Description
Technical Field
The invention relates to the technical field of eye exercise physiotherapy devices.
Background
Common visual function problems include myopia, hyperopia, astigmatism, strabismus, amblyopia, presbyopia and the like, and methods for wearing glasses or performing surgical treatment are generally adopted to solve the problems, but as is well known, the glasses can only correct the habit of eyes to see things, but can not cure the diseases, and the current method capable of truly curing the myopia of eyes is surgery, but the surgery has a certain risk, especially for the current juvenile population, and the eyes are still in a developmental stage.
To overcome these problems, a series of therapeutic means and devices such as the mist method have been developed. Chinese patent CN101773443a discloses a device for visual function optimization rehabilitation training. The invention comprises a supporting frame, a working frame, a special optometry disk, a vision screen guide rail, a vision mark controller and a guide rail column; the support frame includes square mesa, and the mesa below is provided with the stabilizer blade, sets up optometry dish guide pillar and guide rail support on the mesa, and optometry dish guide pillar and the parallel limit of mesa and another limit swing joint, and the work frame sets up on the mesa be close to the position of optometry dish guide pillar, special optometry dish is connected optometry dish guide pillar and the parallel below of mesa limit, and be close to the work frame. One end of the vision screen guide rail is fixedly connected with the guide rail bracket, and the other end of the vision screen guide rail is fixedly connected with the top of the guide rail column. The guide rail column is supported on the table top or the ground, and a disc-shaped sleeve lens is arranged at the position of the sight hole of the universal optometry disk serving as the special optometry disk; the visual screen is arranged below the visual screen guide rail and can move along the visual screen guide rail, and a visual target is displayed on the visual screen. The eyeball movement using method of the vision function optimization rehabilitation training device comprises the following steps: a, keeping brightness and visibility of a visual target, zeroing various numerical values, adjusting the horizontal position of the equipment, the height of a seat and the near-eye distance, putting the pupil distance and the correction degree according to an optometry bill, and closing the collecting clamp; b, the naked eyes of a user or a certain degree of loading is carried out, the user stares at the sighting target, and the movement and the change speed of the sighting target are set; c gradually increasing the movement and rate of change of the optotype. The visual target moves to regulate and integrate the internal and external muscle strength and eyeball movement of the eyeball, strengthen the self-regulating function (such as regulating amplitude, regulating response speed and the like) of the eye and the like, thereby improving the vision, improving the refractive state of the eye and comprehensively strengthening and optimizing the visual function of the eye.
Some people exist, and the eyes of the people have certain defects in terms of perceived color, so that the situation not only can influence visual chromatic aberration, but also can influence vision. The principle is that different colors of light have different wavelengths, so that the color light with the same distance can generate a visual distance difference when the color light is absorbed into human eyes. For example, for myopes, two optotypes at the same distance, one of which is red and the other of which is green, the patient will often see one piece more clearly than the other when viewing, i.e. each person will have a color of his own preference due to the different eye configurations.
The existing eye optometry equipment or treatment equipment is used for detecting the near-sighted degree, far-sighted degree and astigmatic degree of eyes of patients and then correcting and treating, and no device is used for detecting the preferential colors of the near-sighted patients and the far-sighted patients, the eyesight of the patients can be enhanced by utilizing the preferential colors of the patients, and the preferential colors are added into the lenses of the eyes of the patients, so that the degrees of the correcting glasses can be reduced, and the pressure of the eyes is lightened.
