Eyewear Indicators That Change Color for Exam and Lens Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyewear devices do not effectively alert users about the need for an eye examination or a change of frame or lens, which is crucial for maintaining optimal visual correction and preventing conditions like myopia progression in children and early detection of eye pathologies in adults.
Innovation Solution
Incorporating indicators in eyewear devices that change color or area in response to stimuli such as time, light, temperature, or mechanical stress to signal the need for an eye examination or frame/lens change, with indicators positioned on various parts of the eyewear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chronochromism or color change mechanisms are used in eyewear devices, then the ability to alert users about eye examination needs is improved, but the device complexity increases
Solution Approach 1:
The patent applies color change mechanisms (chronochromism) to indicators in the eyewear device that change color over predetermined time periods or in response to stimuli, providing a reliable visual alert system for eye examination needs while maintaining relatively simple device architecture
Solution Approach 2:
The patent uses indicators that replicate or copy the visual signaling function from food industry chronochromism applications, adapting a proven alerting mechanism to the eyewear context without requiring complex new systems
2Measurement precision
If multiple indicators with different stimuli are incorporated, then the measurement precision of monitoring needs is improved, but the device complexity increases
Solution Approach 1:
The patent divides the monitoring function into multiple separate indicators, each responding to different stimuli (time, light, temperature, mechanical stress), allowing precise monitoring of various parameters independently while keeping each indicator relatively simple
Solution Approach 2:
The eyewear device incorporates indicators that can respond to multiple types of stimuli, creating a multi-functional monitoring system that provides comprehensive eye health monitoring through a unified device structure
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
Ensures timely eye examinations and frame/lens changes, reducing myopia progression in children and improving visual correction and early detection of eye pathologies in adults.
Implementation Method 1
Different technologies can be used to generate chronochromism. US 2007/0064541 and US 7,232,253 disclose examples of elapsed time indicator devices.
Implementation Method 2
WO 2007/013105 A1 discloses a frame for spectacles comprising heat-sensitive material, normally opaque and capable of becoming transparent when a thermal colour change threshold is exceeded.
