The principle of myopia neutron scope
The myopia neutron scope is based on the teachings of Xu Guangdi, an optometry expert, leader of the Youth Myopia Prevention and Control Group of the Ministry of Education of China, and an authoritative figure in the field of optometry.
The principle of prism plus convex lens proposed by the professor was developed and is currently the most effective principle for preventing and treating myopia in teenagers. When a convex lens replaces the eyes for near vision, the lordosis of the lens becomes thicker, prompting the ciliary muscle to relax and reversely regulate the lens.
The principle of prism refraction is used to reduce the convergence (convergence) of the eyes when looking close, thereby achieving the purpose and effect of controlling the development of true myopia and alleviating pseudomyopia. Its unique feature is that it can not only see far like ordinary glasses, but also achieve the purpose of physical therapy. At the same time, it can also make users comfortable and less fatigued when reading.
How to use
1. The lens glazing area is used for distance vision, walking, reading the blackboard, watching TV, going up and down stairs, etc.
2. The lower light area is used for reading, writing and overlooking (relaxation, adjustment and gathering).
(1) When reading and writing, use the lower light area to find a clear position for reading and writing from far to near.
(2) The position where you can see clearly is slightly backward to reduce blur, and the position where you can read (or write) is the best treatment position. (Tell students to look for slightly blurry positions in succession)
