Abstract

The utility model relates to a dominant eye tester. A front observation port is arranged at the middle part of the front side of the outer body of a test, a laser lamp emitting hole is respectively arranged at the upper middle part of the front side, and the lower middle part of the back side of the of the outer body of the test; a battery switch is connected at the right side of the tester, an upper laser lamp is connected to the upper middle part of an inner surface of the upper side, a lower laser lamp is connected to the lower middle part of an inner surface of the lower side, and two batteries are connected to an inner surface of the right lower side; and the dominant eye tester is successfully assembled by connecting the two batteries, the battery switch, the upper laser lamp and the lower laser lamp. When the tester is used, a testee can choose an object or character 2.5m to 5m away as the target, and lift the tester by hand horizontally with eyes passing the front observation port and a rear observation port to observe the target, a light spot emitted by the upper laser lamp can fall on a brow above the dominant eye of the testee, and the eye below the brow is the dominant eye. The dominant eye tester has the benefits of quickness, accuracy and direct viewing, different groups of people can easily understand and accept, and errors caused by human factor are eliminated.

Description

Dominant eye tester

Technical field

This utility model relates to eyes and looks the optical tester field, is specifically related to dominant eye tester.

Background technology

People are when looking thing, and the eyes role is often inequality, and wherein a glance is often preponderated to a certain extent, the main burden person who becomes the location, causes fusion, and this eye is called the master and looks eye, also is leading eye.The main eye of looking is one of human more common laterality functional character.The main eye of looking can become, and the so-called main eye of looking is that brain mainly relies on this eye object, just as our hands, wants to take cup, and we get used to the main wherein hands of using.

This notion is proposed by Porta as far back as nineteen fifty-three, and according to its classification, some of them artificially left side master are looked eye, are designated as levorotation (L type), and other artificial right masters look eye, are designated as right type (R type).The research of looking eye mainly concentrated on oblique amblyopia and the mirror aspect is joined in optometry to leading in the past, relevant main inspection method of looking eye is reported less, and determine that the main eye of looking joins mirror to design, other selection of eye of operation eye and the optometry of the selection of strabotomy muscle, amount for surgical size and all have than the important clinical meaning, therefore select one simple, method and instrument that the inspection master of easy to understand and accuracy of judgement looks eye seem particularly important.Main traditional assay method of looking eye has following several:

The finger method: selecting a 5m vertical line at a distance is target, and this vertical line of binocular fixation stretches out right hand forefinger, makes finger block vertical line, at this moment closes eyes arbitrarily, and this eye was not the main eye of looking when finger departed from vertical line when certain eyes are opened;

4 instrument methods of Worth: the testee sits up straight before the comprehensive optometry instrument, the testee should fully be corrected on the comprehensive optometry instrument if any ametropia, 4 sighting targets of Worth are incident upon on the projector, the patient sees 4 sighting targets of Worth by the comprehensive optometry instrument, the white sighting target in below shows that as showing that red partially explanation right eye is the main eye of looking green partially explanation left eye is the main eye of looking.

Card hole method: the testee sits up straight and looks squarely, select 5m distant place one object as target, require testee's eyes to watch this object simultaneously attentively, both hands are flat then lifts test chart (a middle card that has diameter 3cm circle hole of 20cm * 13cm) and requires the testee from the hole sight line to be concentrated on the target, advise the patient's head and the sheet hands that holds to move, it is simple eye to hide the patient more respectively, can see that still the eye of target is the main eye of looking.

The finger method is more simple, does not need to check utensil, but finds sometimes, and relatively other two kinds of methods are difficult is understood by the patient for its, and the part patient usually regards a finger as two fingers and causes inspection to carry out;

4 instrument methods of Worth are understood because of being convenient to the child, thus comparatively suitable in child's eye muscle is checked, but this method needs specific inspection apparatus, lights a lamp as comprehensive optometry instrument or Worth four.It is to check a kind of method of feeling to melt picture that Worth four lights a lamp, checking the main subjective judgment of the result of its inspection at the moment of looking from the patient with it, the influence that it not only is subjected to the patient to feel, understand and judge, also be subjected to the interference of color, while inhibitory reaction, double image react, melt the picture reaction and also the result produced considerable influence, there is the part patient below seeing 4 sighting targets of Worth, can't provide the judgement of accurate unanimity in the white sighting target, they often complain that white sighting target reddens for a moment, turns green for a moment, sometimes a white sighting target are regarded as red green two.

Card hole method is simple and easy to do, and inspection method is also more easily understood by the patient, but also has following shortcoming: an observation port size, easily cause mistake from observing the far and near difference of eye; The 2nd, the examinee covered when simple eye unconscious the moving of head easily cause mistake; The 3rd, the patient expresses unclear or be beyond expression (as: child, dialect, deaf and dumb etc.) causes mistake; The 4th, optometrist should be observed tester's gesture actions, and to indicate distant object also will hide the tester again simple eye, and the abecedarian is often in a rush easily to make mistakes.

The above the main existing drawback of traditional assay method and defective of looking eye never has the solution of good technical scheme.

Summary of the invention

The purpose of this utility model provides and a kind ofly is convenient for people to which eyes are main dominant eye testers of looking eye in measuring eyes, uses this dominant eye tester, and not only fast, accurately but also directly perceived, all kinds of crowds are readily appreciated that, accept.

For achieving the above object, dominant eye tester of the present utility model is realized in the following manner: combined by tester ectosome, last radium-shine lamp, following radium-shine lamp, binodal battery, cell switch and lead, preceding peephole is established at middle part, tester ectosome front, the middle and upper part is established radium-shine lamp and is penetrated the hole, and middle and lower part, the back side is set radium-shine lamp and penetrated the hole; The right side connects cell switch, and upside inner face middle and upper part connects goes up radium-shine lamp, and downside inner face middle and lower part connects radium-shine lamp down, and the lower right side inner face connects the binodal battery; Connect binodal battery, cell switch, last radium-shine lamp, following radium-shine lamp with lead, whole dominant eye tester is just assembled success.During use, the target of looking at gaging hole and 2.5 meters～5 meters connects being aligned after testee's two the pasts peephole, the warp, open cell switch, when the hot spot that radium-shine lamp penetrates under the testee sees from peephole just in time was radiated at and looks on the target, the hot spot of going up radium-shine lamp ejaculation will be radiated at testee's brows place, if impinge upon right eye brows place, testee's right eye is the main eye of looking, if be radiated at left eye brows place, testee's left eye is the main eye of looking, and measuring once only needed for 15 seconds.

Adopt this utility model structure, its beneficial effect is: quick, accurate and directly perceived, different crowd is understood easily, is accepted, and has got rid of the human error factor.

Below in conjunction with the drawings and specific embodiments this utility model is described in further detail.
