AI Technical Summary
When the visual function inspection device is bound for a long time, it is easy to cause fatigue and damage to the eyes, and the equipment is too closed to the surroundings of the eyes, resulting in the inability to breathe, which will cause secondary damage to the skin around the eyes after a long period of training.
A visual function inspection and training device is designed, using a viscoelastic damper as a protective mechanism to buffer the wearer's eye pressure, and micro-heat the surroundings of the eyes through heating plates and breathable holes to promote blood flow and improve the accuracy of vision examination. At the same time, a gas cylinder is set to discharge overheated heat flow to prevent the eyes from overheating.
Through the buffering effect of the viscoelastic damper, the damage to the eyes of the strap is avoided by being too tight, and the blood is activated by micro-heating, which improves the accuracy of vision examination, while preventing eyes from overheating and protecting eye health.

Technical Field
[0001] The utility model relates to the technical field of visual function detection and training rehabilitation, in particular to visual function detection and training equipment. Background Art
[0002] Visual function test equipment is a common ophthalmic examination equipment used to observe the fine structures of the anterior segment of the eye, such as the cornea, conjunctiva and iris, to check for inflammation, foreign matter or other abnormalities. It is also used to examine the fundus, that is, the retina, optic nerve, blood vessels and other structures at the back of the eyeball to evaluate whether there are fundus lesions. Visual training is to exercise the eye muscles by training the ability of the eyeball to rotate inward and outward, so that the visual axes of both eyes move continuously to train the three muscles that dominate vision, namely the ciliary muscles, extraocular muscles and iris muscles. Through coordinated training, the paralysis and stiffness of the above muscles can be relieved, making them strong and flexible, thereby improving the adjustment ability of the eye muscles, and ultimately achieving clear imaging of objects on the retina and restoring vision.
[0003] At present, when the vision function test equipment is used, the equipment is worn on the eyes so as to detect the eyeballs through infrared rays. However, when such vision function test equipment is worn, since it is necessary to maintain the stability of the vision function test equipment, it is usually necessary to fix the vision function test equipment directly on the eyes. This can easily cause fatigue and damage to the eyes when the vision function test equipment is bound for a long time. At the same time, the vision function test equipment is too closed around the eyes, making the pores around the eyes unable to breathe. Therefore, after a long period of training, it is easy to cause secondary damage to the skin around the eyes. Utility Model Content

A groove is provided on the outer surface of the outer baffle plate 2. A slider 54 is fixedly installed on the end of the visual function frame 1 close to the outer baffle plate 2. The slider 54 slides The visual function frame 1 is movably installed inside the groove. The outer surface of the visual function frame 1 is provided with a limit screw 55 for limiting the outer baffle 2. The limit screw (55) cooperates with the slider (54) to limit the outer baffle (2), so that the movement range of the outer baffle (2) is controlled to prevent the outer baffle (2) from moving too much, thereby causing pulling and damage to the components inside the visual function tester. The viscoelastic damper 51 is arranged between the visual function frame 1 and the outer baffle 2. The visual function frame 1 is fixedly installed with two first slide plates 52 on the inner wall close to the viscoelastic damper 51.

The viscoelastic damper (51) can be protected by the first slide plate (52) and the second slide plate (53), thereby preventing the viscoelastic damper (51) from being affected by external dust and water vapor and causing damage.
[0023] When in use, the visual function tester is worn by the first strap (31) and the second strap (4) so that the visual function tester can be stably mounted on the eyes of the person. At this time, the viscoelastic damper (51) provided inside the visual function tester can provide a buffering and pressurizing effect on the eyes of the wearer, so that the pressure generated by wearing can be kept balanced and stable, thereby improving the detection stability and preventing the straps from being too tight and causing damage to the eyes.
[0024] Embodiment 2:
[0025] On the basis of the first embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the outer surface of the visual function frame 1 is provided with an auxiliary mechanism 56, and the auxiliary mechanism 56 includes a heating plate 563 and a pad 561. The pad 561 is provided on the surface of the visual function frame 1 close to the eye, and the heating plate 563 is fixedly installed inside the pad 561. The surfaces of the heating plate 563 and the pad 561 are provided with a plurality of exhaust holes 562. The heating plate 563 cooperates with the air holes to micro-heat the area around the eye. This micro-heating can activate the blood circulation of the eyes of people who wear the visual function tester for a long time, so that The blood flows more smoothly, thereby improving the accuracy of vision examination. The interior of the pad 561 near the heating plate 563 is connected and installed with a connecting pipe 564. A cylinder 565 is fixedly installed on the top of the visual function frame 1. A piston 566 is arranged inside the cylinder 565. A first spring 568 is fixedly installed between the piston 566 and the cylinder 565. A circular hole is opened on the top of the cylinder 565. The bottom end of the cylinder 565 is connected and installed with the connecting pipe 564, and the end of the cylinder 565 away from the connecting pipe 564 is connected and installed with a heat conduction pipe 567.
[0026] During specific use, the visual function testing and training equipment of the utility model can perform micro-heating around the eyes through the heating plate 563 and the air holes when using the visual function tester. This micro-heating can activate the blood circulation in the eyes of people who wear the visual function tester for a long time, making the blood flow more smoothly, thereby improving the accuracy of vision examination. At the same time, when the heat flow emitted by the heating plate 563 increases, the piston 566 inside the cylinder 565 is pushed out through the effect of thermal expansion and contraction until the heat pipe 567 is connected to the inside of the cylinder 565. At this time, the excess heat flow generated outside the heating plate 563 can be discharged through the heat pipe 567, so that the heat flow around the pad 561 is kept in a balance, thereby further protecting the eyes.
