Problems solved by technology

[0003] The traditional vision training method is generally to wear prisms for binocular vision training, but there are currently difficulties in the selection of prism degrees during vision training
Because if the vision training prism degree is equal to the strabismus prism degree, although the patient feels relatively comfortable subjectively, the eye muscles maintain a large strabismus state, and it is not easy to change the strabismus degree through training, resulting in poor training effect; an

Embodiment 1

[0068] Such as figure 1 As shown, a strabismus training device disclosed in this embodiment includes a display module, an image capture and processing module 105, a calibration module, an eye movement point analysis module, and a strabismus training image displacement range calculation module. It also includes an electronic computer, and the image processing algorithm, calibration module, eye movement point calculation module, and eye movement point analysis module of the image capture and processing module 105 are all programs running on the electronic computer. In order to further improve the clarity of the image captured by the image capture and processing module 105 and reduce eye movement test errors caused by head movement, a head fixation bracket 104 is used for head fixation in this embodiment.

[0069]In this embodiment, the display module is a polarization display 101 that can emit two kinds of polarized light, and two polarizers used in conjunction, a left polarizer...

Embodiment 2

[0109] Display module, image shooting and processing module, calibration module, and eye movement point analysis module are the same as embodiment one in the present embodiment, because the strabismus direction and strabismus prism degree of known patient, calculate strabismus training in the strabismus training image displacement range calculation module There is a difference in the way the image shifts the range. In this embodiment, it is known that the strabismus direction of the patient is right eye exotropia, and the strabismus prism degree L of the strabismus eye 0 It is 15 prism degrees; and the distance between the eyes and the display module is known to be Z 0 , Z in this example 0 It is 60cm. Specifically, the displacement range of the squint training image is calculated through the following steps:

[0110] (a) Display image 1 that is only visible to the left eye in front of the subject, and the image 1 is visual mark A, and let the testee focus on the visual mar...

Embodiment 3

[0116] In addition to the device designed in Embodiment 1, the display module, image capture and processing module of the present invention can also adopt the following methods:

[0117] (one)

[0118] The display module includes a polarized display that can emit linearly polarized light, and the polarized display can emit linearly polarized light in the horizontal direction, and can also emit linearly polarized light in the vertical direction. The display module also contains two polarizers, where the left polarizer is located between the left eye and the polarized display, and the right polarizer is located between the right eye and the polarized display; the left polarizer can transmit linearly polarized light in the horizontal direction, but not vertically linearly polarized light in the horizontal direction; the right polarizer can pass through linearly polarized light in the vertical direction, but not linearly polarized light in the horizontal direction; when the displa...

Abstract

The invention provides a strabismus training device. The strabismus training device is characterized by comprising a display module, an image shooting and processing module, a calibration module, an eye movement point calculation module and a strabismus training image displacement range calculation module, or a strabismus training prism degree range calculation module, wherein the image shooting and processing module includes at least one camera, and can continuously shoot images of the left eye and the right eye; and the calibration module is used for performing single-eye calibration on the left eye and the right eye. The strabismus training device has the beneficial effects: on the basis of keeping fusion of both eyes, the strabismus degree is gradually reduced by performing visual training on a strabismus patient, and the effect of treating strabismus without an operation is achieved.

Description

technical field [0001] The invention relates to the field of ophthalmic medical devices, in particular to a strabismus training device. Background technique [0002] Strabismus is a common disease in ophthalmology. The treatment of strabismus is mainly surgical treatment and visual training at present. Generally speaking, patients with strabismus can try visual training first. If they can return to normal through visual training, the physical and mental pain caused by surgery can be avoided, and the possible side effects of surgery can also be avoided. [0003] The traditional vision training method is generally to wear prisms for binocular vision training, but the choice of prism degree in vision training is currently difficult. Because if the vision training prism degree is equal to the strabismus prism degree, although the patient feels relatively comfortable subjectively, the eye muscles maintain a large strabismus state, and it is not easy to change the strabismus deg...
