Adhesive Optical Corrector Sticker for Single-Vision Lens Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for Presbyopia, such as multifocal and progressive eyeglasses, are costly and require professional adaptation, making them inaccessible to many who need them.
Innovation Solution
A clear elastic optical corrector sticker is applied to regular single-vision spectacles, either during production or by the customer, to convert them into progressive or multifocal lenses, featuring different optical powers in various regions or a graded index profile, allowing for self-application or application by a sales representative.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional multifocal or progressive eyeglasses are used to treat Presbyopia, then vision correction is achieved, but cost and requirement for professional adaptation increase
Solution Approach 1:
The patent enables customers to apply the progressive lens conversion kit themselves at home without requiring professional optometrist intervention. The kit includes all necessary components and instructions for self-application, eliminating the need for complex professional adaptation processes while maintaining effective vision correction.
Solution Approach 2:
The patent uses a disposable adhesive film layer that can be easily applied and removed. This single-use adhesive layer simplifies the overall system by eliminating the need for permanent, complex mounting mechanisms, thereby reducing professional adaptation requirements and making the solution more accessible to consumers.
2Reliability
If conventional multifocal or progressive eyeglasses are used to treat Presbyopia, then vision correction is achieved, but cost increases
Solution Approach 1:
The patent divides the progressive lens system into separate components: a base single-vision lens and a separate adhesive film layer containing the progressive power gradient. This segmentation allows for cheaper manufacturing of individual components that can be assembled by the consumer, reducing overall cost while maintaining vision correction effectiveness.
Solution Approach 2:
The patent changes the physical state and optical parameters of the adhesive film layer to create different lens powers across its surface. By controlling the thickness, curvature, and material properties of the adhesive layer, the system achieves multifocal functionality without requiring expensive precision optics, thereby reducing manufacturing cost.
3Ease of manufacture
If a progressive lens conversion kit is applied by the customer themselves, then cost is reduced and accessibility is improved, but application accuracy and reliability may be compromised
Solution Approach 1:
The patent includes an adhesive film layer as an intermediary component that simplifies the application process. This pre-prepared adhesive layer acts as a mediator between the base lens and the progressive power gradient, making it easier for consumers to apply accurately at home without requiring complex alignment procedures or professional expertise.
Solution Approach 2:
The adhesive film layer is pre-prepared with the progressive power gradient and alignment features before being provided to the consumer. This preliminary action ensures that when the consumer applies the kit at home, the critical precision work has already been done, reducing the skill level required and improving application accuracy while maintaining low cost.
