Solution Overview
Problem
The increasing prevalence of myopia worldwide, particularly axial myopia, which leads to irreversible elongation of the eye's axial length and potential blindness, necessitates effective prevention and treatment methods.
Innovation Solution
Exposure to light with a wavelength range of 350 nm to 400 nm, utilizing devices such as light transmission parts in eyeglasses and light emission parts in lighting equipment, to suppress the occurrence and progression of myopia by transmitting or emitting violet light within this range, thereby reducing the axial length elongation and refractive values of the eye.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If light with wavelength 400 nm or less is transmitted to the eye, then myopia prevention effect is achieved, but eye damage from ultraviolet light occurs
Solution Approach 1:
The patent applies local quality by selectively transmitting specific wavelength ranges (350-400 nm) while blocking other wavelengths. The light transmission part is designed to have different transmission characteristics for different wavelength ranges, allowing beneficial violet light to pass through while blocking harmful ultraviolet light below 350 nm.
Solution Approach 2:
The patent changes the wavelength parameter of transmitted light to resolve the contradiction. By specifying that only light in the 350-400 nm range should be transmitted (rather than all light below 400 nm), the patent achieves myopia prevention while avoiding eye damage from shorter wavelength ultraviolet light.
2Ease of operation
If conventional eyeglasses transmit all visible light, then good vision is achieved, but myopia progression occurs due to lack of violet light
Solution Approach 1:
The patent modifies the light transmission characteristics of eyeglasses by introducing selective wavelength transmission. The light transmission part is designed to specifically transmit violet light (350-400 nm) while maintaining transmission of beneficial visible light, creating a localized spectral modification that addresses myopia progression without compromising overall vision quality.
3Reliability
If light transmission part transmits violet light (360-400 nm), then myopia treatment effect is achieved, but excessive irradiance may cause eye damage
Solution Approach 1:
The patent controls the irradiance parameter of transmitted violet light to resolve the contradiction. By specifying that irradiance should be 1.0 mW/cm² or less, the patent ensures sufficient light intensity for myopia treatment while preventing eye damage from excessive irradiance.
