Gvw is a new kind of near-sighted machine, using the bat approach to restoration of visual training, using an international 3d image technique, to re-reflect microcomputer controlled cursors through lenses into mirrors, to see the cursors automatically adjusted to a few metres, tens of metres, hundreds of metres, or even infinite distances in the dark chamber module, to show the eyes close to each other, 20 seconds to the next week, to re-create the bat visual training act in instruments, to exercise lashes, to relax crystals, to control near-sighted development and to protect the eyesight. Using computer virtual technology, the gvw visual training unit has achieved the re-enactment of the bates visual training restoration act, which has brought to light the world's shocking visual care. Gvs uses international 3d video technology to "3d visual restoration training" for children's eyes. The microcomputer controlled cursor, which is retrospected through the lens to the mirror, using the computer virtual realization technique, is automatically adjusted to a few metres, tens of metres, hundreds of metres, or even infinite distances in the dark chamber module, allowing the eyes to look further and further away, from a distance and closer, 20 seconds to a week, which is equivalent to gymnastics for the lashes and the crystals, which restore the impact of the lashes, thereby increasing the child's vision. The way to see the near-sighted is to exercise lashes to restore the sight. Gvvs, which is a visual training recovery instrument, uses the bates visual training restoration method, using international 3d video technology and computer reality virtual technology to allow eyes to see the near end of a cycle of exercise, thus reinforcing the lashes, relaxing the crystals and achieving the goal of closer-sightedness. The computer-coded pulse technology, which is the exclusive preserve of gvw, simulates traditional acupuncture, acts in the eye holocular position, eliminates eye fatigue and removes the external causes of near-sightedness; and defusing the aerobic channels between the eye and the liver and kidneys so that the nutrients flow to the eye and removes the internal causes of near-sightedness. The application of gvvs to young people's false, real and mixed near-sighted visits, as well as the reduction of headaches, dizziness, insomnia, memory loss, cerebral fatigue and visual fatigue caused by nervous decay, have a significant impact on the prevention of near-sightedness among young people. An alarming feeling of consultation in the near-sighted for external causes。
