[0002] Defocus glasses are a type of corrective glasses for vision problems such as myopia and hyperopia. They improve vision by adjusting the focusing point of light.

[0003] At present, with the increase of electronic devices and the increase of academic pressure, today's children have become myopic due to continuous close viewing, causing children to wear glasses from a very young age. Therefore, at the request of parents, the increase of degree of myopia is suppressed by letting children wear defocus glasses to avoid the increase of myopia.

[0004] However, during the use of traditional defocus glasses, as children grow every day, their pupil distance also increases. Therefore, the existing defocus glasses cannot be changed according to the pupil distance, which reduces the adaptability of the defocus glasses.

DETAILED DESCRIPTION

[0028] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0029] Embodiment 1

[0030] like Figure 1-Figure 3 As shown, a defocused glasses for different pupil distances of the present embodiment comprises a frame 1, two defocused lenses 2 embedded in the frame 1 and two sets of distance adjusting devices 4, and the frame 1 and the distance adjusting devices 4 are both made of titanium alloy, which has the advantages of light weight, high strength, wear resistance and corrosion resistance.

[0031] Specifically, the frame 1 includes a cross bar 11 and two frame bodies 12, and the two defocused lenses 2 are respectively embedded in the two frame bodies 12. A nose pad 3 is installed at the bottom of the cross bar 11 and in the middle of the cross bar 11. The bottom of the cross bar 11 is connected to the tops of the two frames 1 through two sets of distance adjusting devices 4, and the two frames 1 are mirror-symmetrical about the midline of the nose pad 3; the two sets of distance adjusting devices 4 are installed inside the cross bar 11 in a mirror-symmetrical manner about the midline of the nose pad 3, and the two sets of distance adjusting devices 4 can respectively drive the two frames 1 to move toward or away from the nose pad 3 to adjust the distance between the two defocused lenses 2. Two distance adjusting devices 4 are installed inside the cross bar 11, and the bottoms of the two distance adjusting devices 4 are connected to the tops of the two frames 12, which can drive the two frames 12 to move laterally in the direction of approaching or away from the nose pad 3, so as to adjust the distance between the two defocused lenses 2. Since children of the same age group have different head circumferences, different eye distances, and thus different pupil distances, and for children of different age groups, the head circumferences, eye distances and pupil distances are even more different, therefore, the utility model can drive the defocused lenses 2 to move laterally through the distance adjusting devices 4, so as to change the distance between the defocused lenses 2, so as to be more suitable for the pupil distances of children of different age groups. At the same time, it can also avoid the need for children to wear new defocused glasses when they grow to a certain age, so that the defocused glasses are more adaptable, the cost of adapting the defocused glasses is reduced, the structure is simple, and the operation is convenient and quick.

[0032] Furthermore, the distance adjustment device 4 includes a driving member 41, a transmission shaft 42 and a moving assembly 43; the interior of the crossbar 11 is provided with an installation space 13 for installing the driving member 41 and a moving space 14 for installing the moving assembly 43, and the opening of the moving space 14 faces the frame 12, the driving member 41 is connected to the moving assembly 43 through the transmission shaft 42, and the bottom of the moving assembly 43 is connected to the frame 12; the driving member 41 drives the transmission shaft 42 to drive the moving assembly 43 to move in the moving space 14, and then drives the frame 12 to move laterally in a direction close to or away from the nose pad 3. By providing the driving member 41, the transmission shaft 42 and the moving assembly 43, the movement of the frame 12 can be automated, that is, by driving the driving member 41, the distance between the two frames 12 can be changed, and then the pupil distance of the defocused glasses can be changed, so that they are suitable for children of different ages to wear. Preferably, the moving component 43 includes a threaded rod 431 and a slider 432; one end of the threaded rod 431 is rotatably connected to the inner wall of the moving space 14, and the other end is fixedly connected to the transmission shaft 42; the slider 432 is sleeved on the threaded rod 431 and the bottom of the slider 432 is connected to the top of the frame 12; the top wall and two side walls of the slider 432 are both in contact with the top wall and two side walls of the moving space 14. By arranging the threaded rod 431 in the moving space 14, and one end of the threaded rod 431 is fixedly connected to the transmission shaft 42, the driving member 41 can drive the threaded rod 431 to rotate when the driving shaft 42 rotates, and the slider 432 sleeved on the threaded rod 431 is threadedly matched with the threaded rod 431. When the threaded rod 431 rotates, the slider 432 can move along the axis of the threaded rod 431, thereby driving the frame 12 to move, thereby achieving the effect of changing the pupil distance.

