DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] The purpose of the utility model is to provide a projection device for exercising eye muscles, which guides the eye to rotate by moving the position of the light spot, thereby exercising the relevant muscle groups, allowing the muscle groups that have been used for a long time to rest and the muscle groups that have not been fully used to be exercised.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0035] Reference Figures 1 to 8 This embodiment provides a projection device 100 for exercising eye muscles, including a level adjustment platform 1, a rotating frame, a first motor, a projection light source 4, a second motor and a level 5.

[0036] The leveling platform 1 includes a base, a table 11, and a handle, and the angle of the table 11 can be adjusted by the handle. The rotating frame rotates around a first axis, which is perpendicular to the table 11. The first motor is used to drive the rotating frame to rotate around the first axis, and the first motor is mounted on the table 11. The projection light source 4 rotates around a second axis, which is perpendicular to the first axis, and the projection light source 4 is used to project the light spot 8. The second motor is used to drive the projection light source 4 to rotate around the second axis, and the second motor is mounted on the rotating frame. The level 5 is mounted on the top of the projection light source 4, and the level 5 is used to provide a reference for the adjustment operation of the leveling platform 1.

[0037] The working principle of the projection device 100 for training eye muscles in this embodiment is as follows:

[0038] Projection light source 4 projects a light spot 8 onto a projection surface 7, such as a wall or screen. The first motor rotates to adjust the horizontal position of light spot 8, while the second motor rotates to adjust the vertical position of light spot 8. Adjusting the position of light spot 8 guides eye movement, thereby exercising specific muscle groups and preventing relaxation of other muscle groups. This prevents fatigue and damage caused by prolonged use of a limited number of muscle groups, thereby preventing myopia.

[0039] Before use, the leveling platform 1 is operated by referring to the level 5 to adjust the angle of the table 11 of the leveling platform 1 until the level 5 shows level. At this time, the first axis is vertical and the second axis is horizontal.

[0040] As a possible example, in this embodiment, the projection light source 4 is a low color temperature (2700K~3000K) light source, which contains a large amount of deep red light and near-infrared light, and a small amount of blue light that is harmful to the human eye, thereby effectively inhibiting excessive growth of the eye axis.

[0041] As a possible example, in this embodiment, a first housing 2 is fixed on the table 11, and the first motor is installed in the first housing 2. The first housing 2 plays a role of dustproof and waterproof, and protects the first motor inside.

[0042] As a possible example, in this embodiment, the turret includes a U-shaped frame and a first rotating shaft. The U-shaped frame has an opening facing upward. The first rotating shaft is fixed to the center of the U-shaped frame and is rotatably connected to the first housing 2. The lower end of the first rotating shaft is located within the first housing 2, and the projection light source 4 is located within the opening of the U-shaped frame. This turret is both symmetrical and has an opening for accommodating the projection light source 4. The overall structure is simple and easy to install. Those skilled in the art may also select a turret with other shapes based on actual needs.

[0043] As a possible example, in this embodiment, a second housing 3 is fixed to one end of the U-shaped frame, within which the second motor is mounted. A counterweight is fixed to the other end of the U-shaped frame. The second housing 3 provides dust and water protection, protecting the second motor within. The counterweight balances the forces at both ends of the U-shaped frame, thereby improving structural stability.

[0044] As a possible example, in this embodiment, a second rotating shaft and a third rotating shaft are respectively fixed to the left and right ends of the projection light source 4. The second rotating shaft is rotationally connected to the second housing 3, and the third rotating shaft is rotationally connected to the counterweight. The second motor is used to drive the second rotating shaft to rotate. However, actual embodiments are not limited to this. For example, the third rotating shaft may also be rotationally connected to the projection light source 4.

[0045] As a possible example, in this embodiment, a focusing lens 6 is connected to the front end of the projection light source 4 to adjust the size of the light spot 8. It should be noted that in actual use, the distance between the display position of the light spot 8 and the projection light source 4 varies depending on the scene. By focusing the light spot 8, the size and brightness of the light spot 8 can be adjusted to meet actual usage requirements.

