Background

The presbyopia, commonly known as presbyopia, is a physiological phenomenon that after the age of 40, people gradually harden the crystalline lens, the eye muscles are gradually paralyzed, the eye accommodation force is reduced, specific close-distance targets in front of eyes cannot be seen clearly, and reading or close-distance observation cannot be carried out, and is a visual problem which can occur in most of middle-aged and old people. The primary presbyopia has two main manifestations: first, work or reading difficulties at close distances; for example, when reading, a book needs to be taken away, or the book needs to be seen clearly in a place with strong light; secondly, asthenopia, such as eye swelling and headache, occurs when the reading demand gradually approaches the regulation limit. After presbyopia, the most common and effective methods require the use of presbyopia corrective lenses to aid viewing, i.e., the correction of presbyopic glasses, for reading or other viewing tasks.

Chinese outward appearance patent CN307544328S discloses a folding glasses component, which comprises glasses frames and glasses legs, wherein a nose bridge is arranged between the glasses frames, a rotating shaft is arranged at the center of the nose bridge, and the glasses frames at two sides are hinged to the front and the back of the rotating shaft in a front-and-back mode so as to rotate along the circumferential direction of the rotating shaft; the mirror leg articulates in picture frame one side, and the mirror leg includes through articulated rotating part and the folding portion of connecting, the rotating part is used for making the mirror leg rotate towards picture frame one side, the folding portion can be adducted in the rotating part.

Above-mentioned folding glasses subassembly is when folding, in order to avoid taking place to interfere between folded part and the picture frame, must be earlier in the folded part need be adducted in the rotating part, then just can be to carrying out the rotation folding between rotating part and the picture frame, and folding process must go on according to this step sequence, and the operation is troublesome relatively. And the overall thickness of the folded glasses is increased due to the overlapping relationship between the folding part and the rotation part of the temples.
