Color-Layer Image Processing for Myopia and Hyperopia Cues
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for addressing myopia and hyperopia in children and adolescents provide only moderate results, and there is a need for alternative approaches to assist emmetropization effectively.
Innovation Solution
An image processing system that manipulates digital images by selectively blurring or sharpening color layers (red, green, and blue) based on the refractive error of the subject to create cues for the eye to adjust its dimensions naturally towards emmetropia, using a display to present manipulated images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional methods (spectacles, multi-focal spectacles, bi-focal soft contact lenses, medications) are used to address myopia and hyperopia, then some correction is achieved, but the results are only moderate and not sufficiently effective
Solution Approach 1:
The patent applies parameter changes by selectively blurring specific color layers (red, green, or blue) in displayed images based on the subject's refractive error type and degree. This modifies the optical parameters presented to the eye, creating customized chromatic defocus cues that stimulate emmetropization more effectively than conventional uniform correction methods.
Solution Approach 2:
The invention implements local quality by applying different blur levels to different color layers within the same image. Instead of uniformly correcting all wavelengths, the system selectively applies chromatic defocus to specific color channels (e.g., blurring only the blue layer for myopic subjects), creating localized optical quality variations that target specific emmetropization pathways.
2Ease of operation
If the eye elongates to reach emmetropia from hyperopia, then distant vision improves, but excessive elongation causes myopia
Solution Approach 1:
The system implements feedback by continuously monitoring the subject's refractive status and adjusting the blur applied to different color layers accordingly. The processing unit modifies the chromatic defocus cues based on the subject's current emmetropization progress, providing dynamic feedback that prevents excessive eye elongation while maintaining natural vision development.
Solution Approach 2:
The invention applies preliminary anti-action by preemptively applying chromatic defocus cues that counteract the tendency for excessive eye elongation. For myopic subjects, the system blurs specific color layers to create optical feedback that signals the eye to reduce elongation, preventing the harmful progression of myopia before it fully develops.
3Reliability
If digital images are processed by selectively blurring color layers, then emmetropization is assisted, but the image processing complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the digital image into separate color layers (red, green, blue) and processing each layer independently with different blur levels. This segmentation approach simplifies the processing complexity by handling each color channel separately rather than processing the entire image uniformly, while still achieving effective emmetropization assistance.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system assists emmetropization by creating optical cues that help the eye elongate or stop elongating appropriately, potentially preventing or limiting myopia and hyperopia, promoting optimal relaxed vision without the need for corrective lenses.
Implementation Method 1
The refractive components of the eye project the different wavelength components of an external scenery in focus at different depths, a phenomenon called longitudinal chromatic dispersion
