Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of myopia prevention and control, and particularly relates to a multifunctional vision prevention and control wearable device based on sound wave factors and a use method. BACKGROUND

[0002] The current development status of myopia prevention and control technology is as follows:

[0003] 1. Limitations of existing vision prevention and control technology:

[0004] (1) The single nature and compliance problem of traditional therapy. The current mainstream vision prevention and control means (such as light therapy, physical training, etc.) have problems such as boring treatment process and low compliance. For example, simple light therapy improves choroidal microcirculation through red light stimulation, but lacks interest and is difficult to adhere to for a long time.

[0005] (2) Limitations of invasive vision prevention and control devices: Some vision prevention and control wearable devices (such as contact lens sensors or intraocular injection therapy) may cause discomfort or complications, and it is difficult to achieve daily application.

[0006] 2. Medical application basis of sound wave therapy:

[0007] (1) The regulating effect of sound waves on the nervous system. Sound wave factor intervention therapy has been proven to improve visual function by regulating brain waves, relieving anxiety, and promoting neural excitability. For example, music electrotherapy can treat neuralgia and insomnia through synchronous sound wave and electric current stimulation, providing a physiological basis for the application of sound waves in vision prevention and control.

[0008] (2) Innovative exploration of sound-light combined therapy. Recent clinical medical verification shows that combining sound waves (such as specific frequency sound wave factors) with light can enhance the treatment effect. By synchronously activating the visual neural pathway through multi-sensory stimulation, the visual function of patients with amblyopia and myopia is improved.

[0009] 3. Based on the generation of vibration waves by sound wave factors, a series of biological effects on biological cells and tissues around the acupoints of the human eye are produced for vision prevention and control. The core principle of "sound wave phonon myopia prevention and control" is based on the physical properties and biological effects of sound waves, combined with the resonance effect of phonons (lattice vibration energy quantum), to improve eye microcirculation, regulate cell activity, and inhibit the development of myopia.

[0010] 4. Mechanical effect of acoustic waves and microcirculation improvement + resonance effect and cell activity regulation principle: Acoustic wave factors produce vibration waves (such as 30-100 Hz) through mechanical vibration, which can promote eye tissue microcirculation, increase choroidal blood flow velocity, provide more oxygen and nutrients for the retina and sclera, and relieve visual fatigue. The propagation of acoustic phonons (low-frequency phonons) can enhance the ion migration inside and outside the cells, form electrical signal stimulation, further regulate vascular smooth muscle tension, and improve blood circulation. At the same time, acoustic wave factors of specific frequency can resonate with Na+, K+ ions of eye cells, activate mitochondrial activity, promote ATP synthesis, and enhance cell metabolic capacity. This resonance effect can repair damaged cells and delay myopia progression.

[0011] 5. Application mechanism of acoustic wave factors as a non-invasive physical intervention means in vision prevention and control involves biomechanics, neural regulation, and molecular level effects, and the core mechanism is as follows:

[0012] (1) Biomechanical effect: Acoustic waves act on eye tissue through mechanical vibration, producing micro-rheological effect. Pulsed acoustic waves of specific frequency (40-80 Hz) can promote aqueous humor circulation dynamics, reducing intraocular pressure by 10%-15% and relieving optic nerve compression caused by high intraocular pressure. At the same time, acoustic shear force can enhance choroidal blood flow velocity (by 20%-30%), improve retinal blood oxygen supply, and inhibit excessive elongation of axons.

[0013] (2) Ciliary muscle regulation mechanism: Frequency-modulated acoustic waves (10-30 Hz) target regulate ciliary muscle motor units through resonance effect. Clinical data show that 15 minutes of daily intervention can reduce accommodation lag by 0.25-0.5D, significantly improving accommodation sensitivity. This effect is due to changes in myosin light chain phosphorylation levels induced by acoustic waves, regulating smooth muscle contraction-relaxation rhythm.

[0014] (3) Retinal neural plasticity regulation: Acoustic stimulation activates visual cortex alpha band (8-12 Hz) oscillation through bone conduction, enhancing neuronal synchronicity. FMRI studies have confirmed that the primary visual cortex BOLD signal response rate increased by 18% after intervention, promoting visual signal processing efficiency. At the same time, it regulates the dopaminergic signaling pathway, increasing retinal DA release by 30% and inhibiting the expression of key factors MMP-2 for eye axis growth.

[0015] (4) Molecular level mechanism: Acoustic mechanical transduction activates ERK1 / 2 signals through integrin-FAK pathway, upregulates antioxidant enzyme SOD2 expression (2.3 times), and reduces corneal oxidative stress level. At the same time, it regulates the expression pattern of myopia-related genes (such as EGR1, FOS), and inhibits the scleral remodeling process.

[0016] In summary, existing clinical studies show that complex frequency sound wave intervention can reduce the annual growth rate of myopia in adolescents by 35%-50%. However, the parameters of the individualized program need to be optimized, and the long-term effects and mechanism correlation still need further study. This technology provides a new way for physical vision intervention and has important transformation value. SUMMARY
