Problems solved by technology

[0003] In view of the defect that the existing glasses are difficult to keep the object distance stable, the technical problem to be solved by the glasses device for viewing the display screen of the present invention is: use the glasses to zoom out the object image to relax the adjustment and collection of the eyes, and control the display screen and the glasses by using the bracket. The distance between the virtual image on the display screen and the glasses is controlled by the distance between them, so as to achieve the effect of stabilizing the image distance, stably relaxing the adjustment and concentration of the eyes, improving the observation effect, making the observer feel comfortable and less prone to fatigue

Embodiment 1

[0067] Embodiment 1: A kind of glasses device for viewing display screen, such as figure 1 Shown, 1 is glasses, and 2 is the support that controls the distance between glasses and the display screen, and 3 is the special component (connected with screw) of connecting display screen device, and 4 is the display screen. Loosen the fixing member (screw) 5 on the telescopic sleeve type bracket 2 to adjust the position of the glasses or the display screen, and adjust the bracket 2 to make the distance between the glasses and the display screen equal to "1.1 x the focal length of the glasses ≥ the glasses and the display screen Any value within the distance between the distance ≥ the focal length of the glasses ÷ (the focal length of the glasses + 1)". Tightening the screw 5 can fix the distance between the glasses and the display screen. The 7th, can be worn on the head and watch the cap type support bracket. 9 is the main frame (or computer or controller etc.) of display, and 1...

Embodiment 2

[0075] Embodiment 2: A kind of glasses device for viewing display screen, such as Figure 24 Shown, 1 is glasses, and 2 is the support that controls the distance between glasses and the display screen, and 3 is the special component that connects display device (the display screen can be connected with screws at 3 places). Loosen the fixing screws 5 at different positions on the telescopic sleeve type bracket 2 to adjust the position of the glasses 1 or the special component 3 connected to the display device, and tighten the screws 5 to fix the gap between the glasses 1 and the empty position where the display device can be placed. distance. 7 is a head-mounted support base. 8 is the "center-shifting positive lens" in the glasses, and 6 is the lens holder in the glasses. The glasses are composed of two symmetrical "center-shifting positive lenses" 8 and 8, and a lens holder 6. The structure of the glasses can be one of the various glasses described in Embodiment 1. Compare...

Embodiment 3

[0077]Embodiment 3: A kind of glasses device for watching the display screen, as shown in Figure 30, consists of glasses 1 for viewing the display screen, a bracket 2 for controlling the distance between the glasses and the display screen, and a display on the bracket for connecting The special component 3 of the screen device is composed. The lens structure of the glasses 1 can be any one in Embodiment 1. The glasses can relax the adjustment and collection of the eyes at the same time, and the real focus formed after the parallel light passes through the lens facing the left eye in the glasses and passes through the lens facing the right eye The distance between the formed real focal points is less than 0.035 meters, and the left and right lenses of the corresponding eyes are symmetrical. "Special component for connecting a display device" 3 is a kit with grooves on three sides. The "special component for connecting a display screen device" 3 can be sleeved on the liquid cry...

Abstract

The invention provides a glass device for watching a display screen and relates to the technical field of glasses. The glass device for watching a display screen is provided with a bracket which can control the distance between the glasses and the display screen; one end of the bracket is provided with the glasses which can relax the adjustment and focusing of eyes; and the other end of the bracket is provide with the display screen or only a special component used for connecting or mounting the display screen device. The glass device solves the following technical problems: relaxing the adjustment of the eyes by making use of a far objective image of the glasses; and controlling the distance of the virtual image of the display screen and the glasses by controlling the distance between the glasses and the display screen through the bracket so as to achieve the aims of improving the observation effect, stably relaxing the adjustment and focusing of eyes, and making an observer feel comfortable and not fatigable. The glass device for watching the display screen can be used for preventing myopia or treating pseudomyopia.

Description

technical field [0001] The invention relates to the technical field of glasses. Background technique [0002] Watching the nearby display screen requires the use of the adjustment function of the eyes, and the tension of the adjustment will make the eyes tired. Wearing the positive lens glasses of the prior art (such as "prism type presbyopic glasses" patent No. ZL200620031493.6) to watch the nearby display screen can relax the adjustment of the eyes, but its disadvantage is that the distance between the glasses and the display screen cannot be well controlled. distance between. According to the optical formula 1 / u+1 / v=1 / f, it can be seen that the change of the distance u between the glasses and the display screen will change the virtual image distance v between the glasses and the display screen, because the observer's activities will inevitably change the observation frequently unconsciously. The position of the observer's eyes often changes the distance between the glas...
