Sensor-Equipped Myopia Control Glasses for Wear Compliance Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyeglass monitoring systems fail to provide effective feedback on the wearing time and environmental parameters to prevent or slow down myopia progression in children, as they primarily focus on improving vision rather than preventing degradation.
Innovation Solution
A monitoring equipment comprising eyewear with embedded sensors and a processing unit that tracks wearing time, compares it against predetermined data, and provides feedback on treatment efficiency, including advice or alerts through a human-machine interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If special corrective eyeglasses are prescribed to control myopia progression, then the evolution of myopia can be slowed down, but the wearing regularity is difficult to control in children
Solution Approach 1:
The patent implements a feedback mechanism through a sensor that detects whether the eyeglasses are being worn and transmits this information to a processing unit. The system provides feedback to parents or caregivers about the child's wearing compliance, enabling them to monitor and encourage regular wear. This resolves the contradiction by making wearing regularity controllable through external feedback while maintaining the myopia control efficacy of the special lenses.
Solution Approach 2:
The eyeglasses incorporate an autonomous sensor system that automatically detects wearing status without requiring manual input from the child. The processing unit autonomously analyzes sensor data and generates compliance reports, making the monitoring process self-service rather than relying on the child's self-reporting or parental observation. This enables effective wearing regularity control while preserving the therapeutic function of the lenses.
2Measurement precision
If the wearing time of eyeglasses is monitored to improve vision, then vision improvement can be assessed, but it does not address myopia prevention or stabilization needs
Solution Approach 1:
The patent enhances the universality of the eyeglass system by integrating not only myopia control lenses but also environmental sensors that detect lighting conditions and wear duration. The processing unit analyzes both wearing compliance and environmental factors to provide comprehensive myopia management. This multi-functional approach allows the same system to serve preventive, stabilizing, and corrective functions across different myopia stages, rather than being limited to vision improvement assessment only.
3Reliability
If environmental parameters are monitored to evaluate treatment efficacy, then comprehensive treatment assessment is achieved, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the monitoring system into distinct functional modules: wearing sensors embedded in the eyeglass frame, environmental sensors for detecting lighting and other parameters, and a processing unit that separately analyzes each data stream. This modular segmentation enables comprehensive treatment efficacy evaluation through multiple parameters while managing device complexity through organized, independent functional blocks that can be developed and calibrated separately.
Data Source
AI summary
A monitoring equipment including an eyewear that includes a frame, at least one lens that is fixed to the frame and that is able to change the natural evolution of an optical deficiency, a wearing sensor able to determine if the eyewear is being worn by a wearer, and a processing unit that is programmed to acquire the data determined by the wearing sensor, deduce therefrom a parameter relative to the length of time the wearer has worn the eyewear during a predetermined period, and compare said parameter with at least a predetermined datum to determine a level of efficiency of the optical deficiency treatment.
