Abstract
The utility model discloses a dual-functional nearsightedness preventing instrument, which comprises a basic frame worn on the head. The basic frame is provided with a brightness detecting and alarming device and a head posture detecting and alarming device; on one hand, when the brightness of a learning environment is lower than set standard brightness, the brightness detecting and alarming device processes brightness signals and sends out a hint which reminds a user to adjust the light intensity of the environment; and on the other hand, when the user is in an improper reading and writing posture, i.e. eyes are too close to books and the neck region is too crooked, the balance of the head posture detecting and alarming device changes, and then a loop of the head posture detecting and alarming device is closed to send out a hint which forewarns the user to adjust the reading and writing posture. The dual-functional nearsightedness preventing instrument has dual functions, i.e. brightness detection and reading and writing posture detection, is suitable for preventing nearsightedness, and has small volume and simple equipment; and learning and preventing can be carried out simultaneously, so that separate treating time is not needed, and the instrument is convenient to use and is convenient to popularize.
Description
Technical field
The utility model relates to a kind of instrument of pre-myopia prevention.
Background technology
At present, the adolescent myopia rate rapidly rises, and reads a book, writes, sees TV for a long time, will feel that eyes are dry and astringent, eyelid is heavy, and eye socket pain, blurred vision are then expanded in eyeball acid, slur appears, reading serial, symptom such as serious giddy, headache also may occur, feel sick.Myopic people is not except seeing distant objects, and majority also is easy to generate asthenopia.Sometimes in order to see font clearly, myopic people like books put very near apart from eye, so more increased the weight of the burden of eye, cause myopia to be aggravated.And for the teenager because near-sighted blurring of vision, tend to cause absent minded on class, thereby influence school grade, endanger extremely serious.Myopia is studied carefully its induced factor and mainly contained: the read-write attitude is improper, and the brightness of read-write ambient light is insufficient.
The utility model content
Technical problem to be solved in the utility model provides a kind of the have luminance brightness of detection and read-write attitude dual-use function, be applicable to pre-myopia prevention, volume is little, equipment is simple, study and prevention can be carried out simultaneously, do not need independent treatment time, easy to use, the difunctional myopia preventer of being convenient to promote.
For solving the problems of the technologies described above, the technical solution of the utility model is: difunctional myopia preventer, comprise the pedestal that is worn on head, and bright detection alarm device and head pose detection alarm device are installed on the described pedestal.
As optimized technical scheme, described bright detection alarm device comprises that light detects the unlatching switch, described light detects the unlatching switch and is electrically connected with photoresistance, described photoresistance is electrically connected with the comparison integrated circuit, the described relatively signal output part of integrated circuit is electrically connected with switch triode, and described switch triode is electrically connected with light emitting diode.
As to improvement of the technical scheme, described head pose detection alarm device comprises that attitude detection opens switch, and described attitude detection is opened switch and is connected with mercury cut-off, and described mercury cut-off is electrically connected with the sounding suggestion device.
As to further improvement in the technical proposal, described pedestal is a spectacle frame.
As to further improvement in the technical proposal, described pedestal is glasses.
Owing to adopted technique scheme, difunctional myopia preventer comprises the pedestal that is worn on head, and bright detection alarm device and head pose detection alarm device are installed on the described pedestal; On the one hand, when the luminance brightness of academic environment drops to when Benchmark brightness is set, described bright detection alarm device is handled bright signal, sends prompting, reminds the user to adjust the light intensity of environment; When user's attitude is good on the other hand, described head pose detection alarm device is in initial equilibrium conditions, the loop of described head pose detection alarm device is an off state, improper when the read-write attitude, eyes are crossed when near from books, and incidence is flexing too, described head pose detection alarm device balance changes, the circuit closed of described head pose detection alarm device sends prompting, and the caution user adjusts writing gestures; The utlity model has and detect luminance brightness and read-write attitude dual-use function, be applicable to pre-myopia prevention, volume is little, and equipment is simple, and study and prevention can be carried out simultaneously, do not need independent treatment time, and be easy to use, is convenient to promote.
