Embodiment Construction

[0030] In order to minimize eye fatigue when looking at close objects, you should maintain a proper viewing distance (greater than 50cm). It is best to place the sight at 0.7m to 2.5m in front of the human eye, and look at the same object with the left and right eyes. The images seen by the two eyes are as consistent as possible, or the difference is not more than 5% (Ophthalmology believes), of course, the fatigue caused by this refractive imbalance is very obvious for monocular work; the human eye work is kept in the first At one eye position, the extraocular muscles are in a cooperative working state at this time, and the sight falls within the range of ±26 degrees in front of the human eye. Single eye is -10 degrees to 26 degrees. When the eye is looking at infinity ahead, the eyeball is horizontal. The axis is inclined by 13 degrees, and the upper edge of the sight or image is aligned with or below the horizontal line of sight of the human eye; maintain a certain vertical vie...

Abstract

The disclosed method to prevent fatigue when wearing glass-type display comprises: letting the top edge of system image level or lower than people horizontal sight line, and keeping the included angle alpha between horizontal sight line and image normal line in -25~-10deg, wherein the device comprises: a body 1 with front/back shell 11/12, a left/right lens root 6/5, a glass frame 4, a PCB 2, an image display module 3, a glass interface 61 connected with input end of PCB 2 and external signal, an image wafer 3 connected with output of 61, a window plane 121 behind 12, and a nose frame 7. This invention has benefit for people health.

Description

Technical field [0001] The present invention relates to a method for preventing visual fatigue from wearing a head-mounted glasses display, and a head-mounted glasses display that realizes this method. The latter particularly refers to a type including a front shell and a rear shell, the front shell and the rear shell A housing is formed, a mirror frame and a circuit board are built in the housing, an image display module is arranged at both ends of the mirror frame, the output end of the circuit board is connected with the image display module, and the input end is connected with an input signal; the housing A head-mounted glasses display with the body and the glasses wearing mechanism connected. Background technique [0002] As we all know, the eye is composed of the eyeball, optic nerve and optic pathway, and eye appendages. The eyeball includes the eyeball wall, eye cavity and contents, nerves, blood vessels and other tissues. From the outside to the inside, there are the cor...
