Description

Improve the vision care instrument of structure

This utility model relates to a kind of architecture advances of vision care device, specifically, be the architecture advances of the control of a kind of color, bright dark change frequency and sighting target kinestate, make the naturopathy of myopia, amblyopia and Presbyopia and more obvious to the asthenopic health-care effect of normal eye to the sighting target bias light.

Vision care is almost closely related with everyone, each family, therefore, to the naturopathy of myopia, amblyopia and Presbyopia and commercially available for some time various in style to this class eye care instrument of asthenopic health care of normal eye, unexpectedly it is very fierce to strive, but the market economy rule is merciless, the survival of the fittest, and nowadays this series products has obviously lacked, the patent No. is that 89215236.2 " vision care instrument " is one of competitive product, and is still quite popular with users.The disclosed technical scheme of this patented technology is to adopt optical imagery, eyes are implemented clocklike round focusing motion, temper eye ciliary muscle and medial rectus, and the spatial frequency sighting target cross-eyed that selection and vision adapt stimulates, and promptly this patented technology comprises the optics that become according to the light path associative structure by light source, sighting target sheet, clear aberration lens and lens barrel, mounted by sighting target and put the transmission of rotation that serial sighting target sheet and drive mechanism constitute.The sighting target driver part that the sighting target transmission part of the sighting target sheet in this optics, this sighting target transmission part of driving that is made of guide rail, planker, connecting rod, rotating disk, motor make sighting target move forward and backward along the optical axis of optics, and casing is installed.The advantage of this patented technology is to improve patient's eye ciliary muscle and medial rectus, can " suit the remedy to the case " again, the patient is implemented the sighting target that spatial frequency and vision adapt to be stimulated, enlarged 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 to eliminating the eyestrain, this obviously is a kind of technological progress, yet in clinical practice for many years, also find its part that still haves much room for improvement, its shortcoming is: fail to provide best sighting target bias light color, to reach optimum curative effect 1.; 2. fail to provide sighting target cross-eyed optimal stimulus frequency; 3. do not control the function of sighting target kinestate, these all limit the further raising of its health-care effect to a certain extent.

The purpose of this utility model is the shortcoming that overcomes above-mentioned existing vision care instrument, and a kind of improvement structure of vision care instrument is provided.

Technical solution of the present utility model is: with Chinese utility model patent CN 89215236.2 " vision care instrument " is foundation, set up sighting target kinestate control unit, sighting target yellow background light member, the dark change frequency control unit of sighting target background light, be that this utility model comprises optics, the sighting target frame of putting serial sighting target is arranged and change the sighting target transmission part that the sighting target sheet in the optics is provided, drive the sighting target transmission part and make the sighting target driver part of sighting target sheet by motor along the axis movement of optics, and installation casing, be characterized in: the light source in this optics is installed in one to be had in the single face printing opacity casket of yellow filter, and have one to dodge this light source of driver drives frequently, and the illumination of control sighting target and the functional switch of kinestate and the regulating frequency potentiometer of this sudden strain of a muscle frequency driver be set in the appropriate location of casing.

The utility model has the advantages that: 1. " the repertoire of vision care instrument, also being particularly suitable for ametropic amblyopia and mistaken diagnosis is the bathomorphic treatment of amblyopia eye except that having CN 892155236.2 utility model patents; 2. use yellow point of scintillation, make photoreceptor cell obtain fever, help the functional oppressive recovery of photoreceptor cell; 3. high-intensity background passage of scintillation light increases incident ophthalmic light quantum, improves the useless functional rehabilitation with the property macular area of form deprivation amblyopia; 4. adopt fine definition achromatism compelx coating lens, optics imaging scope and definition are increased greatly, help the cross-eyed stimulation of sighting target sheet; 5. the serial spatial frequency sighting target sheet warp of existing patent and cooperating of flasher have improved the time response and the spatial character of sighting target image.
