[0014] (III) Beneficial Effects

[0015] This utility model provides a portable vision training device. It has the following beneficial effects:

[0016] 1. This portable vision training device, through the setting of a rotating component and a display screen, allows the vision training patient to wear the device and observe the test image displayed on the screen through both eyes via the lens frame. This then causes a motor to rotate, with one motor rotating to align the opaque lens frame with the patient's eye. At this time, the nearsighted patient can only observe the content on the screen with one eye. In order to see clearly, the patient needs to continuously contract and relax their muscles, thus achieving a training effect. The eyeballs can then be trained alternately, and the other lenses can also rotate alternately to test the sensitivity of the eyeball to the content on the screen under different lighting conditions. Alternatively, it can be replaced with concave lenses with a certain power, with the power gradually decreasing, to train nearsighted patients to rely on their own eye muscles to see the test content, thus achieving multiple training effects.

[0017] 2. This portable vision training device is equipped with a focusing mechanism that can adjust the focal length according to different eyeballs, enabling personalized training. Moreover, the internal lenses can be replaced with different prescriptions, making it easier for nearsighted patients to see the content displayed on the screen. Attached Figure Description

A semi-circular cover 5 is installed at one end of both the box A2 and the box B4. The semi-circular covers 5 on the upper part of the box A2 and the box B4 are combined to form a cavity structure. Rotating components 6 are installed at both ends of the box A2. The rotating components 6 are located inside the cavity structure. A display screen 7 is installed inside the box B4.

[0027] The strap 1 has a certain degree of elasticity, allowing the patient to wear the device and adapt to various head shapes. The side of the box A2 that fits against the patient's face is smooth and padded. The display screen 7 is controlled by an internal control board and a core processor. A battery is also installed inside the box B4 for convenient portable use by the patient.

[0028] The focusing mechanism 3 includes an inner cylinder 301 and an outer cylinder 302. The outer cylinder 302 is fixed to the inner wall of the box body A2. One end of the inner cylinder 301 is installed inside the outer cylinder 302 and is spirally connected to it. A lens 303 is installed inside the inner cylinder 301. The outer side of the box body A2 has a circular hole corresponding to the inner cylinder 301.

[0029] This spiral design has a large pitch and a certain degree of damping. When the patient rotates the inner cylinder 301, the inner cylinder 301 can move relative to the outer cylinder 302. The lens 303 is a myopia lens and can be changed to different prescriptions.

[0030] The side of box A2 closest to strap 1 has an arc-shaped concave structure, and two guide covers 8 are installed on its arc-shaped concave structure. The two guide covers 8 are respectively installed on two round holes.

[0031] The guide shield 8 is used to contact the patient's eye socket, ensuring a secure fit while providing comfortable use without harming the eyeball.

[0032] A rotating ring 304 is fixedly fitted on the outer end of the inner cylinder 301 away from the outer cylinder 302. The box body A2 is provided with slots 305 that connect the inner and outer sides at the position corresponding to the rotating ring 304. The rotating ring 304 protrudes out of the box body A2 through the slots 305.

[0033] The 304 rotating coil allows the patient to operate it manually, enabling fine-tuning of the focus.

[0034] The rotating assembly 6 includes a motor 601, a flying disc 602, and a mirror frame 603. The motor 601 is fixed inside the housing A2. The flying disc 602 is connected to the output shaft of the motor 601. The mirror frame 603 has a ring structure and multiple frames are provided, which are fixed around the flying disc 602. One of the mirror frames 603 is a closed structure. Both the mirror frame 603 and the mirror frame 603 have light-transmitting sheets 604 installed inside. The light transmittance of the light-transmitting sheets 604 is different. One of the mirror frames 603 is on the same straight line as the inner cylinder 301 and the guide cover 8.

[0035] The closed structure is opaque and is used to cover one of the eyeballs. The light-transmitting sheet 604 is a resin lens, which is black and has varying degrees of transparency.

[0036] The motor 601, the flying disc 602, and the mirror frame 603 are all located inside two closed semi-circular covers 5.

[0037] When in use, after the vision training patient wears the headgear, they align their eyes with the two guide covers 8. The focusing mechanism 3 can adjust the focal length according to different eyeballs, making it easier for the myopic patient to see the content displayed on the screen 7. By observing the test image displayed on the screen 7 through the lens 603, the patient's eyes are directed to rotate the motor 601. One of the motors 601 rotates so that the opaque lens 603 is aligned with the patient's eye. At this time, the myopic patient can only observe the content on the screen 7 with one eye. In order to see clearly, the patient needs to continuously contract and relax their muscles. Then, they can alternate eyeball exercises. The other lens 603 can also rotate alternately to test the sensitivity of the eyeball to the content of the screen 7 under different lighting conditions. Alternatively, a concave mirror with a certain power can be used, with the power gradually decreasing, to train the myopic patient to rely on their own eye muscles to see the test content.
