Does vision trainer work?

Vision Training Instrument is through the training of eye internal and external rotation ability to exercise the eye muscles, so that the visual axis of the two eyes constantly moving to train the dominant vision of the three muscles --- ciliary muscle, extraocular muscle, iris muscle, through the synergistic exercise to alleviate the paralytic stiffness of the above muscles, so that it is strong and flexible, so as to improve the regulation of ocular muscles, and ultimately to achieve the object in the retina, clear imaging, and play to restore eyesight. The purpose of a medical device.

1. Improve the sensitivity of the eye's "focus-relaxation" transition. The principle is that myopic patients focusing sensitivity decreases, can cause the eyes to look away from the eye can not be relaxed in time and blurred, the relevant vision training device can enhance the focusing sensitivity of the eyes to achieve the purpose of prevention and treatment of myopia (for example, focusing sensitivity device, linear vision training device or eye muscle training device).

2. Correction of existing refractive errors. By converting the lenses on the comprehensive optometry (bull's-eye), the trainee can be corrected for nearsightedness, farsightedness and astigmatism, so that he or she can see the training target clearly, and provide the basis for optimizing the improvement of visual acuity.

3. Focused hyperopia:

1) Manual focusing hyperopia (e.g., using the "bull's-eye" on the turn knob to add a piece of fog vision), resulting in a certain amount of hyperopia (i.e., fog vision or anterior out-of-focus), offsetting the formation of myopic posterior out-of-focus, and promoting the over-relaxation of intraocular muscles, the lens flattens, which further offsets the nearsightedness and improves the distance vision.

2) Auto zoom farsightedness (e.g., fogging caused by auto farsightedness with auto farsightedness lenses in the Composite Vision Optimization System), which enables auto zoom and gradual increase of farsightedness fogging, and a more pronounced improvement of farsightedness.

4. Adjustment-collecting sensitivity training: The adjustment-collecting tension and relaxation sensitivity training (i.e., crystal manipulation training) can promote the development of myopia of 100-300 degrees in a good direction, and prevent the occurrence and development of myopia.

5. Eyeball sensitivity training: The coordination of visual field limit exercises (i.e., eyeball exercises) can coordinate the function of extraocular muscles after strabismus surgery and expand the visual field, which can help to prevent myopia from developing and establish and improve the function of binocular monocular tertiary vision.

6. Visual cell sensitivity stimulation to promote hyperopia: Using special color light, icon and flash stimulation modes to increase the sensitivity of retinal RGY three visual cells and visual center sensitivity to promote visual development, improve vision and prevent myopia from developing.

7. Binocular monovision training: Provide special flash mode and parallax icon, extraocular muscle coordinated movement, establish and perfect binocular monovision tertiary vision function.

8. High-frequency ear acupuncture point stimulation: Through meridian point stimulation, it can improve the state of eye vision function and prevent myopia from occurring and developing.
