Wearable Irradiation Device for Myopia Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for preventing myopia and slowing its progression, such as sunglasses and UV-blocking glass, primarily focus on intercepting harmful UVB and UVC rays but lack specificity in wavelength ranges effective for eye health, and there is a lack of clear understanding on the effective wavelength range for preventing myopia.
Innovation Solution
A wearable irradiation device with a light source emitting light within the 350 to 400 nm wavelength range, positioned 0 to 100 mm from the eyeball, to effectively irradiate the eyeball and prevent myopia progression, which may also include additional wavelengths like 440 to 480 nm, red, near infrared, and far infrared, or white light.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If UV-blocking materials (sunglasses, contact lenses, glass) are used to intercept harmful UVB and UVC rays, then eye protection from harmful radiation is improved, but the ability to prevent myopia progression is not effectively achieved
Solution Approach 1:
The patent changes the wavelength parameter from blocking UVB/UVC (315 nm or less) to transmitting violet light (380-400 nm). This parameter change transforms the function from purely protective to therapeutically effective for myopia prevention, resolving the contradiction by selecting a specific wavelength range that provides both protection and therapeutic benefit
2Object-affected harmful factors
If broad-spectrum sunlight is blocked to protect eyes from harm, then harmful radiation exposure is reduced, but the specific wavelength range effective for preventing myopia is not utilized
Solution Approach 1:
The patent applies local quality by selectively transmitting only the violet light wavelength range (380-400 nm) while blocking other wavelengths. This creates a localized spectral quality that is specifically effective for myopia prevention, rather than using broad-spectrum blocking, thus resolving the contradiction between protection and effectiveness

AI summary
To provide an irradiation device capable of preventing myopia or slowing the progression of myopia by the action of light irradiated toward the eyeball. An irradiation device (10) comprises a light source (1) and an instrument (2) on which the light source (1) is mounted. The light source (1) emits at least light having a wavelength within a range of 350 to 400 nm, inclusive, and is disposed in a position that allows irradiation in an eyeball direction when the instrument (2) is mounted. Further, the light source (1) is disposed in a position 0 to 100 mm, inclusive, from a surface of the eyeball. At this time, an irradiance of the light having a wavelength within the range of 350 to 400 nm, inclusive, is 0.02 to 1.0 W/m2, inclusive, on the eyeball surface when the instrument (2) is worn.
