1. Integrate the functions of myopia prevention, memory enhancement and eye protection with homework. Let students get the care of myopia prevention and eye protection in completing homework at home; get the care of myopia prevention and eye protection in the image type super memory training. In the writing board of the lamp to complete homework (reading, writing), due to the limitation of the eye book distance, and defocused mirror will be reading, writing virtual look into the distant landscape, so that the eyes in the completion of a large number of homework, always in the active rest state without regulation, collection. It can effectively prevent the development of myopia and visual fatigue. The lamp provides a more systematic basic and hands-on training of graphic supermemory and an improved memory test method. The graphical supramemory training process is almost always done on the desk lamp writing board, which is influenced by the active relaxation adjustment of the limiting distance and defocusing mirror. Therefore, it plays the role of myopia prevention and eye protection during the whole process of memory enhancement. 2, this lamp is also the first image type ultra-memory training device in China, has obtained a number of national patents and intellectual property protection. In the supermemory training has the following characteristics: 1, it collects the main methods of contemporary image supermemory training (intuitive image method, visual perceptual learning method, imagination – hanging ditch method, etc.), and innovative solution to the memory training book can not provide visual perceptual learning experience of the real problem. 2, the lamp memory training program focuses on solving the problem of naturally transforming memory information into graphic information and storing it in the right brain functional area to produce long term memory. 3.The lamp provides more than 20 kinds of experience and training scenes necessary for visual perceptual learning, which provides the necessary conditions for rapidly establishing right brain photographic super memory. 4.The memory training program on the lamp starts from mobilizing the excitability of the right brain a-wave and eye-brain sensitive areas, gradually deriving the outline of intuitive images, and then stimulating the eye-brain sensitive areas with flat and three-dimensional methods, so that they gradually reflect the intuitive images.
