Description

Three-dimensional simulation amblyopia treatment instrument

Technical field

The present invention relates to amblyopia treatment apparatus, and in particular to a three-dimensional simulation amblyopia treatment apparatus. Background technique

Amblyopia is one of the most common childhood eye diseases, which seriously affects children's visual function. According to the results of the census in recent years in China, the incidence of amblyopia among adolescents and children is 3-4% higher, which means that more than 10 million children in 300 million children have amblyopia, and there is a trend of increasing year by year. Child amblyopia has become a social issue of concern.

At present, the methods of prevention and control of amblyopia commonly used at home and abroad mainly include optic correction, occlusion therapy, post-therapy, red filter therapy, optical drug suppression therapy, visual physiological stimulation, acupressure, and two-dimensional visual training. Etc. However, these treatments have a long treatment period, the treatment process is tedious, and the effect is not satisfactory. Summary of the invention

In order to overcome the shortcomings of the prior art amblyopia treatment period, the treatment process is tedious and the effect is not ideal, and the present invention provides a three-dimensional simulation amblyopia treatment apparatus.

The three-dimensional simulated amblyopia treatment apparatus provided by the invention comprises: a housing; a 3D stereoscopic display, located inside the housing; a light valve eyepiece, the light valve eyepiece comprising a left eyepiece and a right eyepiece, the left eyepiece and the right eyepiece being embedded in the a position on the housing facing the center of the display screen; a synchronization signal controller located inside the housing and electrically connected to the left and right eyepieces; and a computer device located inside the housing, The display screen and the synchronization signal controller are electrically connected, and are configured to control the left eyepiece and the right eyepiece to be alternately opened and closed by the synchronization signal controller, and control the 3D stereoscopic display to display a plurality of different motion trajectories of the three-dimensional Optotype, and control the three-dimensional optotype for appearance, One or more of the mirror, zoom in, zoom out, flicker, and move.

When using the three-dimensional simulated amblyopia treatment instrument provided by the present invention, the three-dimensional stereoscopic object is used for mirroring, mirroring, zooming in, zooming out, flickering and moving to guide the viewer's eyeball for triple motion, external rotation motion, omnidirectional motion, and pursuit. Exercise, squat track movement or sensitized focus movement, so that the viewer's eye muscles and crystals can be fully moved and adjusted, and the stimulation of the light of each color of the image can be used to treat the amblyopia.

In addition, amblyopia children generally do not have stereoscopic function. The three-dimensional simulated amblyopia treatment device provided by the present invention changes the stereoscopic vision reconstruction of amblyopia patients in the late stage of amblyopia treatment, and the three-dimensional stereoscopic image is penetrated throughout the treatment process. In the beginning of amblyopia treatment, amblyopia adolescents can perform stereoscopic vision training, which helps the visually impaired to quickly establish stereoscopic vision function. The establishment of stereoscopic vision function is very helpful to coordinate and cooperate with both eyes, which helps to correct amblyopia. The way to treat both the symptoms and the symptoms is natural and efficient. DRAWINGS

The computer device 40 can display a left eye image and a right eye image for the left and right eyes of the viewer on the 3D stereoscopic display screen 20 (the left eye image and the right eye image are a series of stereoscopic images having a certain parallax). Computer device 40 passes The sync signal controller 100 controls the left eyepiece 31 and the right eyepiece 32 to be alternately turned on and off, so that the left eye of the viewer can only see the left eye image, and the right eye can only see the right eye image, and the two images will A stereoscopic image (ie, the "three-dimensional stereoscopic object" mentioned below) is formed in the viewer's brain.

The three-dimensional optotype of the lens, into the mirror, zoom in, zoom out, flicker and move can lead the eye to triple motion, external rotation motion, omnidirectional motion, chasing motion, squat track motion or photographic focus motion. The dynamic situation of the three-dimensional stereoscopic object is described in detail below.

(1) Three-dimensional stereoscopic motion trajectory that causes the eyeball to make a triple motion

The three-dimensional stereoscopic object can be linearly enlarged over a plurality of times (for example, until the image is not closed) and linearly narrowed into the lens (for example, until the human eye is invisible), which can cause the eyeball to perform a triple motion.

Preferably, as shown in Fig. 3, the screen width is set to L.

Firstly, a three-dimensional stereoscopic object with a width of 0.01L is established in the center of the screen of the 3D stereoscopic display screen 20. The horizontal center line is the same (and always unchanged) as the horizontal center line of the screen, and the vertical center of the object in the right eye image is The line is on the right side of the vertical center line of the screen, and the distance from the vertical center line of the screen is 0.005L.

Then, the three-dimensional stereoscopic object is gradually reduced in linear proportion until its width is 0.01L, thereby simulating a far-point three-dimensional visual target.

The above-mentioned three-dimensional stereoscopic object is repeatedly repeated a plurality of times according to the above-mentioned motion trajectory, and can guide the viewer's eyeball to continuously perform the movement of looking at the near side, causing the visual triple motion, thereby causing ametropia and anisometropia. And strabismus amblyopia has a therapeutic effect.
