Description

FIELD OF TECHNOLOGY

The following relates to the technical field of glasses, especially a composite glasses structure of rimless glasses, semi-rimless glasses and full-rim glasses.

BACKGROUND

In the existing technology, the glasses are divided into rimless glasses, semi-rimless glasses and full-rim glasses. In general case, different sports need to wear different glasses, e.g. when playing golf, rimless glasses are usually used to avoid sight line blocking and ensure light sport; when riding, semi-rimless (upper rim) glasses are usually used to ensure that sweat on the lenses is able to flow down.

The Chinese patent document CN203732816U disclosed a lens quick-release snap-fitting glasses structure in Jul. 23, 2014. It realizes the detachable connection of the upper rims and the lens assembly in the technical scheme of the patent, but not includes the rimless, lower rim and full-rim functions.

In the existing technology, the rimless, half-rimless or full-rim functions cannot be gathered in one pair of glasses at the same time, so that when carrying out different sports, different glasses are used, which increases the cost and decreases the convenience to carry and use.

In the existing technology, glasses typically consist of earpieces and lens assembly. The earpieces are pivotally coupled to the lens assemblies, and be capable of being folded and opened.

In the existing technology, the glasses body and lens assembly are typically assembled and non-removable, and the lenses in the lens assembly are also non-removable so as not to facilitate the cleaning and replacement of the lenses.

The Chinese patent document CN204203562U disclosed a kind of connecting glasses structure of rims and lenses on Mar. 11, 2015. The connecting glasses structure provided in the technical scheme of the patent uses the rotating block to achieve the removable lenses, but there still are some deficiencies, namely, it cannot adjust the earpieces outreach range.

Since the size of the wearer's head is different, and the distance between the two earpieces in the existing technology can generally not be adjusted, so that the glasses do not apply to different wearers and the comfort of the wearers also be affected.
