ABSTRACT:
Glasses for use in sports activities and the like have a frame, at least one lens formed to the frame, and a strap formed to the frame which is configured to inhibit the glasses from falling off of a wearer. A leash is formed to the strap and a collar formed to the leash. The strap, leash, collar or other component of the present invention may optionally be sufficiently buoyant so as to float the glasses in water. A breakaway clip releases the collar from a wearer if the glasses, strap, leash, or collar get caught.
