Solution Overview

Problem

Current treatments for preventing or slowing the progression of myopia, such as orthokeratology and peripheral defocus lenses, are not effective and have significant side effects, while atropine ophthalmic drops have uncertain long-term effectiveness, highlighting a need for a novel approach to mitigate myopia progression.

Innovation Solution

A lens unit with a spectral selective retinal stimulation modulation, configured to increase the blue light component reaching the eye through a spectral coder pattern on the lens, which induces low-frequency temporal changes in light exposure to slow eye elongation and mitigate myopia progression.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If orthokeratology or peripheral defocus lenses are used, then myopia progression may be slowed, but the treatments produce mixed results and have significant side effects

Engineering Contradiction:

Improveeffectiveness of myopia preventionVSAvoidside effects of treatment

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the spectral parameters of light by incorporating a spectral selective pattern that transmits specific wavelengths (particularly blue light around 450-480nm) while blocking others. This transforms ordinary light into therapeutically optimized light that stimulates retinal photoreceptors to trigger emmetropization, achieving myopia prevention without the side effects of contact lenses or pharmacologic agents

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent replaces mechanical/optical systems (contact lenses, glasses) with a photobiological system. Instead of using physical lens curvature changes or optical power distribution modifications, the invention uses wavelength-selective photostimulation of retinal cells to naturally regulate eye growth through the body's own emmetropization mechanism

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If atropine ophthalmic drops are used, then myopia progression may be slowed, but long-term effectiveness is uncertain

Engineering Contradiction:

Improvelong-term effectivenessVSAvoidduration of treatment uncertainty

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent enables the eye's self-regulation mechanism (emmetropization) to work naturally by providing appropriate spectral stimulation. The retinal photoreceptors detect the wavelength-specific light pattern and automatically trigger neurobiological responses that regulate eye growth, eliminating the need for external pharmacologic intervention and its associated long-term uncertainty

Inventive Principle:

Principle #25Self-service

3Reliability

If blue light component is increased to prevent myopia, then emmetropization is promoted, but excessive blue light may cause retinal damage

Engineering Contradiction:

Improveemmetropization effectivenessVSAvoidretinal damage from blue light

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by creating a spectral selective pattern with specific spatial distribution. The pattern includes alternating regions of high and low transmission at specific wavelengths, with particular emphasis on transmitting blue light in certain spatial zones while blocking it in others. This localized spectral modulation provides therapeutic blue light stimulation without overwhelming the retina with excessive energy

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent uses periodic action through its spatially periodic transmission pattern. The spectral selective pattern consists of repeating units of high-transmission and low-transmission regions at specific wavelengths. As light passes through this periodic structure, it creates a modulated spectral signal that stimulates retinal photoreceptors rhythmically, promoting emmetropization while avoiding continuous excessive blue light exposure

Inventive Principle:

Principle #19Periodic action

AI summary

The present invention relates to a novel lens unit being configured for spectral selective retinal stimulation modulation, which is advantageously a passive modulation effect in the lens of the invention. More specifically, the lens unit comprises a lens substrate having a certain volume defining a front and back surface, wherein the lens unit carries a spectral coder which, when the lens unit is in use, operates as a temporal spectral coder with respect to a portion of input light interacting with the lens unit and reaching the eye.
