Claim:
Swimming or diving goggles comprising: a lens unit of rigid material, including two separate lenses or a single monolithic lens with a thickness, with the lens unit including two viewing sections: each having a front and a rear face spaced from along the direction of thickness, with the front face being a portion of a peripheral face of a cone, with the cone having an apex and a bottom face, with the peripheral face extending between the apex and the bottom face, with each of the two viewing sections having a top face and a bottom face spaced in a vertical direction perpendicular to the thickness direction, with a spacing 1 a less than a spacing 1 b, wherein the spacing 1 a is defined as the distance along the direction of thickness from the top face of each of the two viewing sections to a vertical axis passing through a center of the bottom face of the cone, and the spacing 1 b is defined as the distance along the direction of thickness from the bottom face of each of the viewing sections to the vertical axis passing through the center of the bottom face of the cone, with a normal plane perpendicular to each of the two viewing sections being at an acute angle with the vertical axis, with each of the two viewing sections being a curved face in a circumferential direction, axially around the vertical axis; and a frame mechanism coupled to the lens unit and in intimate contact with eye sockets of a wearer wearing the swimming or diving goggles.
