Problems solved by technology

Its shortcomings are that the operation of the instrument is more complicated, and the training content is a single static picture, which is not very interesting. It is difficult for patients, especially children, to maintain long-term concentration, and it is difficult to objectively and quantitatively judge the state of binocular vision training of patients.

Embodiment 1

[0057] like figure 1 As shown, a visual detection and visual training device disclosed in this embodiment includes a display module, an image capturing and processing module 105, a calibration module, an eye movement point calculation module, and an eye movement point analysis 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.

[0058] 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 a right...

Embodiment 2

[0103] 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)

[0104] The display module includes a polarized display that can emit circularly polarized light, and the polarized display can emit left-handed circularly polarized light and can also emit right-handed circularly polarized light. 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 left-circular polarized light, but cannot transmit right-circular polarized light. Polarized light; the right polarizer can transmit right-handed circularly polarized light, but not left-handed circularly polarized light; when the display device displays an image composed only of left-handed circularly polariz...

Embodiment 3

[0111] In addition to visual training in fixed places such as hospitals and homes, in order to allow patients to perform visual training and effectively monitor binocular vision status in actual daily life, a head-mounted visual inspection and visual training device can be used. include:

[0112] The left eye visual axis measurement module can measure the visual axis of the left eye. In this embodiment, two miniature infrared cameras and two near-infrared LEDs are installed on the frame to capture the left eye. The binocular vision principle can be used to measure the positions of the two near-infrared corneal reflection points and calculate the position of the left eye corneal spherical surface. The three-dimensional space position of the center of the sphere can also measure the three-dimensional space position of the pupil center of the left eye. The line connecting the three-dimensional space position of the center of the sphere where the corneal sphere is located and the ...

Abstract

The invention provides a visual detection and visual training device, which is characterized by comprising: a display module; an image capturing and processing module; a calibration module; an eye movement point calculation module; and an eye movement point analysis module. Another technical solution of the present invention is to provide a head-mounted visual inspection and visual training device. The present invention has the beneficial effects that monocular vision and binocular vision can be trained at the same time, and doctors can objectively judge the state and effect of binocular vision training through eye movement data. In addition, the training content can be in various forms such as pictures, videos, animations, games, etc., and can interact through sight lines, which improves the fun of the training, improves the initiative of the patient training, and is conducive to achieving a better visual training effect.

Description

technical field [0001] The present invention relates to the field of ophthalmic medical instruments, in particular to visual detection and visual training equipment for binocular vision. Background technique [0002] Binocular vision is divided into three levels: the first level is simultaneous vision, the second level is fusion vision (also called "fusion function", or "planar fusion"), and the third level is stereopsis (also called "stereoscopic vision"). vision"). Simultaneous vision refers to the signals transmitted to the brain from the retinas of both eyes, not received alternately by both eyes, but received simultaneously. Fusion vision is based on the simultaneous vision of both eyes, the brain center synthesizes the object images falling on the retinas of both eyes into a complete object image. Stereoscopic vision is a relatively independent visual function with three-dimensional space on the basis of the above two-level visual functions. For the rehabilitation t...
