Embodiment 1

[0024] Embodiment 1, as figure 1 , figure 2 and image 3 As shown, a single-screen head-mounted display composed of a mirror frame 101, a mirror frame front cover 105, a mirror frame rear cover 102, an eyepiece 104, a mirror back 103, and a display screen 107, the display screen 107 is a high-definition widescreen display screen, and the eyepiece 104 is an aspheric lens with anti-blue light function. The high-definition digital camera 106 is installed on the spectacle frame front cover 105 and is located in the middle of the display screen 107. The object angle of view seen by the present invention is the same as that seen by naked eyes. Two identical images on the left and right are displayed on the full screen with the left and right middle lines of the display screen as the boundary. The center point corresponds to the center point of the left and right image screens on the display (the line connecting the center points of the left and right eyepieces and the center poi...

Embodiment 2

[0025] Embodiment 2. This embodiment is basically the same as Embodiment 1, except that the interpupillary distance is adjustable. To adjust the interpupillary distance, you need to adjust the screen interpupillary distance and the eyepiece interpupillary distance, and keep them equal. Use software to change the width of the image display window on the display screen to adjust the interpupillary distance of the screen (the principle and method are the same as the adjustment of the interpupillary distance of the existing single-screen VR product screen). Built-in image window width adjustment program, adjust the width of the image display window by reducing or increasing the adjustment key, each time the adjustment key is pressed, the width of the image display window decreases or increases by 2mm, and the interpupillary distance decreases or increases by 1mm . For example, in the case of full-screen display of the left and right images (screen pupil distance is the largest), ...

Embodiment 3

[0026] Embodiment 3, this embodiment is basically the same as Embodiment 1 and 2, the difference lies in the way of wearing them. Battery 109, power switch and external power socket are all installed on the mirror frame 101, as Figure 7 As shown, the two ends of the spectacle frame 101 are connected with an elastic headband 401, and there is an adjustment buckle 402 in the middle of the headband for adjusting the length of the headband, which is worn in a headband style.

Abstract

The invention discloses single-screen 2D anti-myopia digital glasses. A digital camera is installed on the front of a single-screen head-mounted display, and is located in the center of a display screen, an image captured by the digital camera is displayed into two left-right same images with a left-right middle line of the display screen as a boundary, a selfsame image is seen through a left eyeand a right eye of eye lenses respectively if distance between the interpupillary distance and a frame center point of the left image and a frame center point of the right image is same, and a naturally-coincided 2D image is seen through the two eyes. The single-screen 2D anti-myopia digital glasses are used for indirectly seeing objects, close-distance object seeing is converted into infinite-long-distance object seeing visually, occurrence of myopia can be effectively prevented from disease causes, and recovery of pseudomyopia is promoted; the left-eye image and the right-eye image are displayed on one display screen, the bright degrees, the contrast degrees and colors of the left-eye image and the right-eye image are completely same, the good visual effect is achieved, and the single-screen 2D anti-myopia digital glasses are simple in structure, easy to manufacture and convenient to use and carry.

Description

technical field [0001] The invention relates to glasses, in particular to 2D digital glasses. Background technique [0002] There is a certain distance between the two eyes of a person. When viewing an object, it is like two cameras with a distance of about 6cm to shoot the same object and capture two images with different left and right positions. The human brain has the ability to fuse two images with different positions. together so that objects can be seen clearly while gaining a sense of three-dimensionality. When the same object is nearsighted, the left and right positions of the image of the object seen by the left and right eyes are very different, and the brain needs a large fusion force to complete the fusion. . The eyes have the ability to adjust, and the adjustment force generated by the contraction of the eye muscles when viewing objects at close distances presses the left and right eyeballs to converge toward the middle of the two eyes, and uses the near-pupi...
