PROBLEM TO BE SOLVED: To provide a spectacle frame which allows the easy and rapid interchange of lenses of different kinds with the one frame according to applications. SOLUTION: The frame consists of a full circumference structure and has a shape to allow the separation of the joint surfaces of lens mounting parts. The frame 1 is provided with spherical rods 2 on its one side and is formed with recessed parts 3 for inserting and holding the spherical rods 2 on the other side. The frame 1 is joined by compressing fingers from two upper and lower points thereof. As an example, the joint surfaces of the frame 1 are parted and the taking out of the lenses is made possible by pressing pad parts 4 connected to the frame 1 with the thumb and pressing these parts in a direction reverse from the joining direction.
