Eyewear includes a lens unit and a frame mechanism coupled to the lens unit. The lens unit includes two viewing sections each having a front face that is a portion of a peripheral face extending between an apex and a bottom face of a cone. The apex is below the bottom face of the cone. A vertical axis passes through a center of the bottom face of the cone. A spacing from a top edge of each viewing section to the vertical axis in a thickness direction is smaller than a spacing from a bottom edge of the viewing section to the vertical axis in the thickness direction A normal plane perpendicular to each viewing section is at an acute angle with the vertical axis. Each viewing section is a curved face in a circumferential direction about the vertical axis.
