Description

Vision health instrument

This utility model relates to a kind of physical therapy appliance, specifically, is the improvement of a kind of training aids, is used for vision care.

Have the myopic eye preventing and treating instrument of numerous species type to sell in the market, their mechanism of curing the disease, apparatus structure are not quite similar, and be that have even widely different, and its therapeutic effect also has tangible difference.The inventor to the research and the clinical ophthalmology practice of theories of vision, thinks that the Yp-6 type myopic eye preventing and treating instrument of Shanghai Physiology Inst., Chinese Academy of Sciences's exploitation is more satisfactory according to for many years, and it is particularly suitable for the treatment of teenage pseudomyopia.This myopic eye preventing and treating instrument system utilizes optical imaging concept, makes patient's eye do clocklike to come and go the focal adjustment motion, scientifically tempers eye ciliary muscle and medial rectus, reaches the purpose of the regulatory function of improving them.Its optical system comprises lens barrel, achromat, sighting target and light source.During treatment, the patient's eye pupil is on the focal plane of lens, and sighting target is positioned at the opposite side of lens, and under the driving of machine one electric parts, oscillation cycle moved before and after sighting target was done along optical axis, motion amplitude is equivalent to sighting distance from infinity to 10 cm range, simultaneously, make light source follow the tracks of sighting target synchronously, guarantee that the sighting target illuminance is constant.Its weak point is that the spatial frequency of sighting target image is too abundant and immobilize, and is difficult to adapt with patient's vision, affects the treatment, and simultaneously, also limit treatment and health care scope can not be used for the treatment of amblyopia and presbyopia.

The purpose of this utility model provides the vision care instrument that a kind of sighting target image space frequency and patient's vision adapt, and is particularly suitable for the naturopathy of myopia, amblyopia and Presbyopia and is used for the asthenopic health care of normal eye.

Implementation basis of the present utility model is: 1. the visual space resolving power is corresponding with vision, the person of having good eyesight, and its spatial resolving power height, weak-vision person, its spatial resolution is low; 2. the employing optical imagery is implemented clocklike round focusing motion to eyes, tempers eye ciliary muscle and medial rectus, can remove visual fatigue, also can improve the spatial resolving power of patient's eye.Therefore, this utility model adopts existing YP-6 type myopia control instrument improved technical scheme in addition, change fixation target into convertible sighting target: to myopia and amblyopia eye, provide and the corresponding single spatial frequency sighting target series of vision, normal eye visual fatigue is adopted the multicolour pattern sighting target.Be that this utility model comprises: 1. the optical system of forming by lens barrel, achromat, sighting target and light source, the sighting target driver part that 2. constitutes by motor, rotating disk, connecting rod and planker, 3. sighting target transmission part and 4, with the suitable serial sighting target sheet of vision.

The utility model has the advantages that: 1. can provide rational spatial frequency sighting target to the patient, implement best visual stimulus, promptly so-called " suiting the remedy to the case " improves curative effect greatly; 2. enlarge the health care scope, can not only prevent and treat myopia effectively, also can treat amblyopia and improve presbyopia, and remarkable result is also arranged eliminating the eyestrain; 3. simple in structure, easy to implement.

This utility model is implemented by the following drawings.
