For a person, vision is the main source of information about the world. The share of this information is about 90%. The eye is often compared to a camera. It would be more appropriate to compare it with a television camera mounted on a tripod, with an automatic tracking system – a machine that self-focuses, automatically adjusts to the light intensity, has a self-cleaning lens and is connected to a computer with such advanced parallel processing capabilities that engineers are just beginning discuss similar strategies for the equipment they are designing. The gigantic work of transforming the light falling on two retinas into a meaningful visual scene is often strangely ignored, as if everything we need to see is an image of the outside world, clearly focused on the retina. Although getting sharp images is an important task, it is modest compared to the work of the nervous system – the retina and brain. No human invention, including computer-controlled cameras, can yet compete with the eye.
Why 
not concentrate on saving it now?
First of all, limit the time of your stay on the screens of gadgets. For example, allow yourself to use the phone only an hour a day. In addition, smartphone users should install a screen that protects their eyes from blue light on their phones.
If you work at a computer – try to work, being at a distance of 60 cm from the screen. And of course, take breaks in work.
In the struggle to preserve vision, eye exercises will help you. You can do them in the morning, in the evening, and in the afternoon.
Correct reading, Nutrition too, must be the main parts in maintaining vision.
In addition to protecting your eyes from harmful influences, you need to know how to preserve function with the help of the right food. Your eyes should receive all the necessary vitamins, antioxidants and nutrients, because their work depends largely on what we eat.
