The near point using method step of visual performance optimization rehabilitation training equipment of the present invention is:
A keeps the brightness and the visibility of sighting target, and every numerical value makes zero and adjusts equipment level position, seat height, nearly eye distance, singly inserts interpupillary distance, corrects the number of degrees according to optometry, closes the set pincers of special-purpose optometry dish;
The b sighting target adopts " intersection lines sighting target ", should be near more good more, and user is watched sighting target all the time attentively;
The c minus lens that progressively progressively increases is until feeling that sighting target is smudgy for the first time, the record reading;
D moves forward and backward sighting target, makes user see clearly increasing minus lens behind the sighting target more gradually fuzzy to sighting target, moves forward and backward sighting target again, additional degree of record and the time of seeing sighting target clearly, adjusts repeatedly, until seeing sighting target again clearly, the record reading.
The far point using method step of visual performance optimization rehabilitation training equipment of the present invention is:
A keeps the brightness and the visibility of sighting target, and every numerical value makes zero and adjusts equipment level position, seat height, nearly eye distance, closes the set pincers;
B adjusts the window of special-purpose optometry dish apart from the interpupillary distance that meets eyes, selects to meet E table 0.4 sighting target of 60 cm distance, and sighting target is placed 60 centimetres of positions, and the scioptics compensation temporarily is adjusted to the eyes of user respectively-the 2.00D diopter;
The c user is recognized sighting target from top to bottom line by line, one by one, if user can be recognized whole sighting targets smoothly, then can adjust convex lens load, and eyes increase+0.50D synchronously, requires user to recognize sighting target from top to bottom line by line, one by one subsequently again; If user can not be recognized 0.4 sighting target, that just begins to recognize downwards line by line from the delegation of the clear identification of energy;
When d occurs recognizing that when user wrong or recognition is had any problem, allow user conscientiously make great efforts, watch repeatedly, perhaps please sighting target is adjusted into " reticule " sighting target of standard, the operator allows sighting target move several times apace by manual mode;
Convex lens load constantly repeats said process, till can not increase again.
The meticulous using method step of visual performance optimization rehabilitation training equipment of the present invention is:
A keeps the brightness and the visibility of sighting target, and every numerical value makes zero and adjusts equipment level position, seat height, nearly eye distance, closes the set pincers;
B hides eyes, and another is corrected-2.00D myopia, and sighting target is placed on it corrects the far point place; Select astigmatism dish mark as the training sighting target;
C such as user find that the sighting target lines are unintelligible, then make great efforts to see, up to can see clear till, the manipulate person who sees manually moving target stimulates the conditioned reaction of user;
After the d user confirms that astigmatism dish target lines are all clear, increase post mirror load, since 180 positions, repeat the process of above-mentioned c, after user reaffirmed that astigmatism dish target lines are all clear, the axle position of rotational load post mirror changed 30 degree at every turn, up to finishing a circle, continue to repeat above-mentioned c process.
E can also increase post mirror load subsequently, carries out the use of a new round.
The ocular movement using method step of visual performance optimization rehabilitation training equipment of the present invention is:
A keeps the brightness and the visibility of sighting target, and every numerical value makes zero and adjusts equipment level position, seat height, nearly eye distance, singly inserts interpupillary distance, corrects the number of degrees according to optometry, closes the set pincers;
B user bore hole or load certain number of degrees, user is dig-inned sighting target, the speed of setting the sighting target motion and changing;
C progressively increases the motion and the pace of change of sighting target.
The light and shade of visual performance optimization rehabilitation training equipment of the present invention stimulates using method to be: sighting target is bright, alternately dark, and bright, the dark frequency of the sighting target that progressively changes.
Special-purpose optometry dish is to have added a cover mirror (concavees lens of 20D or+convex lens of 20D) on commercially available general optometry dish basis among the present invention.Comprise parts such as all the positive and negative spherical lenss among the general optometry dish, negative cylindrical lens, prism, set pincers in the special-purpose optometry dish.Screen can be along the screen guide rail movement among the present invention, and the optometry dish guide pillar limit parallel with table top can slide up and down along another limit, drives special-purpose optometry dish and moves up and down.
The sighting target height sees in 60 centimeters that below 1 millimeter the sighting target of visual acuity chart (being general E word visual acuity chart) 0.4 size can be considered 1.0 sighting targets among the present invention.
When visual performance optimization rehabilitation training equipment of the present invention used, user was sitting in by the falsework, and eyes are over against the window of special-purpose optometry dish, see through window naked look or load observe various sighting targets.The sighting target controller can be controlled and show various sighting targets on the screen, and can control its motion mode and speed.
Visual performance optimization rehabilitation training equipment of the present invention is according to myopia, hypermetropia, astigmatism, stravismus, formation theory such as amblyopia and presbyopia, feature at its origin cause of formation, the brand-new training theory of regulating of utilization, can effectively adjust the visual state of eyes, realization is at comprising that brain image forms, the visual central nervous system control system, be optimized for core with regulatory function, comprise adjusting, the inside and outside muscular strength and the ocular movement of set eyeball, strengthen eyes self regulation function comprehensive visual performance outward bounds such as (as: amplitude of accommodation and reaction speed etc.), thereby reach the lifting vision, improve the eye refractive status, make the visual performance of eyes be strengthened comprehensively and optimize, also be fundamentally to improve into the problem that image focus and axiallength are not complementary, the recognition capability of effective stimulus retina and visual centre makes myopia, amblyopia, astigmatism, the vision fast lifting and the lasting stability of presbyopia.
The present invention has following beneficial effect:
1 regulates training and optimizes: comprise the optimization and the expansion of the amplitude of accommodation, conditioned reaction, limit adjusting, meticulous adjusting and negative regulation ability.
2 ocular movements training with optimize: the eyeball that to comprise with inside and outside up and down rectus be core is synchronized with the movement and above inferior obliquus is the relative conjugate movement of eyeball of core, and the lifting of these motions or motor capacity is to the influence of ocellar structure, eyeball form;
The training and the optimization of 3 brain visions, mental image: the influence under static or dynamic visual testing sign (and image) system guides to retina, visual cell, optic nerve, big mesencephalic centre, visual area cortex;
4 amblyopias are trained the adjustment of optimization, focus point position, the improvement of retina image-forming quality and the value that the limit is regulated outward bound with the regulatory function in adult's amblyopia training;
The prevention and control of 5 juvenile myopia and treatment: the raising of the close eye ability of improving based on visual performance is in the improvement of the visual capacity under the myopia out-of-focus appearance to the influence of occurrence and devlopment of myopia.
6 are different from treatment meanss such as traditional operation, medicine, acupuncture, are the physics training methodes, safe and reliable, have no side effect.
7 can formulate personalized training program according to the concrete condition of everyone eyes, and with strong points, effect is remarkable.
