Abstract
An engaging and securing structure of flip-up eyeglasses includes a first lens and a second lens. The first lens is provided with an engaging portion. The engaging portion is provided therein with a first engaging groove and a second engaging groove. The second lens is provided with an engaging block. The engaging block has a non-circular cross section and peripherally forms a plurality of corners that correspond to the first engaging groove or the second engaging groove and are defined as engaging corners. Any of the engaging corners can be selected to be engaged in the first engaging groove or the second engaging groove. The first lens and the second lens are made of plastic and are held together without using metal screws or elastic elements, thereby preventing occupational safety accidents attributable to electrical conduction through such metal screws or elastic elements.
