Dynamic Visual Aberration Correction Using Adaptive Optics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wearable technologies, such as smart glasses, fail to adequately address higher order and dynamic visual aberrations that are not correctable by traditional glasses or contact lenses, particularly those that change with eye accommodation and gaze direction.
Innovation Solution
A system that uses feedback from user responses and eye images to determine defective visual field portions, generating enhanced images and adjusting wearable device configurations, including dynamic display portions, to provide correction and enhancement of the visual field.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional glasses or contact lenses are used, then simple refractive errors can be corrected, but higher order and dynamic visual aberrations cannot be addressed
Solution Approach 1:
The patent employs wavefront sensors and adaptive optics technology that dynamically measure and correct higher order aberrations in real-time. The system continuously adapts to changing visual conditions, including dynamic aberrations that vary with accommodation state and gaze direction, making the correction effective for complex visual defects that static traditional lenses cannot address
Solution Approach 2:
The system changes multiple optical parameters simultaneously including wavefront phase, amplitude, and higher order Zernike coefficients to correct complex visual aberrations. By adjusting these parameters dynamically based on real-time eye measurements, the system can address higher order aberrations beyond the simple spherical and cylindrical corrections provided by traditional glasses
2Ease of manufacture
If static correction methods are used, then manufacturing is simple, but dynamic aberrations changing with accommodation and gaze cannot be corrected
Solution Approach 1:
The system performs self-measurement and self-correction through integrated wavefront sensing and adaptive optics. The device automatically measures the user's specific aberrations and dynamically adjusts correction parameters without requiring manual intervention or complex manufacturing processes for each individual, making dynamic correction accessible while maintaining ease of deployment
Solution Approach 2:
The patent replaces static mechanical lens systems with a dynamic optical system using wavefront sensors, spatial light modulators, and real-time control algorithms. This substitution enables the system to adapt to changing visual conditions through electronic control rather than requiring complex mechanical adjustment mechanisms or custom-manufactured lenses for each user
3Adaptability or versatility
If real-time feedback systems are implemented, then dynamic visual defects can be corrected, but device complexity increases
Solution Approach 1:
The system integrates multiple functions into a single platform: wavefront sensing, adaptive optics correction, visual field mapping, and real-time image enhancement all operate through the same hardware infrastructure. This multi-functionality reduces overall system complexity compared to having separate devices for each function, as the adaptive optics engine serves multiple correction and measurement purposes

AI summary
In certain embodiments, enhancement of a vision of a user may be facilitated. In some embodiments, a visual test presentation including a set of stimuli may be provided to a user. Feedback related to the set of stimuli may be obtained during the visual test presentation. The feedback may be provided to a prediction model, and the prediction model may be configured based on the feedback. Subsequent to the configuring of the prediction model, live video stream data, eye characteristic information, or other information may be provided to the prediction model to obtain a set of modification parameters. A modified version of the live video stream data may be generated and displayed to the user based on the live video stream and the set of modification parameters.
