Contact Lens Limbal Ring Halo Effect Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current contact lenses that enhance eye appearance often introduce unnatural elements, making it challenging to create lenses that make eyes appear larger, more colored, or more youthful while maintaining a natural appearance.
Innovation Solution
The design of contact lenses featuring a central portion, an iris portion, a limbal ring, and a peripheral portion, where the limbal ring's inner diameter is greater than the outer diameter of the iris portion, creating a halo effect by an effect band with different color or textural characteristics that blends with the natural iris and sclera, enhancing the eye's appearance without an unnatural look.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If contact lenses are colored or tinted to enhance eye appearance, then the eye can appear larger, more colored, or more youthful, but the appearance becomes unnatural
Solution Approach 1:
The patent applies different color and transparency characteristics to different zones of the contact lens. The iris portion has colored or tinted patterns to enhance iris appearance, while the limbal ring has distinct color characteristics to create a natural transition zone. This localized differentiation allows the lens to enhance specific eye features while maintaining natural overall appearance.
Solution Approach 2:
The contact lens is divided into distinct functional zones: a central portion, an iris portion with colored patterns, a limbal ring with different color characteristics, and a peripheral portion. This segmentation allows each zone to serve its specific purpose in enhancing eye appearance naturally, with the limbal ring specifically designed to create a halo effect that blends with natural anatomy.
2Shape
If the limbal ring inner diameter is greater than the outer diameter of the iris portion, then a halo effect is created, but the lens design becomes more complex
Solution Approach 1:
The patent utilizes color and transparency variations to create the halo effect. The limbal ring is designed with specific color and transparency characteristics that differ from both the iris portion and the peripheral portion. This color differentiation creates the visual halo effect at the interface between the iris and sclera, achieving the desired aesthetic without requiring complex mechanical structures.

AI summary
A contact lens with a central portion, an iris portion, and a peripheral portion disposed about the iris portion; an effect band in or just outside the iris portion helps to provide the lens with a halo effect when worn on eye.
