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; and if the vision training prism degree is greater than If the prism degree of strabismus is too small, close to the limit of binocular vision vergence, the patient will feel very uncomfortable and prone to visual fatigue, which will have an adverse effect on the training effect; even if the vision training prism exceeds the limit of binocular vision vergence , which destroys the state of fusion, will lead to patients with diplopia or confusion, which can not achieve effective visual training effect

Embodiment 1

[0068] like figure 1 As shown, a strabismus training device disclosed in this embodiment includes a display module, an image capturing 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 capturing 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 capturing and processing module 105 and reduce the eye movement test error caused by head movement, in this embodiment, a head fixing bracket 104 is used to fix the head.

[0069]In this embodiment, the display module is a polarized display 101 capable of emitting two polarized lights, and two polarizers used together, a left polarizer 102 and ...

Embodiment 2

[0109] The display module, the image capturing and processing module, the calibration module, and the eye movement point analysis module in this embodiment are the same as those in the first embodiment. Because the strabismus direction and the strabismus prism degree of the patient are known, the strabismus training image displacement range calculation module calculates the strabismus training There is a difference in how the image shifts the range. In this example, it is known that the strabismus direction of the patient is exotropia of the right eye, and the strabismus prism degree of the strabismus eye is L 0 is 15 prism degrees; and the distance between the eyes and the display module is known to be Z 0 , in this example Z 0 is 60cm. Specifically, the displacement range of the strabismus training image is calculated by the following steps:

[0110] (a) Display image 1, which is only visible to the left eye, in front of the subject, and the image 1 is the optotype A, and...

Embodiment 3

[0116] In addition to the device designed in the first embodiment, the display module, the image capturing and processing module in the present invention can also adopt the following methods:

(one)

[0117] The display module includes a polarized display capable of emitting linearly polarized light, and the polarized display can emit linearly polarized light in a horizontal direction and can also emit linearly polarized light in a vertical direction. The display module also includes 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 cannot transmit vertical light. Linearly polarized light in the horizontal direction; the right polarizer can transmit the linearly polarized light in the vertical direction, but cannot transmit the linearly polarized light in t...

Abstract

The invention provides a strabismus training device, which is characterized by comprising a display module; an image capturing and processing module, including at least one camera, which can continuously capture images of the left eye and the right eye; The eyes are respectively calibrated by monocular; eye movement point calculation module; strabismus training image displacement range calculation module, or strabismus training prism degree range calculation module. The present invention has the beneficial effects that: on the basis of maintaining binocular fusion vision, the strabismus patient can be gradually reduced by performing visual training to achieve the effect of treating strabismus without surgery.

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 currently mainly surgical treatment and visual training. Generally speaking, strabismus patients can try visual training first, and if they can return to normal through visual training, the physical and mental pain caused by surgery to the patient and the possible side effects of surgery are avoided. [0003] The traditional visual 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 prismatic degree of vision training is equal to the prismatic degree of strabismus, although the patient feels more comfortable subjectively, the eye muscles maintain a large strabismus state, and it is not easy to change the degree of strabis...
