Detailed Description

In order to make the technical solutions of the present invention better understood and implemented by those skilled in the art, the present invention is further described with reference to the following specific examples, which are provided for illustration only and are not intended to limit the present invention.

As shown in fig. 1-4, the simple synoptophore with open rotating arm and dynamic display target adopts a non-power supply design, and comprises a host 1, a rotating arm, a target system 4 and an eyepiece 12, wherein the rotating arm comprises a left rotating arm 2 and a right rotating arm 3, and the left and right rotating arms are open designs using natural light or external light sources. The open design means that the common rotating arms 3 of the homography machine are all closed lens cones, no light can enter the lens cones, the sighting target is irradiated by a light emitting source in the lens cones, and the open design means that the lens cones which are not completely closed do not exist, and the sighting target can be irradiated by natural light.

The sighting mark systems 4 are respectively arranged at two sides of the tail ends of the left rotating arm 2 and the right rotating arm 3; the eyepiece 12 is arranged at the inner side of the left rotating arm 2 and the inner side of the right rotating arm 3 and close to the rear position, and the front end of the rotating arm is provided with an eyepiece seat convenient to mount and take down and a reflector 9 forming an angle of 45 degrees with the eyepiece 12 lens. The eyepiece 12 is arranged in the oblique front of the reflector 9, and the patient watches the sighting target system 4 at the tail end of the rotating arm reflected by the reflector 9 through the eyepiece 12.

A left arm locking button 7 and a right arm locking button 8 are respectively arranged on two sides in front of the rotating arm and used for locking the rotating arm; host computer 1 left and right sides is equipped with left arm knob 10 and right arm knob 11 respectively left arm knob 10 and right arm knob 11 homonymy all are equipped with interpupillary distance adjusting knob 6 by preceding position. The pupil distance adjusting knob 6 is arranged in the host 1, a pupil distance scale and a dial are arranged on the host 1, and the lower jaw support 5 is arranged on the back side of the host 1.

The visual target system 4 has a vertical slot, and can be inserted into the corresponding same group of visual target images, such as: the same group of simultaneous visual target, fusion visual target or stereo visual target.

The sighting target system 4 can adopt a liquid crystal screen to display images, and the liquid crystal screens in the left rotating arm and the right rotating arm synchronously display the same group of sighting target images, such as: the same group of simultaneous visual target images, the same group of fused visual target images or three-dimensional visual target images.

The working principle of the invention is as follows:

the rotary knobs 10 and 11 are rotated by rotating the rotary arms on the host machine 1, so that the left rotary arm and the right rotary arm 2 and 3 synchronously rotate, or one of the rotary arms is locked to rotate the other rotary arm, so that the sighting target image in the sighting target system 4 is watched through the ocular 12, and the sighting targets watched by two eyes are simultaneously viewed, fused and stereoscopically viewed. The rotating amplitude of the left and right rotating arms is observed through a dial on the host 1 to judge the treatment effect.

The simple synoptophore is a portable training device for recovering visual function of two eyes and improving amblyopia vision. The principle of reflecting the projected object image by the reflector is adopted, and the precision of the instrument is ensured by accurately calculating the structural angle and strict process flow. Structurally, key components and functions of a traditional synoptophore are reserved, the sighting target system adopts a computer system to display images through a liquid crystal screen, static images of the traditional synoptophore can be controlled through software, dynamic animation images are generated (namely sighting target images which can synchronously display a group of one-to-one correspondence on two liquid crystal screens), and therefore the image enrichment degree and interestingness are enhanced, compliance is improved, and the treatment effect is improved.

The vision training software distinguishes the visual fields of the two eyes through the left rotating arm and the right rotating arm, so that the two eyes watch the same group of image sighting marks of three types of simultaneous vision, fusion and stereoscopic vision at the same time.

The simultaneous vision image adopts completely different figures, so that the inhibition areas of the normal retina corresponding to the eyes of the patient are forced to simultaneously receive stimulation, the simultaneous vision function of the inhibition areas of the retina is recovered, and the function of eliminating inhibition and recovering the simultaneous vision of the eyes is achieved. According to the size of the sighting target displayed on the liquid crystal screen, the sighting target can be divided into a peripheral macular type 10 degrees, a peripheral macular type 5 degrees and a central concave type 3 degrees;

the fusion image is composed of a pair of identical figures, but each figure is provided with a control point or a contrast point, so that two objects are continuously separated and aggregated to achieve the purpose of improving the fusion function. The picture can be divided into a peripheral control point, a central control point and an upper control point and a lower control point according to the position of the control point;

the stereoscopic vision image is a special fusion sighting target. Certain separation positions are kept between the patterns of the two eyes, image information with the position difference of the two eyes is formed, stereoscopic vision stimulating tasks with different parallaxes are generated, training of the stereoscopic vision stimulating tasks from scratch to scratch and from easiness to difficulty is carried out, and the purpose of improving the stereoscopic vision function is achieved.

In addition, the invention adopts the design without a power supply, and the rotating arm adopts an open structure, thereby reducing the production cost, bringing lower price than the traditional synoptophore, greatly improving the cost performance, and being particularly suitable for families and professional institutions.

The details of the present invention not described in detail are prior art.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
