One should not categorically declare that television is harm. Psychologists and doctors have conducted studies, on the basis of which it is worth concluding that the choice of viewing programs must be taken very seriously. Many of the stories that are broadcast on television are very interesting and informative, not to mention the daily news. However, one should not forget about the harm to health.
Visual disturbances
The contact with the retina of the image of the object under consideration is organized by the accommodative apparatus of the eye. It should be noted that with myopia, such light rays, after natural refraction, are focused, not reaching the retina. Thus, distance visual acuity is greatly reduced. Myopia is a condition in which a person sees well objects that are near, and poorly - distant from him. The causes of myopia are varied and many.
Also, the visual perception of television programs is the rapid discrimination of a huge number of small details. At this time, the eyes have to do a tremendous job, which is associated with the need to move the eyes across the screen and examine the text. This is fraught with great strain on the eyes. It should be borne in mind that the eyes during this period move in a kind of uneven jumps. This feature leads to eye fatigue: a feeling of cramps appears, the eyelids turn red, the muscles of the back and neck get tired.
The benefits and harms of television
Television is not in vain considered one of the most significant inventions of mankind. Since the time that television has firmly entered our lives, a lot of both good and bad have been expressed in its address. Be that as it may, regular TV viewing, like any visual work, can lead to great fatigue. Eye strain is not due to some special specificity of television programs, but rather to the fact that the systematic viewing of television turns into a large additional burden on the eyes. If you visit cinemas, concerts, museums or theaters, it is generally not recommended to watch TV programs on the same day. Such an overload of impressions will not only adversely affect the eyes, but also affect the nervous system: anxious sleep, irritability and increased excitability will appear.
Experts give the following recommendations when watching television programs, adhering to which you can avoid health problems:
1. It is necessary to sit at such a distance from the TV screen that it is convenient for your state of vision.
2. Do not tilt your head forward while watching TV. The head should be straight.
3. Breathe deeply and blink frequently. Remember: in tense moments of various actions on the screen, a person often holds his breath, which is unacceptable.
4. Instead of staring at one point, the eyes should move across the entire screen.
5. During long scenes, cover your eyes a little, giving them a short rest. At this point, the muscles relax.
