Visual Response Training With Divided LED Arrays for Amblyopia
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing treatments for amblyopia, such as eye patches, drops, glasses, and surgery, are inadequate in effectively improving visual tracking, depth perception, and peripheral vision in children, and existing devices lack a vision divider panel to prevent simultaneous viewing with both eyes.
Innovation Solution
A visual response training device with a centrally disposed vision divider panel and parallel LED arrays, allowing each eye to view a separate array, and a pivotable light bar for varying viewing angles, combined with a programmable control unit for sequential LED activation, to diagnose and treat amblyopia.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional treatments (eye patches, drops, glasses, surgery) are used for amblyopia, then treatment is provided, but visual tracking, depth perception, and peripheral vision are not effectively improved
Solution Approach 1:
The device divides the visual field into separate zones using a vision divider panel, allowing each eye to be trained independently on separate LED arrays. This segmentation enables targeted treatment of the non-dominant eye while preventing it from viewing the dominant eye's stimulus, directly addressing the inadequacy of traditional treatments.
Solution Approach 2:
The system changes the parameters of visual stimulation by using programmable LED arrays that can vary in color, intensity, sequence, and timing. The control unit enables dynamic adjustment of stimulation parameters to optimize treatment effectiveness, moving beyond the static nature of traditional treatments.
2Device complexity
If a single linear array of LEDs is used without a vision divider panel, then device simplicity is maintained, but simultaneous viewing by both eyes occurs preventing effective non-dominant eye training
Solution Approach 1:
The device is segmented into two separate LED arrays positioned on opposite sides of a vision divider panel. This physical segmentation ensures that each eye can only view its designated array, enabling effective non-dominant eye training while maintaining a relatively simple overall device structure.
Solution Approach 2:
The vision divider panel acts as an intermediary element that physically separates the two LED arrays and prevents cross-viewing between eyes. This intermediary structure is essential for the device's therapeutic function while adding minimal complexity to the overall design.
3Ease of manufacture
If fixed viewing angle is used in the device, then manufacturing simplicity is maintained, but adaptability to different visual conditions and treatments is limited
Solution Approach 1:
The light bar is made dynamically adjustable through a pivotable mounting mechanism that allows the viewing angle to be changed. This dynamic feature enables adaptation to different visual conditions and treatment requirements while maintaining ease of manufacture through a straightforward pivotable joint design.
Solution Approach 2:
The device adds angular dimensionality to the viewing configuration by allowing rotation of the light bar around a pivot point. This dimensional change enables multiple viewing angles without complicating the basic linear array structure, achieving versatility through rotational freedom.

AI summary
A visual response and training device and system comprising a fixed vision divider panel that is configured to sequentially light a plurality of differently colored LED bulbs each separately visible to only one eye of a user to promote visual tracking in a non-dominant eye. The subject device and system can optionally be configured for testing peripheral vision to sequentially light LED bulbs spread over a range of viewing angles ranging up to about 90 degrees laterally from center in each direction from the respective eyes of a user.
