A protective eyeglass assembly includes a frame having left and right lens frame portions, lens receiving apertures in the frame portions, a central bridge portion connecting the frame portions, and left and right temple bars. The eyeglass assembly further includes an integrally formed lens piece which is adapted to be detachably secured to the frame so that a user can interchange the frame and/or replace the lens piece. The lens piece includes left and right lens panels, a central bridge portion connecting the lens panels, left and right side shields, and left and right upper shields. The lens piece is received in assembled relation with the frame with the left and right lens panels aligned in registry with the left and right lens frame portions. The lens panels and bridge portion of the lens piece have an outer peripheral margin which is substantially similar to the left and right frame portions and bridge portion of the frame such that the lens piece is substantially hidden when viewing the eyeglass assembly from a frontal viewing position. The left and right lens panels further include stepped lens formations which are received in interfitting engagement into the lens receiving apertures of the frame when the lens piece is assembled with the frame. The temple bars are angularly adjustable with respect to the frame portion, and are further 23 telescopically adjustable in length.
