Document Type and Number:
WIPO Patent Application WO/2019/169553
Kind Code:
A1
Abstract:
A training and rehabilitation device for amblyopia is implemented in a virtual reality device (10), and comprises a VR headset main body comprising a left portion (13) and a right portion (14). Each of the left portion and the right portion is provided with an optical lens assembly, a display screen, a control module and a storage device. A video (20) is stored in the storage device. The optical lens assembly comprises a first lens (131), a second lens (132), and a third lens (133). A first engagement recess (134), a screen-shielding shutter (135) and a second engagement recess (136) are sequentially arranged at each of the left portion (13) and the right portion (14) in a viewing direction of the eyes. The first engagement recess (134) is used to fix the first lens (131). The screen-shielding shutter (135) is electrically connected to the control module to realize opening and closing of the screen-shielding shutter (135). The second engagement recess (136) is used to fix the second lens (132). The second lens (132) is used to blur a left screen (11) or a right screen (12) so as to reduce visibility of a dominant eye. A display screen is blocked or blurred to train, and thereby correct, the vision of an amblyopic eye, improving the perception of distance and speed in three-dimensional space.
