Abstract
The eyeglasses frame is provided with spaced, oppositely extending, coplanar recesses. The lens sections of the sunglasses are provided with first and second oppositely directed collinear protrusions. An enclosed spring bridge mechanism moveably connects the lens sections. The spring bridge mechanism permits the lens sections to be moved toward each other, compressing the spring, to insert the protrusions into the recesses. The spring urges the lens sections away from each other, seating the protrusions into the recesses, to mount the sunglasses on the eyeglasses frame.
