Lensless safety sunglasses formed of flexible synthetic plastic material die cut or otherwise contoured to define a soft frame having a pair of eye pieces and temple straps 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. The eye openings are created by tiny apertures forming a 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.
