Fixation and movement are the key to excellent vision
The next technique for natural restoration of vision is called central fixation. This is, perhaps, the most difficult to learn method of removing mental and physical stress, which Bates himself puts in first place in his program. From his words it is clear that the ability to central fixation is of prime importance for normal vision, but from the way Bates describes the ways and means of restoring this fixation, it is so difficult to understand anything, in it. At least I couldn't do it, when I first got it in my hand
For the opportunity to get rid of glasses. I was convinced by Bates's opinion about the causes of visual impairment, his words about the dangers of wearing glasses and the importance of stress relief. However, how only I got to the topic "Central fixation", the enthusiasm to engage my vision completely evaporated. I realized that it is important for eye, but did not understand how to restore this fixation.
The book was abandoned for many years, until I got to a training to get rid of eye glasses, which is stimulated my desire to help people in a similar way, but I also did not understand the essence of the Central Fixation from his lectures. And without this it was pointless start teaching and maintain your visual acuity.
As a result, I myself had to cover myself with books and, having studied various
sources, to finally understand this most important component of our vision.
The central fixation is so hard to understand because it seems that few people really imagine the process visual perception. So let's start with a short description of this
mechanism.
Central fixation secrets
It is known that all rays from a perceived object are focused on the back surface of the eyeball, called retina, or reticular shell. It is the thinnest, most difficult and most physiologically an important part of the eyeball, which is the beginning of the visual analyzer, its peripheral department.
The structure of the eye
Having the most complex structure of ten layers, the retina tissue in the center
becomes thinner to one layer, forming a small depression - the central hole. Inside it is the thinnest layer of the retina and the center of the most acute vision, called a macula. That's what it is central vision, since here is the place of maximum the sensitivity of the eyes, which is responsible for the clarity of the image. Thus, central fixation is the ability of the eyes to see most clearly what we are looking at directly, and not what is around.
Why, in reality, do we not feel this, but see the object either equally clear or equally blurry? Why when looking at a person does not seem to me that I can see his nose more clearly, for example, and less clear - cheeks?
To understand this, it is necessary to remember that the main law of vision is movement, more precisely, the movement of retinal nerve cells at a speed of 100
and more times per second.
