Solution Overview
Problem
Existing ophthalmic lenses for myopic progression provide fixed refractive power and defocus zones, limiting adaptability and visual quality, and there is a need for improved lenses that can enhance visual experience and reduce myopia progression.
Innovation Solution
Incorporating electrically-addressable lens portions that can focus light to different locations, including in front of the retina, allowing for adjustable optical power and enhanced control over myopic progression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed refractive power and fixed defocus zones are used in ophthalmic lenses, then manufacturing is simplified, but adaptability and visual quality are limited
Solution Approach 1:
The patent applies the dynamics principle by incorporating electrically-addressable lens portions that can dynamically change their optical power in response to electrical signals. This allows the lens to adapt its refractive characteristics based on viewing conditions, transitioning between different optical states to provide both distance correction and myopia control as needed, thereby resolving the contradiction between fixed manufacturing simplicity and adaptive performance.
Solution Approach 2:
The patent utilizes parameter changes by enabling the lens portions to alter their optical power parameter electrically. The electrically-addressable portions can change their refractive power between different states (e.g., zero power, positive power, negative power) based on applied electrical signals, allowing the same physical lens structure to provide multiple optical functions and improve adaptability without requiring multiple different lens designs.
2Ease of operation
If fixed defocus zones are used, then lens manufacturing is easier, but visual quality and myopia progression control are compromised
Solution Approach 1:
The patent implements dynamics by making the defocus zones electrically adjustable rather than fixed. The electrically-addressable lens portions can be selectively activated or deactivated, and their optical power can be modulated, allowing the lens to dynamically adjust the amount and location of defocus based on viewing distance and task requirements, thereby improving visual quality while maintaining manageable complexity through electrical control.
Solution Approach 2:
The patent applies universality by designing lens portions that can serve multiple functions depending on their electrical state. The same electrically-addressable portion can provide distance correction, intermediate vision, or myopia control defocus depending on the applied electrical signal, eliminating the need for separate fixed zones for each function and simplifying the overall lens configuration while improving visual quality.
3Reliability
If conventional fixed lenses are used, then the lens structure is simpler, but the ability to control myopic progression is reduced
Solution Approach 1:
The patent employs dynamics to enhance myopia progression control by enabling real-time adjustment of the defocus characteristics. The electrically-addressable lens portions can be programmed to provide appropriate myopic defocus during periods when the eye is most susceptible to progression (e.g., during near work or specific times of day), creating a dynamic treatment regime that adapts to the wearer's visual behavior and improves reliability of myopia control.
Solution Approach 2:
The patent incorporates feedback mechanisms where the lens system can respond to visual cues or external signals to adjust the optical power of the lens portions. This feedback control allows the lens to automatically adjust its myopia control function based on detected viewing conditions, ensuring consistent and reliable myopia progression control while managing complexity through automated electrical control systems.
