Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for controlling myopia progression are not sufficiently effective, and there is a need for new solutions that are easy to use and integrate with existing ophthalmic devices, considering the role of circadian light exposure in myopia development.
Innovation Solution
An ophthalmic set that modulates light intensity within specific spectral ranges (360 nm to 520 nm) throughout the day, with higher intensity in the morning and reduced intensity in the evening, using light sources and spectral filtering means to influence choroid thickness and circadian mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional methods (microlenses, atropine, rigid contact lenses) are used to control myopia progression, then some level of myopia control is achieved, but the methods are not efficient enough and require significant user attention or complex compliance
Solution Approach 1:
The ophthalmic set automatically modulates light intensity based on circadian time without requiring user intervention. The control means autonomously adjusts the light source intensity according to the predetermined intraday time-configuration, eliminating the need for manual operation while maintaining effective myopia progression control through consistent circadian-rhythm-aligned light exposure.
2Reliability
If light intensity is continuously high to maximize choroid thickening effect, then myopia progression control is enhanced, but visual comfort and acuity may be compromised during evening hours
Solution Approach 1:
The light source intensity is periodically modulated according to circadian rhythms, with higher intensity during morning hours to promote choroid thickening and myopia control, and reduced intensity during evening hours to preserve visual comfort. This periodic variation aligns with natural circadian cycles, effectively controlling myopia progression while avoiding the harmful effects of continuous high-intensity light exposure.
3Reliability
If spectral filtering means are added to the ophthalmic set to modulate light intensity, then circadian regulation and myopia control are improved, but device complexity increases
Solution Approach 1:
The spectral filtering means are integrated into the existing spectacle lens structure, combining the myopia correction function with the circadian light modulation function in a single unified device. This merging approach allows the ophthalmic set to simultaneously provide refractive correction and circadian-rhythm-aligned light intensity modulation without requiring separate complex systems, thereby reducing overall device complexity while maintaining enhanced myopia control effectiveness.

AI summary
An ophthalmic set for myopia progression control comprises first means suitable for varying an amount of light that has wavelength values comprised in a modulation spectral range and enters an eye (E) of a user. It further comprises control means configured for controlling the first means so that light with wavelength values in the modulation spectral range enters the user's eye with varied intensity during daytime. The first means may comprise light sources (1, 2) and/or spectral filtering means, in particular arranged so as to be fitted on the user's face during appropriate durations. Preferably, light with wavelength values comprised between 360 nm and 520 nm, or between 440 nm and 520 nm, is increased in the morning and reduced in the evening.
