Abstract: Swimming or diving goggles includes a lens unit including two viewing sections. A front face of each viewing section is a portion of a peripheral face of a cone. The cone has an apex and a bottom face, and the peripheral face extends between the apex and the bottom face. A spacing from a top face of each viewing section to a vertical axis passing through a center of the bottom face in the thickness direction is smaller than a spacing from a bottom face of the viewing section to the vertical axis in the thickness direction. A normal plane perpendicular to each of the two viewing sections is at an acute angle with the vertical axis. Each viewing section is a curved face in a circumferential direction about the vertical axis. A frame mechanism is coupled to the lens unit and in intimate contact with eye sockets of a wearer.

Abstract: A pair of swimming goggles includes two lens assemblies and a bridge mounted between the lens assemblies. An inner side of each lens assembly includes a bridge coupling portion having a longitudinal axis at an acute angle with a central vertical axis of the bridge. The bridge includes two legs and an arcuate section interconnected between upper ends of the legs. The bridge defines a space having increasing widths toward lower ends of the legs coupled with the bridge coupling portions. A spacing between a rear side of the lower end of each leg and a vertical axis extending through a rear side of one of the lens assemblies is smaller than a spacing between a rear side of the arcuate section and the vertical axis. The arcuate section has a rear arcuate face. A spacing from the rear arcuate face to the vertical axis decreases downward.

Abstract: A pair of swimming/diving goggles includes a goggle body, a buckle, and a head strap. A wall delimiting a through-hole in the goggle body includes a pressing face. A pin is mounted to the buckle. An end of the head strap extends through the through-hole, a gap between the pin and an inner face of the buckle, and then extending through the through-hole again. When an outer portion of the head strap is pulled and then released, a clamping force provided by an inner portion of the head strap moves the pin to a position in which the head strap is tightly clamped between the pin and the pressing face. When the buckle is moved toward an inner end of the through-hole, a gap between the pin and the pressing face becomes larger to allow loosening of the head strap.
