Diagnostic Eyewear for Monovision Preference Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining eye preference for monovision correction, such as bifocal lenses and multifocal contact lenses, often require trial and error, which can be time-consuming and costly, as individuals need to find the optimal eye for near vision correction and strength preference.
Innovation Solution
Diagnostic eyewear systems with interchangeable magnifying and non-magnifying lenses allow users to switch lens positions and try different magnification strengths to determine the preferred eye and strength for near vision correction, facilitating acclimation to monovision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional trial and error methods are used to determine eye preference for monovision correction, then the correct eye and strength can be identified, but the process is time-consuming and costly
Solution Approach 1:
The diagnostic eyewear allows users to perform preliminary testing at home before the actual monovision correction is implemented. Users can try different lens configurations and magnification strengths in advance, determining their eye preference and optimal magnification level without requiring multiple doctor's office visits and trial lenses during the correction process.
2Measurement precision
If multiple pairs of corrective lenses are used to test different configurations, then the optimal monovision setup can be found, but the cost increases significantly
Solution Approach 1:
The diagnostic eyewear serves multiple functions: it can test both eyes for magnification preference, evaluate different magnification strengths, and determine the optimal configuration for monovision correction. This single device replaces the need for multiple specialized trial lenses that would otherwise be required to comprehensively evaluate all possible monovision configurations.
Solution Approach 2:
The system allows users to change the magnification parameter by swapping lenses with different magnification strengths. Users can systematically test various magnification levels to find their optimal preference, and the same eyewear frame can accommodate different lens parameters, making the testing process more cost-effective than purchasing multiple fixed-configuration corrective lenses.
3Productivity
If the doctor quickly determines eye preference during a short office visit, then the process is efficient, but the determination may not be accurate as some people prefer the dominant eye for near vision correction
Solution Approach 1:
The diagnostic eyewear enables users to perform the eye preference determination themselves in a comfortable home environment rather than relying on a doctor's quick assessment during a busy office visit. Users can take their time to thoroughly evaluate different configurations and make informed decisions about their monovision setup without feeling rushed.

AI summary
Diagnostic eyewear systems are disclosed that facilitate the evaluation of and adjustment to monovision as a solution for near vision loss experienced by corrected nearsighted and normal vision persons. The diagnostic eyewear include a magnifying lens and a non-magnifying lens, and a frame that allows the user to switch the locations of the magnifying and non-magnifying lenses from one eye to another. Multiple diagnostic eyewear may be provided as a set, with the magnifying lens of each eyewear having a different magnification power. The diagnostic eyewear may be used to determine magnification eye preference, magnification strength and distance eye preference in order to facilitate acclimation to monovision.
