The frame has an inverted U-shaped portion formed in its inward surface with an open-ended lens receiving slot for engaging with the upper peripheral portion of the lens. Each end of the inverted U-shaped portion has a counterbore formed therethrough. The cord extends through two counterbores in the inverted U-shaped portion and is integrally formed with two enlarged end portions which are confined within the large-diameter outer end portions of the counterbores respectively. One of the interengaging surfaces between the lens and the cord has a slot so that they can be engaged with each other, thereby retaining the lens on the frame with the cord.
