Abstract

The utility model discloses a prism flipping bat, belonging to the technical field of optical detection. The prism flipping bat comprises a prism bat, wherein four lenses are symmetrically arranged on the prism bat, are triple prisms and are divided into two rows by taking a central axis of the prism bat as a symmetry line; the total prism degrees of the two rows of lenses are different; and the base directions of the two rows of lenses are opposite, namely the base directions of two lenses in one row are inward, and the base directions of two lenses in the other row are outward. The prism flipping bat has the advantages of: quickly and accurately detecting collection sensitivity of binocular vision; further inspecting clinical problems difficult to diagnose; providing more reliable basis for clinical diagnosis for the binocular vision; training patients with problems in collecting and diffusing functions according to symptoms; and having a simple structure and convenience for popularization.

Description

The prism upset is clapped

Technical field

This utility model relates to a kind of the be used for inspection of stereopsis vision set sensitivity and the upset bat of training, belongs to optometry detection technique field.

Background technology

At present, it is that the lens upset is clapped that known upset is clapped, and it is clapped with the upset mirror by positive minus lens and forms.Have general the branch: ± 0.50, ± 1.00, ± 1.50, ± 2.00, and ± 2.50 five kinds of specifications are mainly used in detection and the training of regulating sensitivity in the binocular vision function.The upset of examinee use ± 2.00D is clapped, and 20/30E word test-card in 40 centimeters, sees that the telescope direct degree is turned to that negative mirror degree is clear to be one-period after clear.Write down in 1 minute from the telescope direct degree to negative mirror degree change frequency clearly.Normal value is simple eye 11 cycles/minute, 8 cycles/minute of eyes.Yet in the binocular vision function, adjusting and set are inseparable, complementary.The upset of existing lens is only clapped and can checked and train to regulatory function, can not be used to gather the inspection and the training of sensitivity, has ignored set, the importance of training for binocular vision function scatters.

Summary of the invention

In order to overcome the weak point of above-mentioned prior art, this utility model provides a kind of prism upset to clap, and can detect and trains the set of stereopsis vision, the function of scattering.

This utility model is realized through following technical scheme: a kind of prism upset is clapped, and it comprises the mirror bat, and mirror is clapped and gone up symmetric four eyeglasses that are equipped with; Described four eyeglasses are prism; The axis that four eyeglasses are clapped with described mirror is that line of symmetry is divided into two rows, and total prism degree of two row's eyeglasses is different, and the end of two row's eyeglasses is on the contrary; Promptly one row two eyeglasses at the bottom of to inwardly, at the bottom of two eyeglasses of another row to outwardly.

Described four eyeglasses are while approaching thick circle or similar round eyeglass.

The beneficial effect of this utility model is: can remedy existing lens upset and clap the deficiency that only can detect the adjusting sensitivity of stereopsis vision; This utility model can detect the set sensitivity of stereopsis vision fast and accurately; And some problems that are difficult to clinically to make a definite diagnosis are done further inspection, for clinical stereopsis vision diagnosis provides foundation more reliably; Also can pair set, the in-problem patient of the function of the scattering training of suiting the medicine to the illness; Simple in structure, be convenient to implement to promote.

Description of drawings

According to accompanying drawing and embodiment this utility model is further specified below.

Fig. 1 is this utility model structural representation;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is the B-B cutaway view of Fig. 1.

Among the figure, 1, the eyeglass I, 2, the eyeglass II, 3, the eyeglass III, 4, the eyeglass IV, 5, mirror claps.

The specific embodiment

Clap like Fig. 1, Fig. 2, a kind of prism upset shown in Figure 3, it comprises that mirror claps 5, and mirror is clapped and symmetric on 5 four eyeglasses is housed; It is characterized in that: described four eyeglasses are prism, and it is that line of symmetry is divided into two rows that four eyeglasses are clapped 5 axis with described mirror, among the figure; Eyeglass I 1 is a row with eyeglass II 2, and eyeglass III 3 is a row with eyeglass IV 4, and the prism degree of two row's eyeglasses is different; And the end of two row's eyeglasses is on the contrary, promptly at the bottom of two eyeglasses of a row to inwardly, at the bottom of two eyeglasses of another row to outwardly.Described four eyeglasses are while approaching thick circle or similar round eyeglass, at this moment, the end to be meant webbing towards.

For the understanding of " inside and outside ", in be meant the inside region between two eyeglasses with row, be meant exterior lateral area outward with row two eyeglass two ends.Shown in accompanying drawing, with the I place be in, outside the O place is in contrast to this.Can not be interpreted as " in will being near the position that mirror is clapped 5 axis, the position that will clap 5 axis away from mirror be for outer ".As shown in Figure 2, eyeglass I 1 is that the end is to inwardly with eyeglass II 2; As shown in Figure 3, eyeglass III 3 is that the end is to outwardly with eyeglass IV 4.

The optional 4 kinds of specifications of prism (representing prism degree with Δ) are respectively: 3 Δs (BI) and 12 Δs (BO)---promptly a row is that 3 prism degrees (BI: the end is to inwardly), another row are 12 prism degrees (BO: the end is to outwardly); 6 Δs (BI) and 12 Δs (BO) 4 Δs (BI) and 16 Δs (BO) 8 Δs (BI) and 8 Δs (BO).

With 3 Δs (BI) and 12 Δs (BO) is example: eyeglass I 1 respectively is 1.5 Δs (BI) with eyeglass II 2, and addition gets 3 Δs (BI), and eyeglass III 3 respectively is 6 Δs (BO) with eyeglass IV 4, and addition gets 12 Δs (BO).During operation, the examinee is under the prerequisite of correction of refractive errors, and hand-held 0.7 file examination of near vision table is in 40cm place at the moment.The hand-held prism upset of examiner is clapped to examinee's eyes, with 12 Δs (BO) alignment examinee eyes, i.e. eyeglass III 3 and eyeglass IV 4; The examinee's right and left eyes that aligns respectively, the examinee checks sighting target on the vision test card through prism, sighting target is informed the examiner by fuzzy the change after clear; Examiner's mirror that overturns is clapped, with 3 Δs (BI) alignment examinee eyes, i.e. eyeglass I 1 and eyeglass II 2; The examinee's right and left eyes that aligns respectively, to clear this of examinee main suit be one-period.Carry out the upset inspection of following one-period afterwards again.Check the periodicity that per minute carries out, judge examinee's stereopsis vision set sensitivity thus.Normal reference value is 13 cycles/minute.Also method lets patient's training of suiting the medicine to the illness according to this.
