Embodiment Construction

[0030] In order to minimize eyesight fatigue when watching near objects, an appropriate viewing distance (greater than 50cm) should be maintained. It is best to place the viewing object 0.7m to 2.5m in front of the human eye, and the left and right eyes see the same object. The images seen by the two eyes should be as consistent as possible, or the difference should not be greater than 5% (in the opinion of ophthalmology). At one eye position, the extraocular muscles are in a coordinated working state at this time, and the visual object falls within the range of ±26 degrees in front of the human eye, and the single eye is -10 degrees to 26 degrees. Each axis is inclined outward by 13 degrees, and at the same time, the upper edge of the visual object or image is flush with the horizontal line of sight or below the human eye; maintain a certain angle of view in the vertical direction, avoid strong reflection glare from the external environment and do not let the light directly hi...

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. Thisinvention has benefit for people health.

Description

technical field [0001] The present invention relates to a method for preventing eyestrain from wearing a head-worn glasses display, and a head-worn glasses display for realizing the method, the latter particularly refers to a method comprising a front shell and a rear shell, the front shell and the rear shell A shell is formed, and a mirror frame and a circuit board are built in the shell, and 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 externally connected with an input signal; the shell A head-mounted glasses display whose body is connected with a glasses wearing mechanism. Background technique [0002] As we all know, the eye is composed of three parts: eyeball, optic nerve and optic pathway, and ocular appendages. The eyeball includes the eyeball wall, the inner cavity of the eye and its contents, nerves, blood vessels and other tissues. From th...
