A strap secured to the goggles adjacent the temples secures the goggles to the wearer's head. A rigid frame is secured to the periphery of the flexible frame, the rigid frame having a channel adjacent the upper and lower edges of the flexible frame which is adjacent the temple area. Lenses including a peripheral flange receivable within the channel of the rigid frame are slidable within the channel to locate each lens with respect to the rigid frame. A rigid handle or grip is secured to the temple portion of the lens to close the open end of the channel and to lock the lens to the flexible frame.
