Abstract: An eyeglass assembly includes a lens holding “base-frame” with two temples pivotally attached and extending rearward; this “base-frame” is grooved to hold prescription, reading or sunglass lenses. This “base-frame” marries with various lens-holding front-frames enhancement components. The additional front-frame components have the option of holding prescription, reading or sunglass lenses; or can be used with generic colorized lenses, strictly as a “fashion” statement. The base-frame and front-frame enhancement components utilize magnetized ultra-thin special “rare earth” magnetic materials.

Magnets within the recesses and the temple ends having polar orientations that establish magnetic attraction with each other join the temples to the front through the temple holders. The temple holders reinforce the coupling of the temples with the front during ordinary wear to prevent an undesirable separation of a temple from its front. Selective separation of the temples from the front, however, enables the wearer to change temple styles, as appropriate.
