[0032] like Fig. 9 As shown, the method for relieving eye visual fatigue of the present invention is to set a light source corresponding to the position of the eye, so that the light source irradiates the eye from the upper front of the eye at an angle obliquely downward to fill in the eye. The straight-line distance between the light source and the eye is 60-80mm. Preferably 70mm. The light source preferably irradiates the eye downward at an angle of 50-70 degrees, and more preferably irradiates downward at an angle of 60 degrees, that is, the angle between the light incident on the eye (i.e., the line between the center of the light source and the eye) and the longitudinal plane where the eye is located is 30 degrees. The illuminance of the light source is selected based on the ability to fill in the eye so that the eye muscles can see objects in a relaxed state. For ordinary non-blue light, a light-emitting component with an illuminance of 1800-2200 lux can be selected, and the illuminance of the light source is preferably about 2000 lux.

[0033] The device for relieving visual fatigue of the eyes comprises a head card, a lamp arm mounted on the head card, a light source mounted on the lamp arm, and a power supply circuit electrically connected to the light source. The light source irradiates the eyes from above and directly in front of the eyes at an angle tilted downward to provide supplementary light for the eyes. In the device of the present invention, the head card has two functions: one is to install the lamp arm, and the other is to be worn on the head and positioned so that the entire device moves synchronously with the head. Figure 1 The U-shaped header card 1 and Figure 8 The annular adjustable head card 1′ shown. As long as the above two functions can be achieved, the head card can adopt various structures known in the prior art or can be conventionally designed by those skilled in the art. The power supply circuit can be set as needed to facilitate production and use. The shape and size of the lamp arm should enable the light source it carries to be located at the required position for illumination. It is best to be made of a material that can be bent and positioned. According to the differences between different individuals, it can be specifically adjusted so that the light source on the lamp arm is 60-80mm, preferably 70mm, away from the eye in a straight line, and the light source can be tilted downward at an angle of 50-70 degrees to illuminate the eye. It is preferred that the light source be tilted downward at a depression angle of 60 degrees, that is, the angle between the light incident on the eye (i.e., the line between the center of the light source and the eye) and the longitudinal plane where the eye is located is 30 degrees. The above-mentioned limitations on distance and angle in the present invention enable the device of the present invention to achieve the purpose of the invention well without affecting normal eye use. In the present invention, the lamp arm can be one or two. Usually, one is located in the middle and the other two are located on the left and right sides respectively. In the present invention, the light source should be provided with two illuminants, corresponding to the left eye and the right eye respectively. For ordinary non-blue light, a luminous element with an illumination of 1800-2200 lux can be selected as the light source, and the preferred illumination is about 2000 lux.

[0034] Figure 1 , Figure 2 In the illustrated embodiment, the device for relieving visual fatigue of the eyes of the present invention comprises a U-shaped head card 1, a lamp arm 2, a lamp holder 3 as a light source, and a power supply circuit. The U-shaped head card 1 is used to position the device on the head, and a power supply circuit is provided on the top surface of the middle part of the U-shaped head card 1, and the power supply circuit comprises a circuit board 4, a battery 5, and a switch 6. One end of the lamp arm 2 is connected to the U-shaped head card 1, and the other end is connected to the lamp holder 3. The lamp holder comprises a lamp housing 7, a lamp piece 8, and a lamp shade 9. The illuminance of the lamp holder light source is 2000 lux, and the lamp shade 9 is colorless and translucent, and a blue light-proof film is affixed to the surface of the lamp shade 9. The lamp arm 2 is made of a metal hose or a plastic-coated metal hose, which can be bent and positioned at multiple angles, so as to facilitate the adjustment of the position of the lamp holder 3. The inside of the hose can be wrapped with a resin material. An electric wire is inserted into the lamp arm, and the electric wire is electrically connected to the circuit board 4 and the lamp piece 8. The lamp holder 3 can be two, and each is separately provided on the left and right sides, that is, the left light source and the right light source correspond to the left eye and the right eye respectively, and each is connected to the U-shaped head card 1 through the lamp arm 2.

