Abstract
Lensless safety sunglasses formed of fabric material die cut or otherwise contoured to define a soft, breathable frame having a pair of eye openings and temple pieces extending from opposite ends of the frame adapted to go around the head of the wearer to hold the frame, in the manner of a face mask, against the eyes of the wearer. Laminated to the fabric frame and overlying the eye openings is a fabric scrim which acts as a light-permeable screen to reduce the intensity of light passing through these openings, thereby preventing glare without however interfering with vision.
