Yellow Filter Illumination System for Eye Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack an effective and non-surgical method to protect healthy eyes, pseudophakic eyes, and eyes with neurodegeneration from short wavelengths of light, particularly those that have undergone cataract surgery or are affected by age-related macular degeneration, as existing solutions often require surgical intervention or are not designed for conventional lighting systems.
Innovation Solution
A conventional illumination device equipped with a yellow filter that absorbs light wavelengths below 500 nm, applied to a conventional lighting system, such as fluorescent, halogen, or incandescent lamps, to provide protection from harmful light rays, thereby compensating for the lack of natural protection in pseudophakic eyes and enhancing protection in healthy eyes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a yellow filter is applied to an illumination system, then protection from short wavelengths (UV and violet/blue light) is improved, but the illumination intensity in the visible spectrum may be reduced
Solution Approach 1:
The patent applies a yellow filter that selectively absorbs only the harmful short wavelengths (UV and violet/blue light below 500 nm) while transmitting the beneficial visible spectrum (500-760 nm). This local quality approach allows the filter to provide targeted protection without compromising overall illumination intensity, as the filter material is designed to have different absorption characteristics for different wavelength ranges.
Solution Approach 2:
The patent changes the spectral transmission parameters of the illumination system by introducing a yellow filter with specific absorption characteristics. The filter is designed to absorb wavelengths below 500 nm while maintaining transmission above 500 nm, thereby modifying the spectral composition of the light to provide therapeutic benefits without significantly reducing visible light intensity.
2Reliability
If surgical intervention (cataract surgery) is performed to remove the crystalline lens, then vision clarity is improved, but natural protection from short wavelengths is lost
Solution Approach 1:
The patent introduces an external yellow filter as an intermediary device that compensates for the loss of natural protection occurring during cataract surgery. The filter acts as a mediator between the illumination source and the eye, providing the protective function that was removed during surgery without requiring re-operation or additional surgical intervention.
Solution Approach 2:
The patent creates a functional copy of the natural crystalline lens protective function using an external yellow filter. Instead of relying on the natural lens (which is removed during surgery), the filter replicates the protective absorption characteristics of the crystalline lens for UV and violet/blue light, thereby copying the protective function without the surgical complexity.
3Adaptability or versatility
If conventional lighting systems are used, then illumination availability is maintained, but protection from harmful wavelengths is insufficient
Solution Approach 1:
The patent makes the conventional illumination system multi-functional by adding a yellow filter that provides both illumination and protection. The same lighting system now serves dual purposes: providing visible light for vision and filtering harmful UV and violet/blue wavelengths, thereby eliminating the need for separate protective devices while maintaining illumination availability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively absorbs harmful violet/blue and ultraviolet light, providing therapeutic and prophylactic protection to eyes without the need for surgical intervention, thereby reducing the risk of vision loss and blindness associated with cataracts and age-related macular degeneration.

AI summary
A device is provided for the treatment and prophylaxis of healthy eyes, pseudoaphakic eyes and/or eyes suffering macular and retinal degeneration that comprises a yellow filter applied to a conventional illumination system to protect them from short wavelengths of the visible spectrum under 500 nm and preferably in the range of 350 nm to 500 nm. This device the difficulties and risks of existing ways of protecting eyes undergoing cataract surgery and prevents or improves the degeneration of healthy eyes and those suffering neurodegeneration by the simple application of a protective filter to any lighting system. Embodiments of the invention comprise combining a conventional light source with a conventional yellow filter that absorbs wavelengths of light shorter than 500 nm so that the filter completely covers the illumination source.
