Besides the baffling light and clouds, the biggest feature of the plateau is the endless green, olivine, black green, dark green and light green which is incredible to the people who have dwelled in the city all the time. For the first-time visitors, the abrupt change from ubiquitous grey in the city to the green all over the plateau makes them pitifully uncomfortable, like falling to the abyss of the green. Some severe sufferers may get temporary lazy eyes. As an art worker, I have the responsibility to inform them the causes of amblyopia, and come up with ideas to help those around me with my professional knowledge. For that reason, I spent a great deal of time on some experimental exercises, trying to find out some ways to adapt the eyes to the plateau. I also carried out a grouped experiment on the people who were about to go to the plateau, and made a follow-up research which proved to be very effective to most people (Several aged visitors who had suffered from eye diseases were greatly satisfied, and brought me pilose antlers and saffron all the way). As a whole, the training program is not perfect yet. But I will timely adjust and improve it according to the feedbacks and suggestions received. Here, I want to share the training program with you for better ideas. I sincerely invite more comments and suggestions so that this program can get perfected and be more effective to all those who practice accordingly.
First of all, it is necessary to know some basic theoretical knowledge before training, it might be boring though, it is important for the succeeding training, therefore, please read it carefully.
1. The physiological features of color vision
In some circumstances, when our eyes are stimulated by light, there are some unique physiological features for the light and color sensory system of our eyes.
1) Light and dark adaptation
When our sense organs get stimulated, the process and the status of change of our sense organ is called adaptation. There are two kinds of receptors with different light sensibility on the retina, so our eyes have the function to adjust the sensitivity by adapting to the light variation in the view. The light and dark adaptation, also known as the ¡°adaptation to luminosity¡±, is a vision perception function of our eyes common in our daily lives. When the vision is abruptly shifted for brightness to darkness, we can see nothing in a brief moment. We may often meet this situation, when we turn off the light in a room at night, we will see nothing but darkness at once. But after a while, we may gradually see the shapes and colors of the objects surrounding us. This is the ¡°dark adaptation¡±. And when the light suddenly turns from darkness to brightness, we will feel dazzled. For instance, when you are sleeping at night, and if you turn on the light of the bedroom, you will see nothing for a short time, then you can identify the shapes and colors of the objects in the room. This process of vision adaptation from darkness to brightness is call ¡°light adaptation¡±.
2) Chromatic adaptation
Under the yellow light of an incandescent bulb, we can only sense yellow color in a short period after the light is turned on, then this yellow color will disappear after a moment. Under this yellow light, the white paper looks still white, and our eyes will adapt to the colors of the objects as under the sunlight. The color vision change caused by the stimulation by the environmental color is the adaptation of our eyes to the color light, and it is called ¡°chromatic adaptation¡±. The first sensing period usually lasts about 5 to 10 seconds, after which the ¡°chromatic adaptation¡± takes effect. The instinct to habitually restore the colors of the objects to the original ones under sunlight is directly related to ¡°Color constancy¡±, or to the concept of ¡°intrinsic color¡±. These two concepts prevent our eyes from being cheated by the object color caused by the color of the light source, and enable them to get the true attributes of the object color. The adaptation ability of our eyes to color is of great importance in our daily lives.
2. Eye training for adapting to the green color is quite necessary in order to prevent green blindness
To categorize them in more detail, the green colors can be further divided into vivid green, yellow green, willow green, blue green, union yellow, light green, union green, blue green, fresh green, glossy dark green, dark green, viridity, verdure, emerald, grass green, jade green, green-white, black green¡For beginners, they can advance gradually in due order, from the simple to the complex, from perception to rationality, so as to adapt their eyes to the profound green system gradually. Green is the mixture of yellow and blue. In the green the sense of expansion of the yellow is neutralized with the sense of contraction of the blue, the warmth of the yellow counteracts the coldness of the blue, thus making the green mild and placid. Green is a soft, peaceful, satisfying and graceful color. When the element of yellow dominates the green, then the green tends to be brisk, friendly and naïve. If minor black color is added to the green, then the character of the color will be stately, seasoned and mature. And if a trace of white, then the green will become clean, clear and fresh. The trainees can tend to the influence of the color to the mind during the practicing process, at the same time practice their ability to control their sensibility of feelings (such as love, romance, passion, fervor, softness, elegance, vigor, nature, freshness, sobriety, desolation, serenity, depression, gloom and mystery etc.)
1£© For beginners, it should not be too strict. They can randomly choose several favorite colors for a simple practice (there is no requirement for the materials, they can paint whatever they like, and the canvas doesn¡¯t need to be neat. They can also play some relaxing music while painting, so as to train them how to identify different types of green in a totally relaxing status).
2) With the increase of their knowledge, they can try to make changes, so as to experience the vision and psychological change with the change of green. For instance:
practice to add white to various types of green. Increase the adding times with the same quantity of white ach time, then make the green become lighter and lighter (feeling fresh and clean);
practice to add black to various types of green. Increase the adding times with the same quantity of black each time, then make the green become darker and darker (feeling serious and seasoned);
practice to add yellow to various types of green. Increase the adding times with the same quantity of yellow each time, then make the green become warmer and warmer (feeling lively and friendly);
(Note: this period should be limited to around 15 days, and at least 5 hours per day).
3) When they reach a certain degree, they can practice the complicated graphic change, making inclined colors and rich emotions freely change in the illusions, so that the practicers will come to a new height either in their observation of green, or in the control of their emotions (For instance, when the high-purity green is juxtaposed to the low-purity green, they can feel that the high-purity green is much more brighter, while the low-purity green is much more dimmer; when they are trained with cold green and warm green, the cold green will make them feel depressed and indifferent, while the warm one makes active with passion; and when highly bright green is juxtaposed to the low bright green, they can feel that the bright green becomes brighter, while the low bright green is more darker). We can provide some ready sample pictures, e.g. we can randomly take several pictures form the works of artist Victor Vasarely as templates for the beginners to practice.
Note: After over 3 hours of consecutive practice, older aged trainees will have a transitory vision effect of negative after-image, i.e. all the objects are in red color. Then after a while of rest, the vision will become normal. (negative after-image is the afterimage of the nerve excitement, and caused by the continued stimulation of objects to the eyes, so it is also known as ¡°successive contrast¡± visual illusion. The phenomenon of negative after-image means that our vision still remains to the mixture of the object color and light color for a brief time after continued stimulation by the object color and light color.)
