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.

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

Engineering Contradiction:

Core Design Contradiction:
Object-affected harmful factorsVSProductivity

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.

Inventive Principle:
Principle #3Local quality

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.

Inventive Principle:
Principle #35Parameter changes

2Object-affected harmful factors

If optical systems block all harmful light wavelengths, then eye protection is improved, but hormonal regulation benefits are reduced

Engineering Contradiction:
Improveeye protectionVSAvoidhormonal regulation
Core Design Contradiction:
Object-affected harmful factorsVSReliability

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.

Inventive Principle:
Principle #3Local quality

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.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

3Productivity

If optical systems transmit all visible light, then light stimulation benefits are improved, but harmful UV and blue light exposure increases

Engineering Contradiction:
Improvemyopia progression benefitVSAvoidharmful light exposure
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

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.

Inventive Principle:
Principle #3Local quality

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.

Scientific EffectPhototransduction: Photoelectric Effect

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.
