If in childhood you read a lot and sit at the computer, then it often happens that from a simple understandable "nerd" you turn into the most ordinary "spectacle". To your parents, your preferences may seem harmful to the eyes, then you sit on the seashore and look into the distance, at the horizon line, where the sky and the sea touch, where there is nothing that would touch your eyes. For a long time, nothing happens there, a line and a line, not imaginary, but a completely visible border between the sky and the sea. Some time passes and you suddenly begin to see some ships, boats, stones sticking out of the water or birds flying, there at the line. You turn around and ask those who are next to you,
"Are there any ships there?" Out there almost at the horizon?
It turns out that there is, it turns out, you really see, although you are not sure that the ships are not a figment of your imagination, because a few minutes ago at the border of the sky and the sea you did not see anything.
For yogis, the sea may be far away, not everyone can sit and watch the air and water come together. Yogis find it useful for the eyes to look at nature and the starry sky. Poetically, they talk about the blue flow of cosmic energy, penetrating into you and protecting the eyes, normalizing vision, and at the same time other body systems.
Yogis may wear glasses, but much less often than the mental and office workers who surround us in everyday life. How do they do it?
They just love to take care of their body, their eyesight in particular. No matter how stressful their daily routine is, they find time for "palming". Simple actions give a pronounced and very pleasant effect, even the headache passes.
To begin with, warm up the palms so that they become warm, kind and soft. You can separate them at a distance of 10 centimeters and feel the heat. The palms are folded one on top of the other and laid on the face, closing the eyes, and the palms intersect somewhere just in the place where more advanced yogis find the third eye.
If you have already closed your eyes and are ready to relax, open and check if the light penetrates through your fingers or from the side. Move your palms so that you don't see the light. Now you can close your eyes and relax. You will see a gray or black background, perhaps there will be lines, dots, faces on it, relax, remove all foreign objects and images, bring the background to a completely black color. You may need a few minutes, perhaps several attempts. Black color is an indicator of restless and healthy eyes.
Only after your palms have given your eyes the opportunity to rest, you can proceed to a set of exercises for the eyes.
Interestingly, palming is advised by almost all doctors and schools that use sets of exercises for the eyes. If somehow you can devote an entire day to palming, don't worry, there won't be an overdose.
Almost all eye exercises include training the eye muscles, which, in addition to improving vision, protects the face from swollen eyes. The eyes make movements up and down, right and left, it is necessary to fix the eye in the extreme position. Exercises can be done with both open and closed eyes. Yoga muscle training for the eyes involves slower movements based on imaginary vision. Yogis draw a circle with their eyes, turning their eyes counterclockwise, very slowly, trying to ensure that one circle takes a minute, the eyes are also fixed at the extreme positions of the circle, in the direction of the corners of the square, in which you can inscribe the imaginary circle drawn by the eyes. Strive to ensure that each time the circle becomes larger and larger.
The circle is not the only figure that the yogi draws with his eyes, triangles and squares, any figures and lines will do, but the general principles of the exercise are preserved: slow movement, fixation in extreme positions, expansion of the coverage area.
Myopia and farsightedness are the most famous visual impairments. People who are short-sighted "read with their noses", farsighted people move the book sometimes to the full length of the arm, away from the eyes. Classic sets of exercises for the eyes include this:
Go to the window and put a dot on the glass, where there is something outside the window that you are pleased to look at. Shift your gaze from a point on the glass to the object you choose on the street and back again.
Yogis offer to sit on a mat with a straight back, the posture for yogis is important, the flow of energy inside the body depends on it. There are no special breathing requirements in this exercise. The gaze is directed at one point directly in front of you. On exhalation (through the nose), without changing the position of the head, you need to turn your gaze to the upper left corner and hold it there until you want to blink. Then inhale, exhale with your nose and both eyes look into the upper right corner until you want to blink. 
Inhale and exhale again through the nose. The gaze is transferred to the finger, prudently placed on the line of the nose. From the finger, the gaze passes directly to the tip of the nose. From the tip of the nose to the finger, located on the bridge of the nose line, the next movement of the gaze to the between the eyebrows. The exercise is performed slowly, each of the points of attraction of the gaze is fixed, in each breath it is accompanied by a discharge of air through the nose.
Although the exercise seems abstruse, as a rule, recommendations were collected for generations based on observations of the state of the body and their own sensations. Before laughing at the formula "on the object – on the nose – on the object" proposed by Bogdanova-Chesnokova in the film "Cinderella", why not try the formula of yogis "right – left – right – in front of the nose – on the nose – up to the bridge of the nose – between the eyebrows"? Perhaps your eyes will like it more than your stepmother's daughters.
