[b] Dual motor structure: referring to FIG. 3B, when the left power part 223 is a dual motor structure (respectively rotating in forward and reverse directions), it drives the first left gear set 221 and the second left gear set 222, respectively, and The left front yam 211 and the left rear yam 212 are respectively controlled to rotate at the same speed and in the opposite direction on the left central axis A1.

The right power part 323 has the following two application examples: [a] Single motor structure: when the right power part 323 is a single motor structure, a right power bevel gear 324 (see FIG. 3A) is provided; the first right The gear set 321 corresponds to the right power bevel gear 324, and is provided with a first right gear GB11 and a first right bevel gear GB12 coaxially fixed, the first right gear GB11 meshingly connects the right front wedge tooth portion 31A; the first A right bevel gear GB12 meshes with the right power bevel gear 324. The second right gear set 322 corresponds to the right power gear 324, and a second right gear GB21 and a second right bevel gear GB22 coaxially fixed are provided, and the second right gear GB21 meshes to connect the right rear gear 31B; the second right bevel gear GB22 meshes with the right power bevel gear 324.

[b] Dual motor structure: referring to FIG. 3B, when the right power part 323 is a dual motor structure, it drives the first right gear set 321 and the second right gear set 322, respectively, and controls the right front rod 311 And the right rear wheel 312, rotates at the same speed and in the opposite direction on the right central axis A2. The actual application process of this creation is to allow the examinee to wear the device that can perform visual fatigue relaxation. Then, the control unit 40 controls the left and right rear tooth parts 21A and 21B through the left front and right tooth parts 21B, respectively. The left front wheel 211 and the left rear wheel 212 rotate at the same speed and in the opposite direction on the left central axis A1. And the control unit 40 controls the right front 311 and the right rear 312 through the right front tine 31A and the right rear tine 31B, respectively, at the same speed on the right central axis A2 and Turn in the opposite direction. In this way, the line of sight of both eyes will sequentially change from direct vision of both eyes (left eye first viewpoint PA1, right eye first viewpoint PB1 as shown in FIG. 6A) to binocular vision toward the relatively outer side (as shown in FIG. 6B The left eye second viewpoint PA2, the right eye second viewpoint PB2), then return to binocular direct vision (left eye first viewpoint PA1, right eye first viewpoint PB1 as shown in Figure 6C), and then turn into binocular orientation Relatively inside (the third viewpoint PA3 of the left eye and the third viewpoint PB3 of the right eye as shown in FIG. 6D), and finally change back to binocular direct vision (revert to FIG. 6A), this is a visual fatigue relaxation method. That is to say, the usage method of this creation is as follows: 1. The subject performs the first dioptric refraction with a computer refractometer (speedy-i), and records the obtained initial value data. Next, use the visual fatigue relaxation method of rotating shuanghu. 2. After training for 14 minutes using the visual fatigue relaxation method of rotating shuangmian, use a computer refractometer (speedy-i) and record the data of the second dioptric refraction. 3. Re-use the visual fatigue relaxation method of rotating Shuangmianhua. After 14 minutes of training, perform a computerized refractometer (speedy-i) and record the data of the third dioptric refraction. After several experiments, the results of this study were obtained. Ten degrees of ten degrees are used, which is consistent with the expected value of Morgan's rupture point analysis. However, the adjustment power is different according to different ages. The detection of presbyopia (FCC) is used. ) The data is different afterwards. For example, FCC+1.00 adds -1.00ADD+2.00 progressive multifocal lenses to give enhanced adjustment training, younger subjects can use -2.00ADD+4.00 progressive multifocal lenses to give enhanced adjustment training. In more detail, the following methods of use can be carried out by the relevant optometry professionals: 1. Interview (for example: the wearing time of the glasses, the need for vision, previous history of eye diseases, visual problems with the glasses, and whether to use mobile phones (Signs of visual fatigue caused by the computer). 2. Create information (for example: name, birthday, phone, gender, address). 3. Eye visual inspection (for example: eye injury, covering test, near-point test, turning, both eyes in the same direction and double H). 4. The degree of recording (initial degree of computer optometry) is recorded by the computer refractometer before using the rotating prism. 5. Use old eyeglass diopter to find the highest visible optotype (mark the optotype). 6. Use the rotation index to reset to zero first (integrated refractometer index to zero). 7. Gaze at the highest visible visual mark first after external rotation to 15 mm, then internally to 15 mm, and then continue to steadily and slowly outward and inward for a total of 10 times before stopping (rotating 珜鏡 affects the third pair of moving eyes) Sphincter nerve (pupil contraction) ciliary muscle regulation). 8. The subject takes a break (because it is used with the dynamic highest visible sight mark, it will generally be dizzy and the eyes will be uncomfortable). 9. Use a computer refractometer to compare the first record. If the diopter is stable, it means that the visual fatigue has been relaxed. If not, it means that it has not been relaxed. Refer to Table 1 below. (Table I)

10. Return to step 7 and repeat (continue to shrink and adjust) until the diopter is stable. 11. Basic optometry (start optometry after visual fatigue is relaxed, more accurate): use a computer optometry machine to measure the initial power and measure the sharp eye, first enter the pupillary distance (Pupillary Distance, referred to as PD), then the lens is zeroed, and the right eye (OD) starts Starting point, put the cover plate to cover the left eye (OS), red and green test (find the maximum degree of finding the surface), crossed cylindrical mirror (find the best angle and degree of astigmatism), OD first cloud, OS starting point, Put the cover plate to cover the OD, red and green test (find the maximum degree of finding), cross cylindrical mirror (find the best angle and degree of astigmatism), OS first cloud, second binocular cloud, binocular vision balance, Make sure that you can see the 1.0 level visual target clearly, and there will be no uncomfortable state, which is the final vision. Take the subject who used the mobile phone for a long time from 25 to 35 years old as an example. Refer to Figure 8. The first curve L11 represents the right eye before training, and the second curve L12 represents the left eye before training. Experimental data shows that the vision is unstable before training. The third curve L21 represents after right eye training, and the fourth curve L22 represents after left eye training. Experimental data shows that after relaxation training, vision is stable and the effect is very good. The advantages and effects of this creation are as follows: [1] The effect of visual fatigue relaxation training is good. The effect of rotating Shuangmian on the relaxation of the muscles inside and outside the eye, that is, the effect of visual fatigue relaxation on the test diopter change, was verified. Using the eye-adjusting optometry micromotion device (speedy-i) to test the eye adjustment micromotion, the eye adjustment range and load can be obtained. If the recipient has eyes to adjust tightness or to control spasms, use the device that can create visual fatigue and relax movements, and the amount of adjustment stimulation can be obtained by testing with the micro-motion device. Therefore, the effect of visual fatigue relaxation training is good. [2] Pseudomyopia can be alleviated without mydriatic agents. This creation is a physical effect, which uses rotating binoculars to relax the muscles inside and outside the eye to achieve the degree of reducing pseudo-myopia. There is no need to use mydriatic agents during the process, which can reduce the use of drugs. Therefore, without mydriatic agents, pseudomyopia can be alleviated. The above is only a detailed description of the creation through the preferred embodiment. Any simple modifications and changes made to the embodiment will not deviate from the spirit and scope of the creation.
