In the embodiment, the aim of removing the inhibition can be achieved without wearing covering cloth by a way of enabling the amblyopia eyes to obtain stronger visual signals, so that the rejection psychology of the user on training is reduced; can be matched with polarized glasses, red-blue glasses or VR glasses for training.
In this embodiment, the first optotype and the second optotype are equal in size and shape; during initialization, two optotypes are arranged on the same horizontal line and distributed left and right. The first and second optotypes may be humans, animals, plants, or the like.
In this embodiment, the training interface may be initialized according to the polarized glasses, the red-blue glasses, and the VR glasses, respectively, so as to achieve the effect of binocular vision separation; by separating vision by two eyes, only the left eye can observe the left visual target, and the right eye can observe the right visual target. The binocular vision can be realized by filtering red and blue light through red and blue glasses, filtering transverse waves and longitudinal waves through polarized light glasses, directly imaging a single eye screen through VR glasses, and the like.
In this embodiment, carrying different screens for training requires corresponding processing at the time of initialization. Since the red-blue glasses need to filter specific colors to achieve the split vision effect, the colors need to be set to red-blue colors, wherein the left eye sees blue and the right eye sees red; for polarized light screen, only the initial picture width is compressed to half of the original picture width, and the left and right eyes are respectively placed into the videos needed to be seen by the left and right eyes by taking the central line of the screen as the symmetry axis. Wherein the video width is also compressed to one half of the original. When the polarized light screen is transmitted, 2 pictures with consistent width and height are divided by the central line, the width of the left picture and the right picture is automatically set to be twice of the original width, the pictures on the left side and the right side are overlapped, and different polarized light waves are transmitted; the VR glasses only need to put the video to be displayed on the screens with independent left and right eyes respectively.
