  • Snap-on sunglasses
    Patent number: 8702231
    Abstract: Sunglasses replaceably attached to conventional spectacles. The sunglasses include a frame, a pair of tinted lenses, and two pair of attachments. The frame replaceably attaches to a frame of the conventional spectacles. The pair of tinted lenses are attached in the frame. The two pair of attachments extend from the frame and replaceably snap the sunglasses onto the frame of the conventional spectacles to eliminate inadvertent movement of the sunglasses relative to the conventional spectacles during use without impinging upon hinges of the frame of the conventional spectacles so as to allow the sunglasses to fold with the conventional spectacles.
