Color Changing Eyewear Lens Selection System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eyewear lenses lack customization to match individual facial features and ambient lighting conditions, often having fixed colors that do not adapt to changes in solar flux or temperature, failing to provide optimal aesthetic and functional performance.
Innovation Solution
A system that captures a digital image of the consumer's face to simulate and select customized color-changing lenses using photochromic or thermochromic materials, allowing for initial and final color selection based on temperature and light conditions, with the ability to mix different dyes for personalized preferences, enabling the production of eyewear with adaptive color changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional eyewear lenses with fixed color are used, then manufacturing simplicity is maintained, but adaptability to different ambient lighting conditions and temperature is lost
Solution Approach 1:
The patent applies parameter changes by incorporating photochromic and thermochromic materials that alter the optical properties of the lens based on environmental parameters. The photochromic material changes transmission in response to UV light exposure, while the thermochromic material changes transmission in response to temperature variations, enabling the lens to adapt to different ambient conditions without complex mechanical structures.
Solution Approach 2:
The patent uses composite materials by combining photochromic and thermochromic materials within the lens structure. This composite approach allows the lens to simultaneously respond to multiple environmental stimuli (UV light and temperature), achieving versatile adaptability while maintaining a unified lens structure rather than requiring separate adjustable components.

3Adaptability or versatility
If photochromic or thermochromic materials are used to enable color changing, then adaptability to environmental conditions is improved, but the ability to provide personalized color selection for different facial features is reduced
Solution Approach 1:
The patent applies preliminary action by providing a software application that enables consumers to simulate and select their preferred lens colors and shades before purchase. The application allows users to visualize how different photochromic and thermochromic material combinations will appear under various conditions, enabling personalized selection without requiring access to multiple physical lens samples.
Solution Approach 2:
The patent uses copying by creating a digital representation of the lens appearance through software simulation. The application generates visual copies of how the lenses will look in different environmental conditions based on the selected photochromic and thermochromic material combinations, allowing consumers to make informed personalized selections without physically testing each option.
4Adaptability or versatility

AI summary
A system for facilitating a consumer's selection of customized color-changing lenses for eyewear, or windows, captures a digital color image of at least the face of the consumer and displays that color image to the consumer on a video display while superimposing a pair of lenses over the eyes. The display simulates the color of the superimposed lenses when made of a selected photochromic or thermochromic material. The color of the superimposed lenses is changeable, in response to consumer-controlled inputs, over a range between (a) an initial color for the lenses when subjected to at least one of (i) a first predetermined temperature and (ii) a first predetermined light condition, and (b) a final color for said lenses when subjected to at least one of (i) a second predetermined temperature higher than said first predetermined temperature and (ii) a second predetermined light condition brighter than said first predetermined light condition.