[0033] Furthermore, the moving assembly 43 also includes two limit switches 433; the two limit switches 433 are installed on the side walls at both ends of the moving space 14, and are used to limit the movement of the slider 432. By setting the limit switch 433, the movement of the slider 432 can be limited. When the slider 432 moves under the rotation of the threaded rod 431, once the slider 432 touches the limit switch 433, the driving member 41 immediately stops working, that is, the movement of the frame 12 reaches the limit, and the slider 432 is prevented from moving to the end point of the moving space 14 in the moving space 14. The driving member 41 continues to drive, and the transmission shaft 42 cannot continue to transmit, thereby causing damage to the motor. Preferably, the driving member 41 is a micro forward and reverse motor, which has the characteristics of easy installation and easy carrying. It can also reduce the occupied space during installation, avoid space waste, and ensure the aesthetics of the defocused glasses.

[0034] Furthermore, the defocus glasses for different pupil distances of this embodiment further include two illuminating lamps 5, which are installed on the front walls at both ends of the crossbar 11 to supplement the light source. At night or on cloudy and rainy days, children will inevitably encounter insufficient light sources during their studies, and the provision of the illuminating lamps 5 effectively improves the eye use needs of children and avoids the increase of myopia of children due to dim background.

[0035] Furthermore, a defocused glasses for different pupil distances in this embodiment also includes two temples 8; the two temples 8 are hinged at the two ends of the cross bar 11, and bone conduction headphones 6 are installed near the tail ends of the two temples 8. By providing the bone conduction headphones 6, children can listen to online classes and study in a noisy public environment. Moreover, the bone conduction headphones 6 can make it possible to hear sounds without entering the ears of the children, thereby preventing the children from wearing in-ear headphones for a long time to cause damage to the eardrum.

[0036] Furthermore, a reminder device 7 is installed inside one of the temples 8, and the reminder device 7 is used to remind the user to correct the head tilt. It should be noted that the reminder device 7 can be installed in one temple 8, or the reminder device 7 can be installed in both temples 8.

[0037] Specifically, the reminder device 7 includes two level sensors 71, two speakers 72 and a sensor switch 73; the two level sensors 71 are installed inside the middle of the two temples 8 and the side walls of one side of the two level sensors 71 are flush with the side walls of the opposite sides of the two temples 8, the two speakers 72 are installed inside the temples 8 close to the crossbar 11, the level sensors 71 are electrically connected to the speakers 72, and the sensor switch 73 is installed on the top wall of the temple 8 above the level sensors 71, and is used to turn on or off the level sensors 71. The basic principle of the level sensor 71 is to use the torque generated by gravity to determine whether the object is in a horizontal position. Under the action of gravity, the object will be subjected to a downward gravity, and the center of gravity will move downward, thereby generating an upward reaction torque. When the object is in a horizontal position, the reaction torque is equal to the torque generated by the downward movement of the center of gravity, and the object is in a balanced state. When the child tilts his head, the horizontal sensor 71 detects that the horizontal position has changed, and transmits the electrical signal of the horizontal position change to the speaker 72. When the speaker 72 receives the electrical signal from the horizontal sensor 71, it makes a sound, thereby realizing the function of reminding the child of the tilted head, improving the child's sitting posture, thereby avoiding the dislocation of the cervical vertebra, spine, lumbar vertebrae, etc. caused by the child's frequent tilted head, and avoiding the strabismus caused by the child's tilted head, so that the child's growth is healthier. In order to enable the child to swing his head back and forth so as to do homework, read books, etc. at a close distance, the horizontal sensor 71 can be set to a single-axis inclination sensor. The single-axis inclination sensor is only sensitive to the inclination of the selected axis and does not respond to the inclination in other directions. In this way, it can specifically detect the inclination change in the left and right directions without involving the front and back directions, effectively improving the misalignment of the child's cervical vertebrae, spine, lumbar vertebrae, etc., and avoiding strabismus caused by the child's tilted head. A sensor switch 73 is set, and when the child has a need to adjust the sitting posture, that is, when studying or doing homework, the sensor switch 73 can be turned on to correct the child's sitting posture; when the child is engaged in outdoor leisure activities or doing handicrafts and other activities, the sensor switch 73 can be used to turn off the horizontal sensor 71 to allow the child to move normally.

[0038] Furthermore, a battery compartment is provided inside the end of the temple 8, and a power source is installed in the battery compartment to supply power to the driving member 41, the lighting lamp 5, the bone conduction earphone 6, the level sensor 71 and the speaker 72. The power source can be a button battery or a rechargeable lithium battery, etc., which can reduce the occupied space and also realize the function of power supply, so that the driving member 41, the lighting lamp 5, the bone conduction earphone 6, the level sensor 71 and the speaker 72 have a power source.
