Optical Device for Eyesight Restoration Using Minifying Lens Array
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Near-sightedness develops due to the crystalline lens thickening when focusing on close objects, and corrective eyewear with concave lenses further deteriorates the lens's ability to return to its original state, leading to blurred and enlarged images.
Innovation Solution
An optical device comprising a first convex lens and four concave lenses, with a unique tube configuration allowing the second and third tubes to move within the first tube, and a fixing unit to cover the second tube, enabling the user to see objects as smaller and farther away, using a scale for adjustment and caps for training purposes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If corrective eyewear with concave lenses is worn to compensate for near-sightedness, then the ability to see objects clearly is improved, but the crystalline lens's ability to return to its original state deteriorates and the lens hardens in the thickened state
Solution Approach 1:
Instead of using concave lenses to correct near-sightedness (conventional approach), this invention uses a convex lens combined with concave lenses to create an inverted optical effect. The convex lens (f=100mm) combined with concave lenses (f=-50mm, f=-25mm, f=-20mm, f=-20mm) produces a minifying effect that makes objects appear smaller and farther away, which is the opposite of how traditional corrective lenses work. This inverted approach helps the crystalline lens return to its original state by reducing the demand for continuous thickening.
Solution Approach 2:
The invention changes the optical parameters by using a specific combination of lens focal lengths (convex f=100mm with concave f=-50mm, -25mm, -20mm, -20mm) to achieve a 1/8 size reduction effect. This parameter change allows objects to be viewed in a way that promotes crystalline lens recovery, transforming the viewing experience from enlarged/blurred to minimized/clear.
2Measurement precision
If the crystalline lens thickens to focus on close objects, then the ability to see close objects is improved, but the image becomes large and blurry
Solution Approach 1:
The invention inverts the traditional approach to close object vision. Instead of allowing the crystalline lens to thicken and produce large, blurry images, the optical device uses a convex lens with multiple concave lenses to create a minifying effect. This makes close objects appear smaller and farther away, preventing the crystalline lens from excessive thickening while maintaining clear vision.
Solution Approach 2:
The invention segments the correction function into multiple lens components rather than relying solely on the crystalline lens thickening. The system divides the optical correction into a convex lens (f=100mm) and four concave lenses (f=-50mm, -25mm, -20mm, -20mm) arranged in tubes, with the second and third tubes movable within the first tube. This segmentation allows precise control over the optical effect while protecting the natural lens.
3Measurement precision
If traditional corrective lenses are used, then vision is corrected, but the device complexity increases due to multiple lenses and adjustable mechanisms
Solution Approach 1:
The invention applies the nesting principle by placing the second tube (containing first and second concave lenses) inside the first tube (containing convex lens), and the third tube (containing third and fourth concave lenses) inside the second tube. The fourth tube covers the second tube. This nested structure organizes multiple lenses and adjustment mechanisms in a compact, integrated form that reduces overall device complexity while maintaining the sophisticated optical correction capabilities.
