At present, the myopia glasses are worn more and more due to myopia of eyes, and great inconvenience is brought to life, study, work and human health, wherein overlong eye use time, too close eye use distance, and too strong or too weak illumination light are main causes for inducing myopia diseases. With the technological progress and the development of society, modern people have shortsightedness because of excessive contact with electronic products, such as mobile phones, tablet computers and the like, and some unhealthy eye-using habits are formed, so that more and more people are in shortsightedness. In addition, modern people also have myopia due to improper eye use reasons such as too close eye use distance or sitting posture. The measures for treating myopia comprise wearing glasses and laser treatment, the laser treatment has certain risk, the wearing of the glasses is the most common method for correcting myopia for people, but the wearing of the glasses can only enable the myopia eyes to see clearly, the myopia cannot be prevented, the original vision of the eyes cannot be recovered, and the myopia degree of the eyes can be aggravated when the glasses are worn for a long time. Myopia is difficult to cure once it has developed, so care should be taken to prevent myopia during use.

According to the method and the device, when the situation that the distance between the objects to be read is too short or the sitting posture of the user is not correct is detected, the motor 70 is controlled to work firstly, vibration is sent out, and after the preset time, for example, 5S, is found out, if the situation that the distance or the sitting posture of the user is not adjusted is detected again. That is, the distance between the objects to be read is still too short, or the sitting posture of the user is still not good, the power supply 51 of the liquid crystal lens 30 can be turned off after the vibration warning. Wherein, the vibration frequency of the motor 70 in one detection period is adjustable, for example, the vibration is stopped after 3-5 times of vibration. And, can carry out the vibration of motor 70 of 1 ~ 3 detection cycles and remind before turning off power supply 51, if still reminding invalid after many cycles, turn off the power again. Like this, wear glasses, when the user is less than 35mm with being read apart from books distance between the thing, glasses can vibrate slightly, remind the user to need adjust viewing distance apart from being too close, if not adjusting suitable viewing distance yet, glasses lens can become dark automatically, force the user to adjust suitable viewing distance, when the posture is not upright, glasses can vibrate slightly, remind the user to keep the correct position of sitting, if not adjusting the position of sitting yet, the lens also can become dark automatically, force the user to keep normal position of sitting.

The main controller 52 can also count the single time of the glasses, or the total time of use in a use period, such as a week, so as to remind the user when the glasses are worn by the user for too long time. Or when the service life of one service cycle is too long, a corresponding reminder can be made. The reminding can be realized by turning on or off the main controller 52 for controlling the power supply of the liquid crystal lens 30, for example, flashing once or vibrating once, for example, vibrating 10 times continuously. Thereby preventing the user from using too much eyes or using too long eyes to cause myopia.
