The method of utilizing this utility model to check is as follows:

Inspection can be carried out in bright chamber or darkroom.Answer bore hole and eyes fixing upward eyeball to check respectively, the examinee puts on mycyscope (wear red left eye for right eye as usual and wear green) and watches the traffic lights on the check surface.Can analyze examinee's binocular single vision function according to the finding figure.Understand for the ease of the eyes tradesman, now take the method for learning to read with the aid of pictures, when watching putting on mycyscope, the figure of seeing is explained.For convenience of description, above lamp, following lamp, left lamp and right lamp are represented four LED lamp groups respectively respectively, and wherein going up lamp is red light, and following lamp is white lamp, and left lamp and right lamp are two green lights of level.

1, when finding be that last lamp, left lamp and right lamp are original color, and down lamp be white or yellow, perhaps playing lamp is that half of red one side of something is green, illustrates that then the tester has the binocular single vision one-level to look simultaneously and secondary fusion visual function, but does not have the branch of dominant eye and nondominant eye.

2, when finding be that last lamp, left lamp and right lamp are original color, and down lamp be red, because following white is regarded redness as, so be dominant eye according to the dominant physiological characteristics right eye of the color of leading eye.

3, when finding be that last lamp, left lamp and right lamp are original color, and down lamp be green, because following white is regarded green as, so be dominant eye according to the dominant physiological characteristics left eye of the color of leading eye.

4, the somebody will play lamp to regard a little while red as, and will be green a little while, illustrate that two eyes retinas are waging a struggle, and be a kind of performance of not having obvious dominant eye.

In four kinds of situations of above 1-4, binocular single vision firsts and seconds function is described, but not talkatively look state admittedly all are normal, because stravismus patient's unusual angle equals him when feeling the angle of strabismus, namely the corresponding patient of so-called harmonicity abnormal retinal also may see as above situation.

5, when finding be the original color of last lamp, following lamp redness, left and right sides lamp can't be seen, illustrates that the left eye of wearing green len is suppressed.

6, lamp green under finding is, left and right sides lamp is original color, can't see and go up lamp, illustrates that the right eye of wearing red eyeglass is suppressed.

7, the someone be 5 and 6 two kind of situation alternately occur, illustrate that eyes are in alternately inhibition.

Under these three kinds of situations of 5-7, illustrate that all the tester does not have eyes haplopia function.

8, when finding be the original color of lamp on the right side, following lamp redness, and lamp green under the left side, left and right sides lamp is original color, all the other can't be seen, are referred to as the direct diplopia, if this situation betides the esotropia patient, are illustrated as normal retina correspondence; As betide exotropia patient, be illustrated as the abnormal retinal correspondence.

9, when finding be lamp green under the right side, left and right sides lamp is original color, and the original color of lamp on the left side, following lamp redness, all the other can't be seen, are referred to as crossed diplopia, if this situation betides the esotropia patient, are illustrated as the abnormal retinal correspondence; As betide exotropia patient, be illustrated as normal retina correspondence.

Under two kinds of situations of 8-9, illustrate that the tester has the i.e. while visual function of binocular single vision one-level, does not namely merge visual function and there is secondary.

This utility model provides the treatment principle as follows:

1, determines dominant eye: according to the dominant physiological characteristics of the color of dominant eye, when eyes are opened simultaneously, when seeing down lamp, often be shown as the color of dominant eye.Wear red as right eye routinely, left eye is worn embolium, if down lamp to take on a red color be that right eye is dominant eye, it is that left eye is dominant eye that following lamp is green.If down or lamp is white in color or yellowly can half of red one side of something is green illustrates that namely the tester does not have the branch of dominant eye and nondominant eye.In addition, when dominant eye and nondominant eye difference were little, the eye of wearing green len was subject to suppress, and regarded red easily as, when therefore determining dominant eye, will exchange determine that at last dominant eye is comparatively accurate several times about mycyscope.

2, check the binocular single vision function: the binocular single vision function is divided into three grades, and namely one-level is looked simultaneously, and secondary merges looks three grades of stereopsis.This utility model can be looked into one-level and look simultaneously to merge with secondary and look.Open simultaneously when seeing when wearing the mycyscope eyes, as seeing a kind of color, then expression has the visual function of glasses to be suppressed, and does not namely have the while visual function.If can see red simultaneously and green namely represents to have the while visual function.As seeing four lamps simultaneously, following lamp is only regarded a color as, i.e. expression has fusion visual function (being that the white lamp that eyes are also seen eyes respectively when seeing white lamp simultaneously is fused into).Though can see the green two kinds of colors of show simultaneously, what see is five lamps, though namely eyes can be looked simultaneously, can not be fused into the white lamp that following eyes are seen respectively one, i.e. the amixis visual function.

3, the objective indicator when joining the mirror prescription is opened in anisometropia.Irregularly actually when mirror is joined in anisometropia allowed muchly, do not had reliable objective indicator all the time.Reliable objective indicator when utilizing this utility model to detect to be anisometropia to join mirror no matter namely anisometropic size all must have the fusion visual function, as long as the fusion visual function is arranged, just needn't be haggled over anisometropic size.

Utilize instrument for training of the present utility model, can adjust the distance between tester and the lamp group easily, can adjust the light source area simultaneously.Test is carried out with reference to table 1-3.
