Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is challenging for eye care professionals to effectively evaluate the long-term efficiency of myopia control products for individual wearers, given the varying responses of each individual to different products and the long-term nature of myopia progression.
Innovation Solution
A method involving placing the wearer in myopia-inducing conditions allows for rapid and quantifiable changes in myopia indicators, enabling eye care professionals to assess the efficiency of myopia control products within a short time frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If myopia control products are used for long term evaluation, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing myopia inducing conditions and using dual imaging to capture baseline and test images. This preparation allows the actual efficiency evaluation to be completed rapidly without requiring long-term observation periods, thus resolving the contradiction between measurement precision and time consumption.
Solution Approach 2:
The patent replaces the traditional mechanical/time-based long-term observation system with an optical measurement system using dual imaging and image processing. This substitution enables rapid quantification of myopia control efficiency through optical path differences, eliminating the need for prolonged evaluation periods while maintaining measurement accuracy.
2Adaptability or versatility
If individualized myopia control product selection is implemented, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent introduces an intermediary computational processing system that automatically analyzes dual images, calculates optical path differences, and determines myopia control efficiency. This intermediary processing layer handles the complexity of individualized evaluation, making the system adaptable to different wearers without requiring complex manual assessment procedures.
Solution Approach 2:
The patent uses image copying and comparison techniques, where a reference image is created under standard conditions and compared with test images taken under myopia inducing conditions. This copying approach simplifies individualized evaluation by using standardized reference frameworks that can be automatically processed, reducing system complexity while maintaining adaptability.

AI summary
A method of evaluating the efficiency of a myopia control product for a wearer, the method comprising: - an initial myopia indicator providing step S1, during which the initial value of a myopia indicator of the wearer is provided, - a myopia condition step S2, during which the wearer using the myopia control product is placed in myopia inducing conditions, - a resulting myopia indicator determining step S3, during which the resulting value of the myopia indicator of the wearer is determined after the wearer has been placed in the myopia inducing conditions, - an efficiency evaluation step S4, during which the efficiency of the myopia control product is evaluated by comparing the initial value of the myopia indicator and the resulting value of the myopia indicator.
