Description
Technical Field
The utility model belongs to the field of vision correction devices, and particularly relates to glasses with adjustable focal lengths.
Background
At present, most of common glasses used by people are fixed in focal length, and the glasses need to be replaced regularly along with the change of the myopia degree. In recent years, spectacles capable of adjusting focal length have appeared, but the spectacles are complex in structure and heavy in appearance.
The lenses of the commercially available focus adjustment glasses have a double-layered structure, which is provided because objects seen by the wearer are kept from being deformed. However, the double-layer lenses are thick and heavy, and cause a certain pressure on the eyes of the wearer. However, if the lens is a single layer lens, the accuracy is low, which may cause serious deformation of the object viewed by the wearer. For example, Eyejusters designs a pair of glasses with double layers of lenses in a targeted manner, when wearing Eyejusters glasses, a myope can realize the movement of the rear lenses by rotating a knob at the right side of a spectacle frame, which is equivalent to focusing, until a distant scene can be clearly seen. The zoom glasses are low in cost and can be worn without optometry, and the trouble that people need to replace new glasses due to vision deterioration is effectively avoided. However, the above-mentioned spectacles also have the aforementioned problem that the double-layered lenses are thick and exert a certain pressure on the eyes.
In view of the above problems, it is desirable to invent a pair of glasses that is more portable and can adjust the focal length.
