Abstract

The invention discloses a device for preventing myopia including a desk clamp and an alarm device. The desk clamp is a U-shaped clamp. A clamp opening of the desk clamp can clamp a desk edge. The alarm device is arranged on an upper surface of the desk clamp. A power supply, an inductor, a processor, and an alarmer are arranged in the alarm device. The inductor induces whether an object blocks the upward side of a through hole through the through hole arranged in the upper end of the alarm device. If the object blocks the upward side of the through hole, a blocking signal is transmitted to the processer, and the processer analyzes the blocking signal transmitted from the inductor. If a blocking time reaches a critical point, an alarming signal is transmitted to the alarmer and the alarm is sounded. The device for preventing myopia has a simple and reasonable structure, can prompt a user to correct a sitting posture by triggering the alarm sound, thereby effectively preventing the myopia caused by the wrong sitting posture.

Description

technical field [0001] The invention relates to an eye protection device, in particular to an anti-myopia device. Background technique [0002] Myopia refers to a pathological state in which the eyes see clearly near but not far. When people with myopia look at a distance, the parallel light rays parallel to the visual axis are refracted by the eye's refractive system and converge in front of the retina, which cannot form a clear image on the retina, so they cannot see clearly, which belongs to a kind of refractive error ; and when looking at nearby objects, the image will move back to the retina so that it can be seen clearly. People with high myopia are at high risk of some eye diseases, such as retinal detachment and glaucoma, because of their long eye axis. Myopia is quite prevalent all over the world. The number of people with myopia in China has reached 1 / 3 of the country's population. In order to effectively prevent the occurrence of myopia in young people, many m...
