[0019] 2. The resolution of visual targets arranged in rows is worse than that of single visual targets
Despite great strides in understanding the mechanisms of amblyopia treatment, targeted treatment options for amblyopia symptoms remain
[0037] Specifically, it is still not possible to determine the therapeutic strength and therapeutic effect of the occlusion method

Embodiment 1

[0064] As shown in FIG. 5( a ), the system for treating visual dysfunction by regulating eye dominance also includes a computer-controlled audio processor 30 , a power amplifier 35 and a speaker 40 to increase audio signals and relieve fatigue.

[0065] The system for treating visual dysfunction by regulating the eye advantage also includes 3D glasses 45 and its signal receiver 50, and the 3D glasses 45 and its signal receiver 50 can receive the left-eye frame image L and the right-eye frame image presented by the graphic image display device 20 R.

[0066] The graphic image display device 20 may be one or more of a 2D display, a 3D display, a projector or a 3D TV. If the left and right eye channels of the video file contain disparity information, it will be displayed on a 3D monitor as a 3D effect. It mainly depends on whether you are playing 2D video or 3D video.

[0067] The graphic movie database 5 may contain 3D movies, and the image decoder 10 decodes the video signals...

Embodiment 2

[0069] As shown in Figure 5(b), the system for treating visual dysfunction by regulating eye dominance is based on binocular asynchronous visual stimulation training and correction, including: image movie database 5, image decoder 10, image controller 15 controlled by computer, graphic image display Equipment 20, computer graphic real-time generation software system 25. The graphic movie database 5 includes natural scene pictures, video clips, and movie clips or complete movies taken from various perspectives. The files can be stored in the file system or database in a certain compressed manner. The rich graphic image database can increase the fun of training , to reduce the disgust brought by long-term training to the trainee.

[0070] The computer graphics real-time generation software system 25 can generate simple computer graphics in real time, such as grating, light spot or other geometric graphics images.

[0071] In the experiment, a display with a refresh rate of 120H...

Embodiment 3

[0073] As shown in Figure 5(c), the display device does not distinguish between left and right display, and can display different image contents to the trainee, including but not limited to gratings of different orientations and light spots of different sizes generated by the computer graphics real-time generation software system 25, And digitized contents such as images and videos stored in the image and movie database 5 .

[0074] The image movie database 5 contains natural still images and moving images captured by digital cameras and camcorders.

[0075] There is no fixed distance between the trainee and the display device, and the distance that the trainee feels comfortable shall prevail. Train for half an hour to an hour every day, and continue to train for half a month to get better therapeutic effects. Before and after the training of this system, the trainer's eye dominance will be tested according to the ophthalmology standard method to accurately judge whether the ...

Abstract

The invention relates to a system for treating visual dysfunction by adopting ocular dominance regulation. The system comprises a computer-controlled image controller (15) connected with an output end of an image decoder (10). An input of the image decoder (10) is connected with an image movie database (5) and / or a computer graphics real-time software system (25), and the computer-controlled image controller (15) is connected with at least one graphics and image display system (20). Time intervals of stimulation received by binocular vision are specified in a time window to allow a weaker vision to receive stimulation of visual images earlier than the other more dominant vision. In the system, time scope displayed by the controller is accurate to millisecond and the time window is preferably accurate to plus-minus eight milliseconds. A display device provides stimulation time of the binocular vision in different order, so that the defects of lack of therapeutic effect and proneness to relapse in existing screening method are overcome, and treatment of weak sight and other visual dysfunction is realized.

Description

technical field [0001] The invention relates to a visual stimulation software system for regulating the balance of binocular dominance. Specifically, it can be applied to improve and treat various visual dysfunctions caused by unbalanced binocular visual input, including amblyopia. Background technique [0002] Human binocular stereo vision is formed in this way: both eyes look at an object at the same time, and the eyes of both eyes cross at one point, which is called the fixation point, and the light points reflected from the fixation point back to the retinas of the left and right eyes are called corresponding points. ). Since there is a distance between the two pupils of a person (the average value is 50-75mm), the relative positions of the left and right eyes (Relative Position) are different for the same scene, which produces binocular disparity (Binocular Disparity), that is, the left and right eyes see What you get is a different image. The visual information from...
