Myopia Management Spectacles with Segmented Optical Cues
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spectacle designs for myopia management often cause visual disturbances and are not cosmetically appealing to children and young adults, while also being costly, which limits their accessibility and effectiveness in managing myopia progression.
Innovation Solution
The development of a set or kit comprising pairs of myopia management spectacles or spectacle fronts, and impermanent auxiliary optical films or elements, configured to provide toric, astigmatic, or asymmetric optical directional cues as optical stop signals to decelerate myopia progression. These elements are designed to be used in conjunction with standard single vision spectacles and are prescribed under a care regimen that provides temporal and spatial variation to the directional cues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional myopia management spectacle designs (bifocals, progressive lenses, peripheral plus lenses) are used, then myopia progression can be controlled, but visual disturbances occur and cosmetic appeal is compromised
Solution Approach 1:
The spectacle lens is divided into two functional segments: a first region with negative optical power for correcting myopic refractive error, and a second region with positive optical power for providing myopia progression control. This segmentation allows each region to perform its specific function without interfering with the other, eliminating visual disturbances while maintaining cosmetic appeal.
Solution Approach 2:
Different regions of the spectacle lens are assigned different optical properties: the first region has negative power optimized for clear distance vision, while the second region has positive power optimized for myopia control. This local differentiation of optical quality enables simultaneous achievement of visual comfort and myopia management efficacy.
2Reliability
If traditional myopia management spectacle designs are used, then myopia progression can be controlled, but the cost is high limiting accessibility
Solution Approach 1:
The invention combines two separate optical functions (myopia correction and myopia control) into a single integrated spectacle lens design. By merging these functions into one lens rather than requiring multiple separate lenses or complex progressive designs, the manufacturing process is simplified and costs are reduced while maintaining effective myopia progression control.
3Ease of operation
If standard single vision spectacles are used, then visual performance is excellent, but they do not address the underlying cause of excessive eye growth
Solution Approach 1:
The spectacle lens is designed to perform multiple functions simultaneously: it corrects myopic refractive error through the first region with negative power, and controls myopia progression through the second region with positive power. This multi-functionality allows the same lens to maintain excellent visual performance while actively addressing the underlying cause of excessive eye growth.

Function Achieved in This Case
The proposed solution effectively reduces the progression of myopia by providing a temporally and spatially varying optical stop signal, thereby maintaining consistent efficacy over time without compromising visual performance or aesthetics, and at a more affordable cost.
Implementation Method 1
a first region with negative optical power for correcting myopic refractive error and a second region with positive optical power for providing myopia progression control
