Display Image Blur Control Using Ciliary Muscle Tension

The patent applies the dynamics principle by making the image blurriness dynamic rather than static. The system continuously adjusts the degree of image blurriness based on real-time detection of ciliary muscle tension signals. When muscle tension increases, the system increases image blurriness to stimulate accommodation; when tension decreases, it reduces blurriness to maintain readability. This dynamic adjustment ensures the ciliary muscles remain active and mobile while the user views the display, preventing muscle atrophy and myopia development.

The patent applies the local quality principle by differentiating the treatment of different visual elements on the display. The system selectively applies varying degrees of blurriness to different regions or elements based on their importance and the user's accommodation state. Critical information remains sharp and clear, while less important background or peripheral elements are blurred to stimulate ciliary muscle activity. This localized differentiation maintains both image clarity for essential content and muscle mobility stimulation simultaneously.

The patent applies the mechanics substitution principle by replacing complex mechanical or invasive measurement systems with a more sophisticated signal processing approach. Instead of using physical sensors that directly contact or mechanically measure ciliary muscle tension, the system uses optical or electromagnetic sensing methods combined with advanced signal processing algorithms to detect muscle tension indicators. This substitution reduces mechanical complexity while maintaining the adaptability to dynamically adjust image blurriness based on real-time muscle state.
