Intelligent Vision Test (IVT) is a wall mount medical device that achieves the precision and convenience of vision testing with automation and sensing systems, which simplifies the cumbersome mode switching and calculation process. Through the fitting suggestions and voice interaction of the trial lenses, the glasses wearers have the best choice of lenses; the screen is designed to be lifted and stretched, which can meet the measurement of adults and children at one time. The goal is to reduce the workload of medical staff and make the test smoother and more convenient. Each testing mode has been set up for the connection process, improving the fluency of detection and reducing tedious switching procedures. Through the high-quality vision detection process, the maintenance of the testeets' vision health is improved, and at the same time, the medical staff has a good working quality and employment environment.
