Kind Code:
A1
Abstract:
A control method and a control apparatus for a visual function diagnosis and treatment VR device, and a VR device. The control method for the visual function diagnosis and treatment VR device comprises the following steps: acquiring optotype image information on a display component; according to a preset time interval, controlling the distance between a first lens group (200) and a second lens group (300) to move at equal intervals or unequal intervals within a preset distance range. During adjustment, the optotype image on the display component can be imaged in human eyes by means of the first lens group (200) and the second lens group (300) in sequence, so as to form different adjustment stimuli for human eyes. The problems that the existing examination and training devices are complicated to operate, and have non-ideal examination and training effects and poor user experience can be alleviated.
