Description

Vision training apparatus

Technical field

This utility model relates to the medical rehabilitation Instrument technology field, relates in particular to the vision training apparatus of a kind of related preventive and visual rehabilitation health care.

Technical background

Myopia of student is to have a strong impact on the able-bodied social public health problem of teenager, and the prevention of myopia of student eye and rehabilitation are the key problems that whole world ophthalmology, eye optometry area research are explored always.

Show according to research: main cause with development takes place the myopia of student eye is excess eye-using closely.And be the demand of current social overall situation to vision with eye closely for a long time, myopiaization takes place for eyeball physiology, structure is that visual organ is to see the physiological adaptability that visual demand produced of nearly thing for a long time.Closely excessively cause the process of myopia with eye, reversible eyeball physiological change pro-, irreversible eyeball structure change after; In case variation has taken place in eyeball structure; Influence the eyeball physiological change again conversely, enter into the vicious cycle of reciprocal causation, cause myopia constantly to be deepened.Therefore, if can carry out visual training, expand the positive and negative range of accommodation of eyes to above problem; Improve susceptiveness and accuracy that eye is regulated, it is plain with two former reasons that eye causes axis oculi to solve low coverage, i.e. out of focus and form deprivation behind the retina; Transfer the physiological potential of eye, adapt to and closely use eye, resist eyeball structure and change; Be the axis oculi supernormal growth, the just effectively development of the generation of prevention and control myopia of student and the near-sighted degree of depth.

At present; The adjusting exercise equipment of related preventive and visual rehabilitation health care both at home and abroad; Its Optical devices partly are by the trainer and are held in the hand the turning operation that carries out optical surface; This kind device defect is a lot: the one, optical glass with by the angle mirror of trainer's eyes apart from can not remaining at correct distance, effective mirror degree of optical glass constantly changes, the training effect is bad; The 2nd, the angle out of plumb of eyes and minute surface can produce prism effect, brings out serious asthenopia; The 3rd, when switching the optical glass of the different number of degrees, often can not switch fast and put in place, influence the training effect.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned defective and a kind of simple in structure, easy to use, vision training apparatus that the training effect is good is provided.

For realizing this purpose; A kind of vision training apparatus that this utility model designed; Comprise airtight cabinet, the medial surface of first end face of said cabinet is provided with panel, and the medial surface of second end face parallel with first end face is provided with visual acuity chart; The medial surface of said panel is provided with handsetting gear and two eyeglass gears that are meshed with it respectively; The location jump ring is installed on the said handsetting gear, on the said eyeglass gear a plurality of optical glasss is installed, be respectively equipped with the hagioscope of perspective optical glass on first end face of said cabinet and the lateral surface of panel.

In technique scheme, the handsetting gear medial surface is provided with and locatees the arcuate groove that jump ring matches.

In technique scheme, said two eyeglass gears are provided with the vision scale, have an X-rayed the graduated display window of vision respectively on first end face of said cabinet and the lateral surface of panel.

In technique scheme, on the said cabinet bottom surface adjustable for height base is installed.

In technique scheme, said visual acuity chart is a LED lamp box visual acuity chart.

Adopt the following advantage that the utlity model has of technique scheme:

This utility model is installed the optical glass group respectively and is switched panel and visual acuity chart on two parallel surfaces of cabinet, can guarantee in training process, optical glass with by the angle mirror of trainer's eyes apart from remaining at correct distance, effectively improved the training effect; Hagioscope and optical glass are separately positioned on the same panel, the line of effectively controlling eyes and lens optical center with paralleled by trainer's sight line, effectively avoid producing prism effect; Through handsetting gear, cooperate the optical glass of the different number of degrees of jump ring realization switching on the handsetting gear, promptly accurately quick again, easy and simple to handle convenient again, further effectively improved the training effect.In addition, this utility model adopts airtight cabinet, can make by two eyes training of trainer not disturb each other, and make trainer's attention not be subject to the foreign object influence, is convenient to focus one's attention on, thereby has improved the training effect.

Carry out the physics training of myopia ciliary muscle through this utility model, exercise can effectively be improved the sensitivity of a ciliary muscle by trainer's inner and external flesh of eyes contractility, and strengthens the ability that eyes itself are resisted myopia.
