Abstract

The utility model discloses a presbyopia therapeutic apparatus, which comprises a case on the side wall of which an observation window is arranged. Two optical lenses are arranged horizontally at intervals at the observation window in the case; and an LED display screen controlled by a control circuit is fixed on the inside wall of the case which is opposite to the observation window. The presbyopia therapeutic apparatus has the advantages of improving blood supply of the ciliary muscle and promoting the crystalline lens to change the focus continually so as to improve the plasticity and adjustment ability; the alternative motion of the four rectus which are in, out of, above and below the eyes constantly produces the actions of drawing and pressure on eyeball and speeds up the rise of the intra-ocular pressure so as to lead the antero posterior axis of the eyeball to be lengthened, thus improving the presbyopia degree, deferring the occurrence and development of presbyopia. The presbyopia therapeutic apparatus has no mechanical drive in the working process, thus leading to small volume and convenience for carrying about.

Description

The presbyopia therapeutic instrument

Technical field

This utility model relates to therapeutic instrument, especially relates to the presbyopia therapeutic instrument.

Background technology

Along with the growth at people's age, ciliary is myofunctional to go down that presbyopia to occur be inevitable.The resourcefulness that solves at present presbyopia is taked to wear glasses and is carried out vision correction, but the presbyopia glasses do not have the recovery visual function, after being with the presbyopia glasses, therefore the adjusting of the activity of ciliary muscle and crystal capsule remains static, and will cause that vision further weakens and has to deepen the optics number of degrees of glasses.How delaying generation, the development of Presbyopia, is the problem that people study always.

The utility model content

This utility model purpose is to provide a kind of improves the presbyopia degree, delay the presbyopia therapeutic instrument that presbyopia takes place, develops.

By the training of eye muscle being played the presbyopia therapeutic instrument of prevention visual deterioration, recovery vision.

For achieving the above object, this utility model can be taked following technical proposals:

Presbyopia therapeutic instrument described in the utility model, it comprises that sidewall offers the housing of observation window; In described housing, be positioned at horizontal interval, observation window position and be provided with two groups of optical lenses; On inner walls, be fixed with LED display by control circuit control with respect to observation window.

Described control circuit by oscillating circuit, counting circuit, timing circuit, cursor move control circuit, led drive circuit constitutes; Described output end of oscillating circuit is electrically connected with the input of counting circuit, timing circuit respectively; The outfan of counting circuit, timing circuit is electrically connected with mobile control circuit input respectively; Cursor moves the control circuit outfan and is electrically connected with the led drive circuit outfan.

This utility model advantage just is to take the horizontal interval to be arranged on the optical lens of two groups of adjustable focal length that are positioned at the observation window position in the described housing and is fixed on respect to the LED display by control circuit control on the inner walls of observation window.Like this, the fixing two cursor steady shifts of watching attentively on the LED display of people's head during use make inside and outside four the rectus alternating movements up and down of eyes increase the blood flow of muscular arteries, thereby improve the blood supply of ciliary muscle; Impel crystalline lens constantly to change focal length and improve its plasticity and regulating power; Inside and outside four the rectus alternating movements up and down of eyes constantly produce tractive and contention effect to eyeball, and the rising of quickening intraocular pressure makes it eyeball antero posterior axis lengthening, thereby improve the presbyopia degree, delay that presbyopia takes place, the development purpose.This utility model does not have mechanical transmission in the course of the work, makes volume little, is convenient to carry.
