Anti-myopia head wear type device

Abstract

The invention relates to the technical field of electronic information and optical, electrical and mechanical integration, and provides an anti-myopia head wear type device which is capable of monitoring eye using conditions and warning a user to urge the user to use the eyes correctly when poor eye using conditions occur. The anti-myopia head wear type device aims to solve the problems that the user cannot monitor the brightness of an eye using environment, the stability of eye balls, an eye using distance and time for using the eyes in a short distance. According to the anti-myopia head wear type device, an eye using monitoring and warning device is embedded in a head wear piece (such as eye glasses, a tiara, a head ring, a head band and a cap), when the anti-myopia head wear type device is used, the anti-myopia head wear type device maintains a stable relation with the eyes, sensors are used for monitoring the eye using conditions, obtained information is operated through a central processing unit, when the eye using distance is too short, or time is too long, or light rays are too bright or too dark, or the eye balls are instable, warning signals are given out, through electro-optic conversion, electro-acoustic conversion and electro-mechanical conversion, light, sound and vibration are utilized to remind the user to correct, the user can use the eyes correctly, and the purposes of reducing eyestrain and preventing myopia are achieved.

Description

technical field [0001] The present invention mainly relates to a head-mounted device for preventing myopia that monitors eye distance, time, brightness, head stability and warns when eye hygiene is poor, in the field of electronic information technology and optoelectronic integration technology. Use ophthalmopathy to achieve the purpose of reducing eye fatigue and preventing myopia. Background technique [0002] When the normal eye looks at a distant object, the ciliary muscle of the eye relaxes, the suspensory ligament of the lens contracts, the lens becomes thinner, and the distant object is imaged on the retina; when looking at a near object, the ciliary muscle contracts, the suspensory ligament of the lens relaxes, and the lens becomes thinner thick, near objects are imaged on the retina. Under normal circumstances, the eyes have an automatic adjustment function. If the reading distance is too close or the reading time is too long, the ciliary muscle spasms and cannot r...

Problems solved by technology

[0007] In order to solve the problem that the eye user cannot consciously and actively self-monitor the state of the eye at any time (such as eye distance, time, ambient brightness and eyeball stability), the present invention monitors the state of the eye through a sensor, and transmits the obtained information to the central processing unit. device, process the monitored data, make suggestions according to the built-in expert system and output warning signals, through electro-optic, electro-acoustic, and motor conversion, apply light, sound, and vibration when the user's eye distance is too close, the time is too long, the light Warn the user when it is too bright or too dark, and the eyeballs are shaking, correct the user's eye-using mistakes, and make them use the eyes correctly, so as to reduce eye fatigue and prevent myopia
