisual impairment.
Diagnosis
To maintain eye he alth, it is important to contact specialists in time and diagnose diseases. If we talk about ophthalmology, here the course of the disease and the prognosis are completely dependent on the early detection of pathology. In modern medicine, there are many ways that will help to accurately make a particular diagnosis. Most often, doctors use special equipment, but a number of methods have remained unchanged for several decades.
When presented with a vision of minus 6, the patient is first subjected to a visual examination and verification using an ophthalmic chart. This option does not help to determine minor deviations and the presence of hidden diseases. Experts advise giving preference to a comprehensive check.
Treatment
Laser vision correction is the most effective and harmless way of recovery offered by medical centers to their patients. They will be able to improve their vision and be freed from the continuous wearing of glasses and contact lenses for many years.
The essence of the method is that the "cold" laser beam changes the optics of the eye. This makes it possible to change the refraction of light in the eye - to focus it directly on the retina and, as a result, be able to see an accurate image of the objects around you.
