Abstract

The invention discloses an external head-mounted VR device for improving eyesight. The device includes a fixing device, an exterior cover, a display screen, a lens group, a lens adjusting device, an eyeball tracker, a head tracking device, an image storage module, a central processing module and a wireless communication interface. The lens group includes first and second lenses respectively corresponding to eyeball positions and a lens frame. The display screen is located in front of the lens group. The eyeball tracker is for tracking a focus point of eyeballs on the display screen according to the eyeballs and features around the same. The center processing module adjusts the image definition at and around the focus point of the eyeballs in the display screen according to the focus point of the eyeballs. The central processing module controls the rotation of the image displayed in the display screen with the rotation of the head according to the head motion detected by the head tracking device. The wireless communication interface is connected wirelessly with a control terminal. The control terminal is equipped with control software. A plurality of treatment modes are built in the control software.
