Neutron mirror is developed according to the principle of prism convex lens put forward by Professor Xu Guangdi, an optometrist, the leader of the prevention and treatment group for juvenile myopia of China Ministry of Education and an authoritative figure in optometry. It is the most effective principle to prevent and treat juvenile myopia at present. When the convex lens looks near instead of the eyes, the convex lens becomes thicker, which promotes the lens at the ciliary muscle to relax the state of reverse adjustment. By using the principle of prism refraction, the convergence of eyes is reduced when the eyes are close, so as to control the development of true myopia and relieve pseudomyopia. It is unique in that it can not only see far like ordinary glasses, but also achieve the purpose of physical therapy, and at the same time make users comfortable and not tired when reading.
Application mode
1, the lens polishing area is used to look far, walk, watch the blackboard, watch TV, go upstairs and downstairs, etc.
2. The lower lighting area is used for reading and writing, and for overlooking (relaxing and gathering).
(1) When reading and writing, use the lower illumination area to find a clear reading and writing position from far and near.
(2) The position where you can see clearly is slightly behind to reduce ambiguity, and the position where you can see (or write) is the best treatment position.
