Optical System for Myopia Treatment via Selective Wavelength Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current optical systems fail to effectively protect eyes from harmful natural light while maintaining the benefits of light stimulation for myopia progression and hormonal regulation, as they either block beneficial wavelengths or allow harmful UV and blue light to pass through.
Innovation Solution
An optical system that combines red filtering with blue-green light exposure, using a spectral transmission profile that selectively transmits light in the 460-530 nm range to enhance hormonal regulation and minimize myopia progression, incorporating luminescent agents and a controller device to adjust light emission based on ambient conditions and wearer data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If solar lenses block harmful UV and blue light, then eye protection from harmful light is improved, but the benefits of outdoor activities on myopia progression are decreased
Solution Approach 1:
The optical system applies different optical properties to different wavelength ranges: it blocks harmful UV and blue light (380-490nm) while transmitting beneficial green light (490-530nm). This localized wavelength-specific filtering resolves the contradiction by allowing selective protection that preserves beneficial light effects.
Solution Approach 2:
The system changes the transmission parameters of light based on wavelength, using a spectral transmission profile that varies transmittance across different wavelengths. This allows the system to block harmful wavelengths while transmitting beneficial wavelengths, resolving the contradiction between protection and benefit preservation.
2Object-affected harmful factors
If optical systems block all harmful light wavelengths, then eye protection is improved, but hormonal regulation benefits are reduced
Solution Approach 1:
The optical system selectively filters light based on wavelength, blocking harmful UV and blue light while transmitting beneficial green light that stimulates dopamine production. This localized wavelength selection resolves the contradiction by protecting from harm while preserving hormonal regulation benefits.
Solution Approach 2:
The system converts the harmful effect of broad-spectrum light blocking into a beneficial selective filtering approach, where the very property of wavelength-dependent filtering that protects from harm also enables transmission of the specific wavelengths needed for dopamine production and hormonal regulation.
3Productivity
If optical systems transmit all visible light, then light stimulation benefits are improved, but harmful UV and blue light exposure increases
Solution Approach 1:
Rather than uniformly transmitting all visible light, the system applies local quality control by wavelength, transmitting only the beneficial green light portion (490-530nm) while blocking harmful UV and blue light. This resolves the contradiction by providing selective transmission that preserves benefits while eliminating harm.
Solution Approach 2:
The system changes the transmission parameter from uniform across all wavelengths to wavelength-dependent, using a spectral transmission profile that selectively transmits beneficial wavelengths while blocking harmful ones, thus resolving the contradiction between light stimulation benefits and harmful exposure.
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 system effectively reduces myopia progression by optimizing light-induced hormonal regulation, enhancing retinal exposure to beneficial blue-green light while blocking harmful wavelengths, thus providing protection and improving visual acuity.
Implementation Method 1
Dopamine seems to be implied in the progression of the eye length, and thus implied in myopia progression. Low concentrations of retinal dopamine were shown to be associated with form deprivation myopia. Refractive development is associated with illuminance dependent dopamine release.
Implementation Method 2
Solar lenses protect the eyes from the harmful effects of natural light but also appear to decrease the benefits of the outdoor activities on the myopia progression.
Implementation Method 3
incorporating luminescent agents and a controller device to adjust light emission based on ambient conditions and wearer data
