a temple including a lens assembly element, a latching member, and a temple main body;
wherein the lens assembly element is a one-piece formed structure and includes a first surface and a second surface formed opposite to the first surface, wherein a groove is formed by being recessed on the first surface of the lens assembly element and an embedded opening is formed and disposed at a front side of the lens assembly element, wherein two opposing ends of the embedded opening are in communication with the groove;
wherein the latching member is a one-piece formed structure and is disposed in the groove of the lens assembly element, wherein an elastic piece and a pressing piece extend from two opposing sides of the latching member at a front section thereof and are fixedly attached thereto, wherein the elastic piece is disposed substantially adjacent to a bottom section of the groove and is formed as a flat surface, wherein the pressing piece is disposed at an opened notch section of the groove, wherein a clamping interval is formed between the elastic piece and the pressing piece whereby a section of the clamping interval is corresponding in position with the embedded opening of the lens assembly element, and wherein a block extends from a side of the elastic piece towards the pressing piece to be located in the clamping interval;
wherein the temple assembly part of the spectacle lens is selectively and correspondingly engaged with the embedded opening of the lens assembly element for extending into the clamping interval of the latching member, wherein the buckle hole of the temple assembly part of the spectacle lens is snapped and resiliently coupled with the block extending from the elastic piece of the latching member, wherein the temple assembly part is also laterally clamped within the clamping interval by opposing sidewalls of the elastic piece and the pressing piece, and wherein a rear section of the latching member and a front portion of the temple main body are pivotally connected with the lens assembly element.
