Vision care instrument

This new type of creation is a vision health care instrument, especially the use of optical principles, with convex lenses and cursor positions to create images of far, near, up, down, left and right, guiding eye movements, allowing eye muscle groups to retract and move. Coordinate the balancing device.

The muscle groups of the eyes, such as rubber bands, maintain the elasticity of the muscle groups by tightening and relaxing. If the tension or relaxation state is maintained for a long time, the eyesight is easily degraded.

When the eye is close to the target, it is necessary to tighten the ciliary muscle to reach the near focal length. If the ciliary muscle loses its elasticity once it relaxes, it will be difficult to tighten the ciliary muscle, that is, the old flower appears in the eye. In the case, if the eye is looking at a distant target, it is necessary to relax the ciliary muscle to adjust the focal length. If the ciliary muscle is tightened for a long time, it is necessary to relax the ciliary muscle but cannot do it, that is, the eye has a nearsightedness.

In order to protect the eyes, it is necessary to let the eyes move to adjust the muscle groups of the eyes. The movements of the eyes are: looking far and near training, eyeball training, in which the near-field training can make the ciliary muscles tighten and relax. Training exercise to maintain the vitality of the ciliary muscle to maintain vision; in addition, eye circumference training can strengthen the training of the extraocular muscles (ie, the six muscles), stimulate the visual nerve to enhance the balance of the brain, and the extraocular muscles Coordination It can smooth the cornea of the eye and improve the astigmatism.

Looking back at the past information, Balliet in US4408846 in 1983, middle-class in the case of CN2060068U in 1990, Deng Qizhuo et al in 1998 CN2289545Y, Gao Hongping in the case of CN2313572Y in 1999, and Horie in the case of US7393102 in 2008 The use of the mechanical axle to move the object back and forth causes the space sense device before and after the image. Because the above device is cumbersome, it is only suitable for being placed on the table, and it is very inconvenient to use.

In 2006, the second CN2770617Y case of Zhang et al. used the left and right rows of cursors to move forward and backward as the front and rear distance changes, and the electrodes on both sides were energized to stimulate the acupuncture points near the eyes. In the 2011 CN201759836U case, Zhang Zai et al. used the left and right two rows of cursors to move forward and backward as the front and rear distance changes, and added the airbags on both sides. The massage head massaged the acupuncture points near the eyes. The above device does not actually understand the specifications of the optical lenses, only It is the movement of the cursor back and forth, can not really accurately create the actual required imaging distance, and does not have the function of guiding the extraocular muscles to be properly trained.

The main purpose of this new creation is to provide a vision health instrument that can display the near-infinity distance imaging effect, and can guide the eyeball to move up, down, left, and right, and provide coordinated operation of the extraocular muscles. A vision care device that allows the various muscles of the eye to obtain a more comprehensive guiding activity.

In order to achieve the purpose of the pre-existing purpose, the novel vision care instrument comprises: an outer casing for isolating external light, and a chamber is formed inside and formed An opening; a second optical lenticular lens assembly is disposed at intervals in the outer casing and is located at an opening of the outer casing; a linear cursor group attached to the outer casing and located in the housing, and the two linear cursor groups respectively cooperate with the two The optical lenticular lens assembly includes a slanted substrate, the slanted substrate is provided with a plurality of spaced and linearly arranged cursors, and a two-ring type cursor set is disposed on the outer casing and located in the chamber, and the two The ring type cursor group is respectively matched with the two optical convex lens assemblies, wherein the ring type cursor group comprises a ring type substrate, the ring type substrate is provided with a plurality of spaced and annularly arranged cursors; and a control unit; The housing is electrically connected to the linear cursor group and the ring cursor group.

According to the above, the linear cursor group in the vision health instrument can be controlled by the control unit to provide a change in the imaging distance, so that the ciliary muscle can be tightened and relaxed, and the ring cursor group can guide the eyeball. The upper, lower, left and right circular movements provide coordinated operation of the extraocular muscles, so that the various muscles of the eyes can be fully guided and active, thereby improving the myopia and astigmatism of the eyes.

Since the linear cursor group 11a (object distance u) moves forward and backward with a small distance, it can display 20 cm to infinity image distance, and the effect of making the eyes look far and near is easy to wear on the head. See Table 1 below for specific implementation information.

In Fig. 5, the convex lens optical center is taken as the origin, when the eye is on the right side, the cursor is on the left side (the object distance is a positive number), and if the image distance is a negative number, the development position and the cursor are located on the left side.

Embodiment 1-2, the optical creation principle of the present invention is as shown in FIG. 5, taking a convex lens with a focal length of 20 cm as an example, and moving the linear cursor group back and forth as shown in FIG. 6, when the linear cursor group 11a (object distance u) is located At 20 cm, the infinity image distance can be displayed; when the linear cursor group 11a (object distance u) is located at 10 cm, the imaging image distance of 20 cm can be displayed. Because the moving distance of the linear cursor group 11a (object distance u) is small, it is close to the eye. The effect is easy to wear on the head. The specific implementation data is shown in Table 2 below.

In Fig. 5, the convex lens optical center is taken as the origin, when the eye is on the right side, the cursor is on the left side (the object distance is a positive number), and if the image distance is a negative number, the development position and the cursor are located on the left side.

Embodiment 1-3, the optical creation principle of the present invention is as shown in FIG. 5, taking a convex lens with a focal length of 5 cm as an example, and moving the linear cursor group back and forth as shown in FIG. 6, when the linear cursor group 11a (object distance) is located at 5 cm. When the infinity image distance is displayed, when the linear cursor group 11a (object distance) is located at 4 cm, the imaging image distance of 20 cm is displayed. Since the linear cursor group 11a (object distance) has a small moving distance before and after, the effect of making the eyes look far and near is achieved, and it is easy to wear on the head. The specific implementation data is shown in Table 3 below.

In Fig. 5, the convex lens optical center is taken as the origin, when the eye is on the right side, the cursor is on the left side (the object distance is a positive number), and if the image distance is a negative number, the development position and the cursor are located on the left side.

Embodiment 2, the novel creation uses the optical principle as shown in FIG. As an example, a convex lens having a focal length of 10 cm is taken as an example. The inside of the lens barrel at a distance of 9.99 cm from the center point of the convex lens is arranged with the cursor around the top, bottom, left and right sides to form a ring type cursor group 11b, as shown in FIG. The development image distance of 9990 cm in front can be displayed. When the cursor of the ring type cursor group 11b flashes in the clockwise direction, the eyeball is guided to move according to its orientation. The eyeball looks at the cursor, and the eyeball can perform coordinated movements of up, down, left, and right to provide the exercise effect of the six muscle groups. The specific implementation data is shown in Table 4 below.

In Fig. 5, the convex lens optical center is taken as the origin, when the eye is on the right side, the cursor is on the left side (the object distance is a positive number), and if the image distance is a negative number, the development position and the cursor are located on the left side.

In summary, the novel creation goes deep into the principle of optical lens, selects the correct convex lens specification and precise cursor distance, shortens the length of the device, and can display the imaging effect from near to infinity distance within a distance of less than 20 cm. And the linear cursor group 11a of the novel creation provides a change of the imaging distance, so that the ciliary muscle reaches the tension and relaxation exercise, and the ring type cursor group 11b can also guide the eyeball to move up and down and left and right, providing six pieces. The coordinated operation of the muscles (upper and inferior rectus muscles, internal and external rectus muscles and superior and inferior oblique muscles) enables more comprehensive guidance and activities of various muscles of the eye, and often uses this new creation for eye care, which can improve myopia. And the problem of astigmatism.
