Abstract
The utility model discloses myopia prevention glasses, which comprise two lenses and a frame. The frame is provided with a buzzer (5), a distance detecting infrared sensor (4), a rotary switch (3), a power supply switch (1) and a power supply module (2) for supplying power. The infrared sensor (4) comprises an infrared receiving tube, an infrared transmitting tube and a sliding rheostat, the rotary switch (3) is connected with the sliding rheostat to adjust the threshold of a distance detected by the infrared sensor (4), the buzzer (5) is connected with the infrared sensor (4), and operation of the buzzer (5) is controlled according to the distance detected by the infrared sensor (4). A safe distance can be maintained between the eyes of a user and a book, the eye health can be ensured, the eyesight can be protected, and myopia can be prevented.
Description
Technical field
The utility model discloses a kind of glasses, thereby more specifically say so a kind of glasses that utilize the pre-myopia prevention of infrared detection distance reminds people.
Background technology
The teenager is faced with enter a higher school pressure and social competition's pressure, and present teenager's more time is used in the face of books and computer.Long-time cause easily and use kopiopia, yet be to cause near-sighted main cause with kopiopia in the face of books and computer.Junior middle school according to investigations, senior middle school, university student's myopia incidence of disease are respectively 20.23%, 48.18% and 73.01%.Myopia has caused far-reaching influence to teen-age study, life.
At present, domestic possessed the technology that laser is corrected defects of vision, but the later stage that laser is corrected influence is unknown.And the laser corrective procedure has certain risk.Country advocates students in middle and primary schools and adheres to doing eye exercises every day, but seldom has the student consciously to adhere to getting off.
Discover, keep the suitable distance of eyes and books in the read-write process, effective remitting vision fatigue, vision protection.Now the anti-myopia glasses on the market is to correct myopia by eyeglass mostly, still lacks a kind of glasses of can automatic range reporting to the police.
The utility model content
The technical matters that the utility model solves provides the glasses of a kind of energy infrared ray sensor automatic range prompting user's pre-myopia prevention.
For solving the problems of the technologies described above, the glasses of a kind of pre-myopia prevention of the utility model comprise eyeglass and picture frame, the power module that this picture frame is provided with hummer, is used to detect the infrared ray sensor of distance, rotary switch, power switch and is used to power; Infrared ray sensor comprises that infrared receiving tube, infrared transmitting tube and slip become resistance; Rotary switch links to each other with the change resistance of sliding, and is used to regulate the distance threshold that infrared ray sensor detects; Hummer links to each other with infrared ray sensor, by the work of the detected distance value control of infrared ray sensor hummer.
Further, in the glasses of a kind of pre-myopia prevention of the utility model, infrared ray sensor is positioned at the center position of picture frame.
Further, in the glasses of a kind of pre-myopia prevention of the utility model, distance range 2 ~ 50CM that infrared ray sensor detects.
Further, in the glasses of a kind of pre-myopia prevention of the utility model, power module adopts the 5V lithium battery.
The utility model compared with prior art has the following advantages: the user uses anti-myopia glasses in the study and work process, can keep good sitting position so that keep suitable distance between eyes and the books, guarantees to use eye healthy, vision protection, pre-myopia prevention.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the glasses of a kind of pre-myopia prevention of the utility model.
Fig. 2 is the circuit theory diagrams of the glasses middle infrared (Mid-IR) sensor of a kind of pre-myopia prevention in the utility model.
Drawing reference numeral explanation: 1 power switch, 2 power modules, 3 rotary switches, 4 infrared ray sensors, 5 hummers.
Embodiment
As shown in Figure 1, the glasses of a kind of pre-myopia prevention of the utility model comprise eyeglass and picture frame, the power module 2 that this picture frame is provided with hummer 5, is used to detect the infrared ray sensor 4 of distance, rotary switch 3, power switch 1 and is used to power; Infrared ray sensor 4 comprises that infrared receiving tube, infrared transmitting tube and slip become resistance; Rotary switch 3 links to each other with the change resistance of sliding, and is used to regulate the distance threshold that infrared ray sensor 4 detects; Hummer 5 links to each other with infrared ray sensor 4, by 5 work of infrared ray sensor 4 detected distance value control hummers.
As shown in Figure 2, power switch 1 is placed on the earpiece of the right, and the user opens or closes by power switch 1 control entire equipment.The user reconciles rotary switch 3 according to the needs of oneself the safe read-write distance is set, rotary switch 3 drives slide rheostat R1 at this moment, by changing the emissive power that swept resistance R1 can regulate infrared transmitting tube, the safe distance that infrared ray sensor 4 detections are set is 30 ~ 40CM.
Infrared ray sensor 4 is installed on the centre position of mirror holder, and the infrared transmitting tube in the infrared ray sensor 4 can only send sightless infrared light, and infrared receiving tube only produces induction to infrared light.In circuit, adopt infrared transmitting tube D2 and infrared receiving tube Q2.When infrared sensor 4 detects the user when the distance of the place ahead books is lower than 30CM, voltage drops to rapidly about 1 V, make triode Q1 end, the light emitting diode conducting, signal port S is a high level, the S port connects the hummer 5 that is positioned at mirror holder middle upper part position by NPN triode Q3, and triode Q3 conducting this moment touches hummer 5 and sends prompt tone.When the user from the distance of the place ahead book in the safe distance scope, triode Q1 conducting, the S port is a low level, triode Q3 does not sound by hummer.
After the user puts on anti-myopia glasses, turn on the power switch, built-in lithium battery provides operating voltage for entire equipment, and when user's eyes and books hypotelorism, the hummer 5 prompting user that sounds need adjust sitting posture; After user's eyes and books reached safe distance, hummer 5 quit work.This equipment can make user's eyes and books keep a safe distance, and guarantees with eye health, vision protection, pre-myopia prevention.