[0035] Figure 3 , Figure 4 , Figure 5 , Figure 6 The embodiment shown is similar to Figure 1 , Figure 2 The embodiment shown is basically the same, except that the light source is in a strip arc-shaped housing 7', and a lamp sheet 8 is provided at each end corresponding to the position of the eyeball. The shape of the lampshade 9' is also strip arc-shaped. Figure 3 , Figure 4 In the illustrated embodiment, both ends of the arc-shaped housing 7 ′ are connected to the U-shaped head clamp 1 through the lamp arms 2 . Figure 5 , Figure 6 In the embodiment shown, the arc-shaped housing 7 ′ is connected to the U-shaped head clamp 1 via a lamp arm 2 in the middle.

[0036] Figure 7 , Figure 8 In the embodiment shown, except for the header card, the basic structure is the same as Figure 1 , Figure 2 The embodiments shown are basically the same. The head clip is an annular adjustable head clip 1′, and a locking mechanism that can tighten the head clip ring to the head is arranged at the position behind the head of the annular adjustable head clip. The locking mechanism includes a symmetrically arranged left tooth member 10 and a right tooth member 11 installed at the rear of the adjustable head clip, and a gear 12 that drives the left tooth member and the right tooth member to shift toward or away from each other and then position. The structure of the left tooth member 10 and the right tooth member 11 is that a bar hole is opened on the arc strip-shaped sheet body and teeth are arranged on one edge of the bar hole. The sheet bodies of the left tooth member and the right tooth member overlap so that the edges with teeth are located on the upper and lower sides respectively. The gear passes through the two bar holes in turn, and when the gear rotates, it can drive the left tooth member and the right tooth member to shift toward or away from each other, so that the annular adjustable head clip 1′ can be reduced or expanded to a head size suitable for different individuals. Stopping the rotation of the gear can position the left tooth member and the right tooth member. The locking mechanism also includes a rack track box 14 for carrying the left and right gears and a track box buckle cover 15 to enclose the left and right gears therein. A tension knob 13 is arranged outside the track box. The tension knob 13 is connected to the gear 12 located in the bar hole through an installation connecting rod 16 and an installation connecting piece 17. Thus, the ring-open adjustable head card 1' can be controlled to shrink or expand by controlling the tension knob 13 and realize positioning on the head.

[0037] Fig. 9As shown, when the device of the present invention is used, the head card 1 is worn on the head, and the switch 6 is turned on, so that the light is irradiated downward from above the brow bone, and the straight-line distance from the eye is 60-80 mm, preferably 70 mm, and the light source enters the eye from the oblique upper side at a depression angle of 50-70 degrees, which does not affect vision and reading, and at the same time makes the pupil photosensitive system sense reasonable brightness, relaxes the pupil and muscles of the eye, can significantly relieve eye fatigue, and prevent and treat pseudomyopia. The present invention is easy to use, can be worn for a long time, and has a significant effect on protecting and restoring the eyes.

[0038] 120 healthy fifth-grade, junior high school and university sophomores with binocular vision below 1.0 were selected as observation subjects, and the students were randomly divided into two groups, A and B, with 60 students in each group. Group A wore the device of the present invention when they needed to study indoors every day, and Group B was the control group, which did not wear the supplementary light for eyes at any time. The binocular vision and the persistence of clear vision of the students in Group A and Group B were measured before the first class and after the fourth class every day, that is, the daily visual function changes of the students in Group A and Group B.

[0039] The results of the study showed that the binocular vision and visual persistence of the students wearing the device of the present invention did not change significantly in one day, while the control group had a significant decrease in vision at the end of the day's class (p<0.02). In addition, through a one-month follow-up survey, the myopia of the students in Group A wearing the device of the present invention was greatly reduced, from the average naked eye vision of 0.6 before the test to 0.8, while the average naked eye vision of Group B decreased from 0.6 to 0.5. By comparison, the method and special device of the present invention can effectively prevent eye muscle fatigue, thereby protecting the eyes, and have a significant effect on various blurred vision caused by pseudomyopia and eye muscle fatigue.
