Place your finger or pencil vertically in front of your eyes. Alternately closing the left or right eye, observe how the position of the finger changes against the background of objects located behind it. Describe and explain your observations
The eyes see the same object from slightly different angles, but this difference is not noticeable to a healthy person. The brain processes the signals sent by the organs of vision, and forms one accurate image from two pictures.
You can make sure that each eye has its own angle of view by closing one eye and looking at your finger relative to the background. Then, by closing the other eye, you can see that the paleae “shifted” relative to the objects in the background.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
