One day, a person notices that the world has dimmed, objects have become fuzzy, faces are blurry, and reading books is tiring and leads to a headache.. Often at first people do not immediately realize what happened, and they blame age, stress, depression.. All this is possible, but most often these symptoms are explained by the fact that vision began to deteriorate.. As a rule, we rarely notice it right away, usually already when the process has gone far enough.. And the first thing a person rushes to do, finally realizing that vision is deteriorating, is to buy glasses or contact lenses..

In fact, it is desirable to first find out the causes of visual impairment, and eliminate them.. After all, if the process has not yet gone too deep, it may not be too late to return the lost, but even if the changes that have occurred are irreversible, it will be possible to stop the progression of the pathology, or at least slow down the process..

One of the most common causes of visual impairment is paperwork or computer work.. The point here is not in the computer as such, and not in the papers, but in the fact that the eye muscles are regularly subjected to excessive and at the same time monotonous load.. These muscles are responsible for adapting the eye to a changing focus of vision, and if the focus is not changed for a long time, then they weaken and become flabby.. The person notices that now he needs to constantly make some effort to keep the picture, all the time striving to blur.. For prevention, it is necessary to do exercises every half hour of such work to change the focus: look at a distant object, then at a near one, then again at a distant one, and so on.. , within minutes.

Poor circulation. Visual impairment may be due to the fact that the eyes simply do not receive enough nutrition.. The reason is usually banal - osteochondrosis, which affects more than 90% of citizens aged 40 years and older.. In this case, everything that is aimed at combating osteochondrosis of the cervical spine will help, mainly these are special physical exercises and massage techniques.. Osteochondrosis is a disease associated with a sedentary lifestyle, and if you add it to your daily schedule of physical activity, then it can be completely avoided, and therefore visual impairment.

Improper nutrition. In order for the light-sensitive pigment responsible for vision to be produced, it is necessary to receive a sufficient amount of provitamin A, or vitamin A itself.. to prevent a deficiency of these substances, you need to eat fresh carrots, blueberries, fish, cod or beef liver, eggs, milk. Carrots are the most accessible for daily consumption, however, it should be noted that vitamin A is fat-soluble, which means that fat is needed for its absorption.. Therefore, to prevent visual impairment, it is better not to eat carrots in their pure form, but fresh carrot salads seasoned with oil or fatty sour cream.
