Description

Technical Field

[0001] The utility model relates to the field of glasses, in particular to a detachable glasses leg structure and glasses. Background Art

[0002] Glasses are a type of eyewear used to correct vision or protect the eyes. They consist of lenses and frames. There are many types of glasses, including those for myopia, hyperopia, astigmatism, reading glasses, sunglasses, and protective glasses. Each type of glasses has its own specific function and purpose.

[0003] Presbyopia is a physiological phenomenon that everyone will experience. It is the gradual aging process of the eye's refractive system. It has an impact on the vision health of people over the age of young and middle-aged in terms of near vision clarity, visual fatigue, etc. Progressive multifocal lenses are seamlessly configured with different vertex powers on a single lens. Wearing such lenses can achieve the effect of free and smooth movement of vision from far to near vision. When wearing such lenses, the forward tilt angle of the glasses needs to be adaptively adjusted according to the wearer's facial features. When adjusting the forward tilt angle of existing glasses, pliers need to be used for rigid adjustment, which causes greater damage to the glasses. In addition, the existing glasses legs and frames are mostly integrated or connected by bolts, which are inconvenient to disassemble and assemble.
