Advantageous effects

Compared with the prior art, the utility model discloses a quick upset glasses's beneficial effect is:

1. is convenient to use. The hanging glasses for treating myopia in the market are split combined glasses which adopt a main mirror and a magnetic hanging mirror, are inconvenient to assemble and disassemble repeatedly, and are easy to lose. The fast turnover glasses which are turned up and down are turned over by hands when people look near and look far, and the fast turnover glasses are convenient but are sometimes troublesome and do not turn over. The automatic control system adopting the controller automatically controls the miniature speed reduction motor to drive the lens to automatically turn over, the lens automatically turns up when looking near, and the lens automatically turns down when looking far, so that the automatic lens turning-over device is very convenient to use, easy and worry-saving.

2. The visual field is wider. Bifocal lenses and progressive multifocal lenses are divided into a plurality of areas on one lens, the distance-seeing area and the near-seeing area are both small, the visual field is not wide, a boundary line is arranged in the middle, the visual line is blocked, and the bifocal lenses and the progressive multifocal lenses are very uncomfortable to see. When looking near, the eyes need to look obliquely downwards and form a certain angle with the lens in the near light area, which is uncomfortable. Therefore, the wearer tends to see near objects with the upper light zone directly viewed, and thus the anti-myopia effect of the progressive addition lens is not obvious. The progressive multi-focus lens cannot be used for watching a computer by using a lower light area, and does not have the function of myopia prevention when watching the computer and a display screen. The utility model discloses a lens uses whole lens to watch, can all watch with whole lens when reading and writing and looking level up telescope, and the field of vision is as wide as single ordinary lens.

3. Avoid forgetting. The hanging mirror needs to be repeatedly hung and taken off, which is not only troublesome, but also can not be found when people want to wear the hanging mirror once the hanging mirror is forgotten at home or in a certain corner after being taken off. The manually-turned glasses sometimes forget to turn over and always use one lens to watch, and the corresponding preventive effect is lost. The utility model discloses an automatic upset glasses's upset picture frame is a body structure with fixed picture frame, and upset glasses are taken on one's side all the time, can not forget, and the lens can overturn automatically moreover, and the automatic identification scenery is far and near, and the automatic switch-over lens looks far and near as required at any time.

4. The appearance is beautiful. The lens is complete, the appearance of the lens is not much different from that of common glasses, and the lens cannot generate unnatural feeling even being turned upwards and does not influence the appearance. The outstanding surrounding edge of a circle is arranged around the mirror frame, so that a gap between the turnover mirror frame and the fixed mirror frame can be shielded, the mirror frame looks like a complete mirror frame all the time, and the aesthetic feeling of the appearance is enhanced.

5. And (4) safety. The utility model discloses do not do laser surgery and need not take the contact lens of cornea not having the operation, contactless eyeball just can let eyesight reply gradually and prevent that myopia from further increasing, can avoid doing the injury and the later stage complication that laser surgery caused the cornea of eye, can avoid the wearing and tearing and the injury of moulding mirror of cornea to the cornea of eye. The utility model is not in contact with eyes, adopts pure physical therapy, and has no any damage and side effect.

6. The application range is wide. The utility model is not only suitable for preventing and curing myopia, but also suitable for presbyopic glasses and glasses with special functions. The utility model discloses also be fit for the occasion of other automatic switch-over inside and outside lenses, also can regard as after special design to look function training glasses like control system, automatic switch-over sees far away and sees near. The utility model discloses a controller can also combine earphone and MP3, take a picture, make a call, functions such as osteoacusis, become multi-functional intelligent glasses.
