Research On Visual Correction System Based On Virtual Reality Technology

In the past two decades,with the emergence of electronic products such as smart phones,the time spent on the eyes of young people has increased,causing a series of eye diseases such as myopia.The existing traditional vision correction methods have great inconvenience and low intelligence due to the limitations of training methods and training equipment,which severely restrict the user’s treatment experience and reduce the treatment effect.Therefore,the research of new vision correction methods has very important scientific research value and social significance.In this context,this thesis designs and develops a vision correction system based on virtual reality technology.In the virtual scene,based on the active movement of traditional eye exercises,a correction method for extraocular muscles is proposed;at the same time,fully study the regulation mechanism of intraocular muscles on vision,combined with the latest theoretical research,designed a training method to exercise the intraocular muscles,finally,the hand-eye-brain coordination interactive training is introduced,and the visual memory module and the visual comprehensive training module are designed to improve The user’s visual following,visual memory and other visual functions.Compared with the traditional visual function module,this system is more intelligent and has the function of automatically adjusting the difficulty according to the user’s training time,which increases the user’s training enthusiasm,guarantees the correction effect and improves the user’s training experience.This system uses 3DMAX and Unity3 d to build a three-dimensional scene model.With the help of Unity3 d technology,Player Prefs database technology and network communication technology,it completes the eye muscle training visual target movement,logic control,storage training data and Android remote control functions.Experimental results show that the system has obvious correction effects for pseudomyopia and low-grade myopia users,and the vision correction method realized by virtual reality technology can effectively increase the user’s compliance with treatment and improve the user’s correction experience.
