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.
