Prevention of visual impairment among adolescents.

Eyes can be called one of the most precious human organs, because it is the sight that allows you to see, write, read, draw, perceive the world around you!

The period of the visual organ functional instability coincides with the school starting age – 6-7 years; about 4-5% of children already have vision problems even before they start attending school. Visual workload constantly increases with the grade progression, and as a result, the number of adolescents with visual impairment increases. Therefore, prevention is very important for schoolchildren.

Prevention of visual impairment is a package of simple measures that will help maintain healthy eyesight for many years.

  1. Reasonable visual load. Like any human organ, the eyes get tired and reduce the efficiency of their work due to excessive efforts and strain.
  2. It is necessary to limit TV viewing, computer use, and most importantly, the use of modern gadgets (in particular mobile phones). The closer the distance, the greater the load on the eye muscles, and the more often eyes need a break and rest.
  3. Reading and writing: a) lighting should be preferably natural, if impossible, good artificial; b) monitor the child's posture while reading and writing – an straight spine and the distance to the notebook (textbook) should be no less than the length of the teen's forearm; c) exclude reading while lying down.
  4. If the child does not sit in the middle row at the classroom, it is imperative to change his seating so that the eyes do not get used to looking at the blackboard at the same angle.
  5. Fresh air and physical activity are also important. The whole organism in general and the visual organ in particular needs daily morning gymnastics, being out in the fresh air for 1,5 – 2,0 hours.
  6. Healthy eating during adolescence is essential to prevent visual impairment. First of all, a child's diet should include foods containing vitamin A (retinol): carrots, melons, broccoli, peaches, etc. The fat-soluble vitamin absorption in parallel with these products needs getting fats of various origin. Retinol is also found in fat-containing foods such as milk, eggs, fish oil, cod liver and others.
  7. Lutein and its isomer zeaxanthin are two carotenoid pigments that are essential for the normal functioning of the visual organ. Our body cannot synthesize them on its own. There are not many foods containing carotenoids (persimmons, spinach, black grapes, sweet corn, orange peppers). It is useful to drink vitamin complexes for children containing lutein and zeaxanthin 1-2 times a year.
  8. It is necessary to undergo an annual examination by an ophthalmologist for the timely diagnosis of initial disorders, when there is still a chance for full restoration of vision, and timely and adequate correction in case of an already formed pathology.