[0046] As a possible example, in this embodiment, the projection device 100 for eye muscle training further includes a screen for displaying the light spot 8. It should be noted that some usage scenarios may not provide a flat wall (e.g., in a rural environment), which may affect the presentation of the light spot 8. By providing a portable screen, this embodiment enables the projection device 100 for eye muscle training to have a wider range of usage scenarios and achieve better results.

[0047] As a possible example, in this embodiment, the projection device 100 for exercising eye muscles further includes a control unit. The control unit is electrically connected to the first motor and the second motor, respectively, to control the operation of the first motor and the second motor. The first housing 2 is provided with a first communication interface, and the second housing 3 is provided with a second communication interface. The first communication interface and the second communication interface are used to connect circuits to achieve electrical connection between the first motor and the control unit, and the second motor and the control unit. It is understood that the first motor and the second motor can also be controlled independently.

[0048] As a possible example, in this embodiment, the projection device 100 for exercising eye muscles further includes a remote controller, which is wirelessly connected to the control unit to send control instructions to the control unit. In addition, those skilled in the art may also use other types of control instruction input methods such as an operation panel.

[0049] Reference Figures 3 to 8 This embodiment also provides a method for preventing myopia, using the projection device 100 for training eye muscles, including the following steps:

[0050] Step 1: Exercise the medial and lateral rectus muscles:

[0051] Reference Figure 3 , so that the light spot 8 flickers in sequence at the 3 o'clock and 9 o'clock positions, and the eyes follow the movement of the light spot 8, and the cycle repeats several times (for example, 10 times).

[0052] Step 2: Exercise the superior and inferior rectus muscles:

[0053] Reference Figure 4 , make the light spot 8 flicker in the 3 o'clock, 6 o'clock, 9 o'clock and 12 o'clock directions in the order of 12 o'clock → 6 o'clock → 3 o'clock → 9 o'clock, and the eyes follow the movement of the light spot 8 for several times (for example, 10 times).

[0054] Afterwards, refer to Figure 5 , so that the light spot 8 flickers again in the order of 12 o'clock → 6 o'clock → 9 o'clock → 3 o'clock, and the eyes follow the rotation of the light spot 8, and the cycle repeats several times (for example, 10 times).

[0055] In actual operation, you can also first Figure 5 Follow the exercise steps shown, then Figure 4 Exercise steps shown.

[0056] Step 3: Exercise the superior and inferior oblique muscles:

[0057] Reference Figure 6 , make the light spot 8 flicker in the directions of 2 o'clock, 4 o'clock, 8 o'clock, and 10 o'clock in the order of 2 o'clock → 10 o'clock → 8 o'clock → 4 o'clock, and the eyes follow the movement of the light spot 8 for several times (for example, 10 times).

[0058] Afterwards, refer to Figure 7 , so that the light spot 8 flickers again in the order of 2 o'clock → 4 o'clock → 8 o'clock → 10 o'clock, and the eyes follow the movement of the light spot 8, and the cycle repeats several times (for example, 10 times).

[0059] In actual operation, you can also first Figure 7 Follow the exercise steps shown, then Figure 6 Exercise steps shown.

[0060] Step 4: Exercise the extraocular muscles:

[0061] Reference Figure 8 , make the light spot 8 move in the direction of 12 o'clock → 8 o'clock → 4 o'clock → 10 o'clock → 6 o'clock → 2 o'clock → 9 o'clock → 5 o'clock → 1 o'clock → 7 o'clock → 11 o'clock → 3 o'clock, and the eyes follow the movement of the light spot 8, and repeat several times (for example, 5 times).

[0062] For example, the light spot 8 may stay at each position for 1.2 seconds. Those skilled in the art may also choose other time settings, such as 1.5 seconds.

[0063] The distance between the projection light source 4 and the projection surface 7 (e.g., a screen or wall) is generally 1 to 3 meters. After powering on the projector, the focus lens 6 should be adjusted to minimize the size of the light spot 8. Then, using the level 5, adjust the surface 11 of the leveling table 1 to a horizontal position. The human eye exercises its eye muscles at a distance of 72 to 4 meters from the projection surface.

[0064] The eyes follow the light spot 8 and rotate. Through four training steps, the ciliary muscle, rectus eye muscle, oblique eye muscle and extraocular muscle can be trained respectively, so as to achieve the purpose of preventing myopia.

[0065] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
