Wearable AR Eye Diagnostics with Light Reflection Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ophthalmic devices are large, bulky, and expensive, limiting their accessibility for patients, and often require patients to visit a doctor's office for diagnosis and treatment, which can lead to delayed care and increased risks of mis-diagnosis.
Innovation Solution
A user-wearable diagnostic health system featuring a frame with an augmented reality display, a light detector, and a processor that conducts health analyses based on light detected from the user's eye, allowing for portable and convenient eye examinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional ophthalmic devices are used, then diagnostic accuracy is maintained, but device portability and patient accessibility deteriorate
Solution Approach 1:
The ophthalmic diagnostic system is divided into separate functional modules: a head-mounted display unit for presenting diagnostic information, a portable imager for capturing eye images, and a processing system for analysis. This segmentation allows each component to be independently optimized for portability while maintaining diagnostic capability.
Solution Approach 2:
The patent introduces an intermediary processing system that receives images from the portable imager and performs diagnostic analysis remotely. This intermediary approach allows the core diagnostic functionality to be separated from the imaging device, enabling portable imaging while maintaining accurate diagnosis through centralized processing.
2Reliability
If patients visit doctor's office for eye examinations, then professional diagnosis is obtained, but time loss and delayed care increase
Solution Approach 1:
The system enables preliminary eye examinations and diagnostic imaging to be performed by patients at home before visiting the doctor. The portable imager and head-mounted display allow patients to complete basic diagnostic procedures independently, with results transmitted to healthcare providers for review, thereby reducing the time needed for actual clinical visits.
Solution Approach 2:
The system incorporates feedback mechanisms where diagnostic images and analysis results are automatically transmitted to healthcare providers. This feedback loop enables continuous monitoring and timely intervention, reducing the delay between symptom onset and professional diagnosis while maintaining diagnostic reliability.
3Measurement precision
If patients remain in fixed position for lengthy procedures, then measurement precision is maintained, but patient comfort and error risk worsen
Solution Approach 1:
The head-mounted display and imaging system are designed to be dynamic and adaptable to patient movements rather than requiring fixed positioning. The portable nature of the devices allows examination in various positions and settings, maintaining measurement precision through software compensation while significantly improving patient comfort.
Solution Approach 2:
The system uses parameter changes in image processing and analysis algorithms to maintain measurement precision regardless of patient position. By adjusting diagnostic parameters dynamically based on captured images, the system achieves accurate eye measurements without requiring patients to maintain rigid positions throughout lengthy procedures.

AI summary
Configurations are disclosed for a health system to be used in various healthcare applications, e.g., for patient diagnostics, monitoring, and/or therapy. The health system may comprise a light generation module to transmit light or an image to a user, one or more sensors to detect a physiological parameter of the user's body, including their eyes, and processing circuitry to analyze an input received in response to the presented images to determine one or more health conditions or defects.
