Centralization is seeing best where you are looking. This may seem simple at first but can ultimately prove to be more complex. Centralization is due to the anatomy of the eye. All along the back side of the inside of the eye is the Retina, which contains visual pigments called Rods and Cones. Rods give us the ability to see in night and comprise our peripheral vision. Cones are activated in the daytime or in bright light and let us see sharp details and colors. The dispersion of the rods and cones is very important. The rods are dispersed all over the back of the retina except for the very center, which is called the Macula. In the Macula is a pit called the Fovea Centralis. In this pit is where all the cones are located. This is our center of sight, the point where the light is meant to focus as it enters the eye. What this means is that the clearest point of our field of vision (what we see) should be the one point we are looking at. Everything in the periphery, everything around what we are looking at, will not be as clear as that which we are looking at. Any attempt to bring everything in the entire visual field into focus results in strain, and therefore decreased vision.
To practice centralization, gaze at the diagram of the Tibetan Wheel. Start at the top circle and notice how it is clearer, blacker and more distinct than all the other circles. Work your way around, keeping your attention and focus on whatever point you are looking at. Once you get the idea on the outside, start to make your way further in toward the center. Eventually you will end in the very center at the tiny black dot. Close your eyes and imagine this tiny black dot. This can represent your Fovea Centralis, your center of sight. Take this dot with you after you leave this website into your daily life. Imagine a tiny black dot everywhere you look and use it to trace around objects and people. Stop trying to see everything clearly at once and start seeing everything in small parts that make up one clear whole. Centralization will help reawaken the Fovea Centralis and help restore the eye to its normal rapid speed of 60 to 70 vibrations per second. The eyes want to move!
