On 1 back side of mainboard, the lower section of dominant eye peep hole 2 is provided with control flume 8, and control flume 8 is rectangle, control It is provided with top setting in slot 8 there are two concatenated button cell 11, is provided with wiring board in control flume 8, it is embedding on the wiring board Equipped with LED lamp bead 10, button switch 9, wiring board is electrically connected by conducting wire with the positive and negative anodes of button cell 11；The LED lamp bead 10 faces shine circular hole, and the light of LED lamp bead 10 is perforated through luminous circular hole 4 to outer；The control flume is set respectively on the outside of 8 four jiaos of ends It is equipped with installation screw 7, cover board 6 is twisted in precession installation screw by screw and is fixed on control flume 8；6 surface lower portions of cover board It is provided with through-hole, button switch 9 is inserted through through-hole to outer.

Preferably, the quadrangle end of the mainboard 1 is arc-shaped to one kind as the utility model, which is white Acrylic board, the mainboard 1 are 18 × 22cm with a thickness of 8mm, the length and width of mainboard 1.

Preferably, the handle is 4 × 9cm with a thickness of 8mm, the length and width of handle to one kind as the utility model.

Preferably, the dominant eye peep hole 2 is circle, the hole of the dominant eye peep hole 2 to one kind as the utility model Diameter is φ 25mm.

Preferably, the aperture of the luminous circular hole 4 is φ 1mm to one kind as the utility model.

One kind as the utility model is preferably arranged on four installation screws on the outside of 8 four jiaos of ends of the control flume Rubber washer, the Zhou Changwei 18cm of rubber washer play sealing and buffer protection.

Preferably, the button cell 11 is model C R2032, the button electricity that voltage is 3V to one kind as the utility model Pond.

The working principle of the utility model number is as follows:

In the design, main board material is using white acrylic board, and with a thickness of 8mm, main board length and width are 18*22cm, Grip size below mainboard is 4*9cm.

The design first sprays black paint in production, and mainboard center is the circular hole of a diameter 2.5cm, is observed with for dominant eye Hole；The bottom of mainboard is provided with handle, and mainboard surface lower portions centre is the aperture of a diameter 1mm, which is the circular hole that shines, The mainboard back side is provided with LED lamp bead, and the LED lamplight issued penetrates aperture.One white point of label, white at the 4mm of aperture two sides Dot shape is circle, and then one white point of label, aperture two sides correspond to 11 white points of each label at 8mm.It is small at two White point centre successively marks from center to two sides and goes up number 2,4,6,8,10,12,14,16,18,20,22, between two numbers Distance be also 8mm.

In the design, dominant eye peep hole design principle: when detected person watches objects ahead attentively by peep hole, usually Think it oneself is that eyes are look at objects ahead, but actually only have one eye to be look at objects ahead by peep hole.Optometry When teacher blocks left eye and right eye respectively, it finds that being look at target at a glance, another eye is look at baffle, it was demonstrated that object observing Eyes are dominant eye.

As illustrated in figs. 5-7, in the design, heterophoria instrument design principle is closely used: in the world, it is specified that 1cm/m=1 is 1 rib Mirror degree indicates directional light in 1 meter of local deviation 1cm.So we devise when checking at 40cm before eyes, if lines Offseting by 4mm is 4mm/40cm=1, if lines offset by 8mm, as 8mm/40cm=2.The rest may be inferred, when right eye is put When setting horizontal geneva bar, by brighten the hair luminous point.Right eye is it is seen that a vertical lines, and right eye is it is seen that a luminous point. When line is overlapped with point, for position of looking straight, without horizontal heterophoria, when on the right of line offset, i.e., ipsilateral property is watched attentively, is esophoria, is worked as line It is intercrossing outer heterophoria when deviating the left side.

As illustrated in figs. 8-9, if lines are located at the position on the right 8, as 8 esophorias, if lines are located at the left side 6 On 8 intermediate point, as 7 outer heterophorias.

As shown in figs. 10-11, similarly: when right eye places vertical geneva bar, measuring instrument is first deflected 90 ° by us, i.e., Customer is placed across at the moment at 40cm, by luminous point, when one horizontal lines that right eye is seen at this time, right eye it is seen that One luminous point.When line is overlapped with point, for position of looking straight, without horizontal heterophoria, when line is located at the top of luminous point, under right eye Heterophoria.If lines are located on luminous point 2 position, the as lower heterophoria of right eye 2, if lines be located at the lower section 0 of luminous point ~ When on 2 central white point, as heterophoria on right eye 1.

It is one 5 × 8.5cm below the dominant eye peep hole at the mainboard back side, with a thickness of the white acrylic of 8mm in the design Cover board is fixed on upper plate with four screws, and in the outside of four screws in the centre of two pieces of Asia gram side plates, placement one is circular Rubber washer increases the battery lighting system inside sealing performance and buffer protection, from squeezing.Inside two pieces of acrylic boards, The recess slot position (control flume) for being 4mm in mainboard setting depth, is used for placing battery luminescent system.

In the design, battery lighting system includes the button cell of two model CR2032 3V, button switch, LED light Pearl, button switch, LED lamp bead series connection, the button cell of two model CR2032 3V connect to form battery pack, button switch, LED lamp bead passes through conducting wire respectively and is electrically connected with the positive and negative plate of battery pack, forms integrated circuit；Button press switchs to control LED light Pearl electrified light emitting and closing.

A kind of nearly heterophoria measuring instrument described in the utility model, it installs peep hole using mainboard surface middle part, Mainboard surface lower portions are provided with luminous point and luminous point two sides are correspondingly arranged on equidistant detection white point；It, which has, uses Convenient, it is convenient to operate, and speed is fast, at low cost, can facilitate between optist and patient and link up, and guarantees optometry effect and quality.

The above description is only a preferred embodiment of the present invention, therefore all according to described in the utility model patent application range The equivalent change or modification done of structure, feature and principle, be included in the scope of the utility model patent application.
