Colored Contact Lens Gradient Dot Matrix Speckle Pattern
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for colored contact lenses that can make eyes appear larger and more defined while maintaining a natural appearance, blending seamlessly with the wearer's iris structure and color, without dramatically changing the eye color.
Innovation Solution
The solution involves a colored contact lens design featuring a first print of an annular ring of gradient dot matrix and a second print of an annular ring of speckle pattern, where the speckle pattern comprises clusters of regular or irregular shapes with non-smooth borders, applied concentrically on the lens, enhancing the natural iris appearance by increasing contrast and perceived size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If opaque colored lenses are used to dramatically change eye color, then eye color modification is achieved, but natural appearance is lost
Solution Approach 1:
The lens is divided into multiple functional zones: a central clear zone for natural appearance, an intermediate zone with subtle gradient coloring, and an outer peripheral zone with enhanced contrast patterns. This segmentation allows different regions to serve different purposes - the center maintains natural blending while the periphery provides definition and contrast, resolving the contradiction between dramatic modification and natural appearance.
Solution Approach 2:
Different optical properties are applied to different locations on the lens. The central region uses transparent enhancement colors that allow natural iris to show through, while the peripheral regions use opaque patterns with higher contrast. This local differentiation enables the lens to provide both natural blending in the center and dramatic modification at the edges, satisfying both requirements simultaneously.
2Adaptability or versatility
If transparent enhancement colors are used to maintain natural appearance, then natural blending is achieved, but eye color transformation capability is limited
Solution Approach 1:
The lens merges two traditionally separate lens types into one unified design: transparent enhancement colors in the central zone for natural blending, and opaque colored patterns in the peripheral zone for dramatic transformation. This combination allows the single lens to achieve both natural appearance maintenance and significant eye color transformation, resolving the limitation of transparent lenses alone.
Solution Approach 2:
The design transitions from a single-layer uniform lens to a multi-layer zoned lens with varying opacity and color intensity across different radial distances from the center. This dimensional variation in optical properties enables the lens to provide subtle enhancement near the center while delivering dramatic transformation at the periphery, overcoming the limitation of transparent lenses.
3Manufacturing precision
If opaque patterns are used to define iris structure, then eye definition is improved, but natural blending is reduced
Solution Approach 1:
The opaque patterns are segmented into the peripheral zone only, leaving the central and intermediate zones with transparent or gradient coloring. This spatial segmentation allows the opaque patterns to provide crisp iris definition where needed at the periphery while maintaining natural blending in the central viewing area, resolving the contradiction between definition and blending.
Solution Approach 2:
Opaque patterns with high contrast are applied locally to the outer peripheral region of the lens where they can enhance iris definition without interfering with the natural appearance in the central zone. This localized application of opaque material provides structural definition precisely where it enhances the eye's natural features without compromising overall blending.
