Optimal Design And Study Of Sitting Posture Orthotic Device To Prevent Myopia In Primary School Students

For the past few years,The number of myopia patients has been constantly increasing in China.A high incidence of myopia and in adolescence is developing fast,the effective treatment of myopia is difficult difficult,sick for teenagers has a great influence on learning and work,has drawn the attention of the society from all walks of life now,more and more researchers suggest that the onset factors lead to the poor posture in reading too close to one of the main factors.In the school,family environment,the occurrence of children near learning is very much.At present,there are many products aimed at preventing proximity learning behavior in the market,and their use methods and effects are also quite different.However,there are few comparative studies on the effect of use.Aiming at the problem of near learning,this study will carry out a comparative test on the effect of product design for prevention of near learning,and design according to the results.Research methods mainly through literature review,field testing,methods of market research,to understand user base,analyzed its demand,and through on-the-spot investigation to collect the user data,using SPSS for data analysis,the results showed that higher relative height,horizontal distance closer to keep a book under the condition of the eye distance distance is relatively far,study on product design to the conclusion.The design ideas and principles of children’s anti-myopia products are discussed.The design theory is used to optimize the readily available products,suppling design ideas for similar myopia prevention products.
