ABSTRACT:
Improved eyewear having a single lens (22) supported by a frame (20) which has temples (26) attached to either side by hinges (24). A wrap-around configuration of the frame and lens essentially hides a single circumferential frame to face water impermeable seal assembly (32) comprising a foam rubber layer (34) overlying a deflatable bladder (36). The inner side of the seal is contoured to fit against the human face and the outer side of the seal is contoured to fit within the frame and lens. Extending from the temples are adjustable retaining means (41) comprising two elongated tubular members (40) with open ends formed of a flexible resilient material, being adjusted by a releasable friction catch (44) to prevent the catch from becoming separated from the tubular members. Tubing (38) connects the bladder (36) and interior portions of the glasses to air removal means which can take the form of a mouthpiece (52) or pump (78) placed at the end of the retaining means or attached to the temple ends ( 30). Air removal means allow the wearer to deflate or inflate the bladder, and to remove air from the interior portion of the glasses, creating a slight vacuum and a better watertight seal with the face.
