Description

Technical Field

[0001] The present invention relates to the technical field of vision care equipment, and more particularly to an eye movement guiding device for eye muscle training and a method for using the same. Background Art

[0002] The normal functioning of the eye depends on three types of muscle tissue. The first is the ciliary muscle, which contracts and relaxes to adjust the thickness of the lens, thereby enabling focusing. The second is the extraocular muscles, typically composed of six muscles, responsible for controlling complex movements of the eyeball in directions such as up and down, left and right, and diagonally. The third is the iris muscle (the circular and radial muscle fibers within the iris), which is responsible for regulating the diameter of the pupil.

[0003] Visual function (especially myopia prevention and recovery) is closely related to the coordinated training of eye muscles. In conventional visual activities (such as reading and watching videos), the muscles primarily involved in the movement are limited, making it difficult to achieve comprehensive coordinated stimulation of the eye muscles. This can easily lead to overload of specific muscles and visual fatigue over time.

[0004] Existing traditional eye training devices (such as oscillating LED guides or screen-tracking programs) have significant limitations: their motion guidance patterns are mostly limited to a two-dimensional plane (horizontally or vertically only), making it difficult to effectively simulate the three-dimensional complex motion trajectory of the eyeball in real space. Even simple circular motion guidance lacks effective stimulation of the depth axis. This makes it difficult to fully train the dynamic adjustment function of the ciliary muscle and significantly inadequately train its coordination with the extraocular muscles.

[0005] Based on this, the present invention provides an eye movement guiding device for eye muscle training and a method of using the same. Summary of the Invention

[0006] In order to solve the problems raised in the above-mentioned background technology, the present invention provides an eye movement guiding device for eye muscle training and a method of using the same, which can enable the eyeball to follow the rotation of the sight mark and synchronously activate the ciliary muscle, six extraocular muscles and the choroidal system: the extraocular muscles improve coordination and scanning ability in three-dimensional trajectory movement, breaking the rigidity of flat fixation when using the eyes at close range.

[0056] Specifically, the biomechanical analysis unit analyzes and calculates the real-time contraction force F of the ciliary muscle c based on:

[0057]

[0058] Where ΔC is the change in lens curvature (in diopters), which is obtained by mapping the pupil center displacement. α is the calibration coefficient, is the pupil center coordinate change vector;
