Push-Pull Perceptual Learning for Sensory Eye Dominance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Binocular imbalance and sensory eye dominance can lead to degraded binocular visual processing and reduced stereopsis, with existing treatments being inadequate for correcting these conditions.
Innovation Solution
A Push-Pull perceptual learning technique that stimulates the weak or non-dominant eye through interactive tasks while suppressing the strong or dominant eye, using visual stimuli such as grating discs with varying orientations and phase shifts, presented via a computer-implemented method to improve binocular balance and stereopsis.

Engineering Contradiction Analysis
1Reliability
If traditional treatment methods are used for binocular imbalance, then some improvement may be achieved, but the treatment is inadequate and does not effectively correct sensory eye dominance
Solution Approach 1:
The treatment method segments the binocular vision training into distinct components: presenting different visual stimuli to each eye separately, with the non-dominant eye receiving stimuli that promote dominance while the dominant eye receives suppressing stimuli. This segmentation allows targeted intervention for each eye's specific functional needs.
Solution Approach 2:
The invention inverts the traditional approach by actively suppressing the dominant eye while stimulating the non-dominant eye. Instead of trying to strengthen the weak eye in isolation, the method uses interocular suppression to reduce the dominant eye's influence, thereby allowing the non-dominant eye to gain dominance through relative strengthening.
2Measurement precision
If the dominant eye is stimulated to improve visual acuity, then the strong eye's performance improves, but interocular imbalance worsens and sensory eye dominance increases
Solution Approach 1:
The treatment applies different visual stimuli and processing to each eye based on its individual characteristics. The non-dominant eye receives stimuli designed to promote dominance (such as high-contrast patterns or motion stimuli), while the dominant eye receives suppressing stimuli. This local differentiation addresses each eye's specific functional state rather than applying uniform treatment.
Solution Approach 2:
The method changes key parameters of visual stimulation including contrast levels, temporal frequency, spatial frequency, and stimulus duration for each eye. By adjusting these parameters differently for the dominant and non-dominant eyes, the treatment shifts the balance of interocular competition in favor of the non-dominant eye.
3Reliability
If equal contrast stimuli are presented to both eyes, then binocular perception is optimized, but this approach cannot correct unbalanced interocular inhibition
Solution Approach 1:
The treatment applies preliminary anti-action by pre-compensating for the unbalanced interocular inhibition through unequal stimulus presentation. Before attempting to achieve equal binocular perception, the method first addresses the underlying imbalance by suppressing the dominant eye's excessive influence and stimulating the non-dominant eye, thereby creating the conditions necessary for balanced binocular function.

AI summary
The present invention relates to systems and methods for providing a Push-Pull perceptual learning technique to a subject demonstrating sensory eye dominance (SED), amblyopia, poor stereopsis, and the like. More specifically, the weak eye of the subject is forced to become dominant, while visualization in the strong eye is suppressed over the course of a treatment regimen. Such systems and methods are shown herein to result in a perceptual learning and a reduction of interocular imbalance or SED, as well as an improvement in the visual characteristics typically associated with amblyopia, poor stereopsis and similar visual deficiencies.
