Visual Processing Aid With Asymmetric Optical Field Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for addressing dyslexia and visual processing disorders fail to effectively compensate for the symmetrical pattern of rods and cones in the retina, lack of a dominant eye, and do not eliminate reversals, inversions, blurring, and moving text, often being expensive, cumbersome, or requiring extensive intervention.
Innovation Solution
A visual processing aid with a housing and anchoring member that provides a uniform change in property, such as opacity or tint, to differentiate visual information from both eyes and fields, allowing the brain to assimilate and process visual information accurately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If eye patches or eyeglasses that block peripheral vision are used, then the brain receives less visual information to process, but the device does not eliminate reversals, inversions and moving text, and may create safety hazards by blocking peripheral vision
Solution Approach 1:
The visual processing aid applies different optical properties to different regions of the visual field. Specifically, it creates an asymmetrical optical environment where one eye or one visual field receives modified visual input (with altered opacity, tint, or focal properties) while the other eye or visual field receives unmodified or differently modified input. This local differentiation helps the brain distinguish between the symmetrical patterns of rods and cones without completely blocking any visual information, thereby maintaining safety while improving processing.
Solution Approach 2:
The device introduces asymmetry into the previously symmetrical visual input from both eyes. By applying different optical modifications to each eye or each visual field (such as different tint levels, opacity gradients, or focal adjustments), the brain receives asymmetric visual information that breaks the confusing symmetry pattern. This asymmetrical processing helps eliminate reversals and inversions while maintaining full peripheral vision for safety.
2Manufacturing precision
If eyeglasses with restricted openings (hole and slit) are used, then reading focus is improved, but reading speed is lost because only a small segment of text can be seen at once
Solution Approach 1:
The visual processing aid employs dynamic optical properties that can adjust focus and field of view. Rather than fixed restricted openings, the device uses adjustable or adaptive optical elements (such as variable opacity regions, adjustable tint, or dynamic focal points) that can expand or contract the effective viewing area based on reading needs. This dynamic approach maintains precise focus when needed while allowing broader text visibility to preserve reading speed.
Solution Approach 2:
The device addresses the two-dimensional conflict between focused viewing and broad viewing by introducing a third dimension - optical density or transparency variation. Instead of restricting the horizontal and vertical extent of the opening, the invention varies the opacity or tint across different regions, allowing the entire text area to remain visible while certain regions provide enhanced focus through selective optical filtering. This dimensional approach preserves both focus precision and reading speed.
3Reliability
If vision therapy or extensive teaching methods are used, then some improvement in visual processing may be achieved, but the approach is time consuming and requires intense adult intervention
Solution Approach 1:
The visual processing aid enables self-service by providing immediate, automatic optical correction that does not require continuous adult intervention or lengthy therapy sessions. The device independently processes visual information in real-time, allowing users to self-regulate their visual input without external guidance. This transforms a previously intensive, time-consuming therapeutic process into an autonomous, on-demand solution that users can apply independently.
Solution Approach 2:
The invention replaces the mechanical, time-intensive system of vision therapy and manual teaching with an optical system that automatically corrects visual processing issues. Instead of relying on repetitive exercises and adult-guided activities, the device uses optical principles (asymmetrical filtering, focal adjustment, or transparency variation) to directly modify visual input and eliminate the need for extensive therapeutic intervention, dramatically reducing time requirements.
4Loss of information
If colored lenses or differently-tinted lenses for each eye are used, then visual differentiation may be improved, but the devices are expensive and do not eliminate reversals, inversions and moving text
Solution Approach 1:
The visual processing aid achieves visual differentiation by modifying optical parameters such as opacity, transparency, or focal length rather than relying solely on color filtering. By varying these parameters asymmetrically between eyes or visual fields, the device creates sufficient visual differentiation to eliminate confusion from symmetrical retinal patterns without requiring complex colored lens systems. This parameter-based approach reduces manufacturing complexity and cost while maintaining effectiveness.

AI summary
Exemplary visual processing devices and methods are disclosed. Example devices may include a visual processing aid having at least one anchoring member (76) that is attached to a housing (74) such that the anchoring member is positioned proximal to a line of sight, between a retina of a user and a scene. The anchoring member has one or more straight-line sloping branches (80), to enable a user to assimilate visual information from left and right visual fields of one eye, and from both eyes, quickly and accurately and produce an image of a scene. Other devices and methods are described and shown.
