Detailed Description

In order that those skilled in the art will better understand the technical solution of the present invention, the following detailed description of the present invention is provided in conjunction with the accompanying drawings and embodiments.

Referring to fig. 1 and 2, the present invention provides a pair of children's myopia prevention glasses, including a glasses frame 1, two glasses lenses 2, and a sensor and timing module 9, wherein:

the left end and the right end of the spectacle frame 1 are respectively provided with a spectacle lens 2;

sensor and timing module 9 includes built-in infrared ranging sensor, time-recorder and central control unit, wherein:

the infrared ranging sensor is arranged on the outer side of the glasses frame and used for being started when a student and other users learn to detect the distance between the glasses frame and an object (such as a book, a tablet personal computer and a mobile phone) right in front of the glasses frame in real time and then sending the distance to the central control unit;

a timer installed on the glasses frame for starting when students learn, counting the continuous learning time of the users in real time and sending the time to the central control unit

The central control unit is respectively connected with the infrared ranging sensor and the timer and is used for receiving a distance value between a spectacle frame and an object right in front of the spectacle frame sent by the infrared ranging sensor in real time, comparing the distance value with a preset normal distance value (for example, 30 cm), sending a trigger alarm signal to the voice prompter module in real time when the distance value is smaller than the preset normal distance value, receiving the continuous learning time of a user sent by the timer in real time, comparing the time with a preset learning duration value (for example, 1 hour), and sending a voice playing trigger signal to the voice prompter module when the time is larger than the preset learning duration value;

and the voice prompter module is connected with the central control unit and is used for giving out a voice alarm in real time when receiving a trigger alarm signal sent by the central control unit, prompting a user to pay attention to keeping a correct learning posture, and playing a prompting voice (specifically, a pre-recorded voice segment) when receiving a voice playing trigger signal sent by the central control unit.

In the present invention, the central control unit may be a Programmable Logic Controller (PLC), a Central Processing Unit (CPU), a Digital Signal Processor (DSP) or a single chip Microcomputer (MCU).

In a specific implementation of the present invention, the central control unit is further configured to compare a distance value between the glasses frame and an object in front of the glasses frame, which is sent by the infrared distance measuring sensor, with a preset learning state judgment distance range (a range greater than 30 cm and less than 1 meter), judge that the user is in the learning state when the distance value is within the preset learning state judgment distance range, at this time, send a trigger start signal to the timer, control to start the timer, and enable the timer to start to count the continuous learning time of the user in real time. Therefore, based on the technical scheme, the starting of the timer can be automatically controlled according to the learning state of the user.

In the invention, the children myopia prevention glasses further comprise a touch key module;

the touch key module is arranged at the top or the side of the glasses frame and used for receiving a preset control instruction (such as an opening or closing control instruction aiming at the infrared ranging sensor and the timer) input by a user and then forwarding the preset control instruction to the central control unit;

and the central control unit is also connected with the touch key module and is also used for executing corresponding operation according to a preset control instruction input by a user, for example, correspondingly controlling the infrared distance measuring sensor and the timer to be turned on or turned off.

It should be noted that, for the invention, the sensor and the timing module can utilize the built-in infrared ranging sensor and a timer, when the child learns, the distance between the eyes and the book is monitored, when the distance is less than 30 cm, an alarm is given out, so that the child keeps the correct learning posture; the module can calculate the continuous learning time of the children, if the continuous learning time exceeds 1 hour, a voice prompt is given to tell the children that the eyes need to be closed, the children need to look out a long distance or do proper sports, the fatigue of eyes is relieved, and therefore a good learning habit is formed.

In the present invention, the voice prompt module may be a sound player mature in the prior art, for example, an existing sound player configured by a voice module, a control circuit, a speaker, a power supply and a housing, and the voice prompt module may perform corresponding voice prompt for the child according to the distance value and the continuous learning time calculated by the sensor and the timing module.

In the present invention, in a specific implementation, the spectacle frame is preferably made of a silica gel material. Because the glasses picture frame has adopted soft comfortable silica gel material, can prevent phenomenons such as mirror leg fracture from injuring children, the silica gel spectacle-frame is worn lightly, comfortable moreover, can alleviate glasses and feel to the oppression of the bridge of the nose.

In the present invention, in a specific implementation, the eyeglass lens is preferably a blue light-proof lens. Due to the adoption of the blue-light-proof lens capable of protecting eyes, the blue-light-proof and radiation-proof functions can be realized, the damage of electronic products such as computers, mobile phones and ipads to the eyes is reduced, the delicate eyes of children are protected, and the purpose of preventing myopia can be achieved.

In the present invention, referring to fig. 2, a sensor and timing module 9 and a voice prompt module 10 are installed at the middle nose bridge part of the glasses frame 1.

In particular, the sensor and timing module 9 comprises a timer 4, an infrared distance measuring sensor 5 and a switch key 3;

in particular, the voice prompter module 10 comprises a loudspeaker 6, a control circuit 7 and a battery 8;

the battery 8 is electrically connected with the loudspeaker 6 and the control circuit 7.

It should be noted that the central control unit, which may also be mounted in the central nose bridge portion, may be internal or on the rear side of the central nose bridge portion.

It should be noted that, aiming at the current situation that the myopia rate of children in China is rising and the problem of low age is prominent, the main factors causing myopia are two key points of long-time short-distance eye use and electronic product use. The invention aims to provide children myopia prevention glasses, which can monitor the distance between eyes and books when children learn, and can give out an alarm when the detected distance is less than a preset distance (for example, 30 centimeters), so that the children can develop a correct learning posture; meanwhile, when the continuous learning time of the child exceeds the preset time (for example, 1 hour), a voice prompt is sent to remind the child to have a rest on eyes, and the eyestrain is relieved, so that a good learning habit is formed. Therefore, the invention can ensure that the children keep correct learning postures and form good learning habits, and really achieves the purpose of preventing the myopia of the children in advance.

In order to more clearly understand the technical solution of the present invention, the following description is given with reference to specific examples.
