Abstract:

We mainly discuss the effect of virtual reality on myopia. It is proved that when eyes are in the state of binoc- ular fusion, its refractive power is identical with that of the state of looking at distant objects. We put forward a virtual real- ity myopia intervention therapy which combines VR with b inocular fusion in ophthalmology to cure myopia. The article dis- cusses the theory and implementation of the therapy, introduces the principle of the stereoscopic display technology,discus- ses the difference between the subject and the general display technology in virtual reality,and puts forward thr ee basic ele- ments of the study： binocular fusion theory, immersion produced by parallel parallax and cure parameters designed accord- ing to childrenn psychology. The article presents the implementation of the virtual reality myopia intervention therapy. After the research of children psychology, we  use Visual C＋ ＋, Open Inventor to write software, which can attract children＇s at- traction. The software has the function of image movement, stereosscopic display, man-machine conversion and so on,which meets the need of virtual reality. It provides a helpful innovation for curing myopia. It is mean  ingful in both theory and practice.

Key words: virtual reality, stereoscopic display, preventing myopia, children psychology
