• a first lens, including a first eye side and a first water side;
• a second lens, including a second eye side and a second water side;
• a first retaining wall protruding from the first eye side of the first lens, the first retaining wall defining a first visible area and a first connection area of the first lens, the first retaining wall having a first continuous closed curve contour enclosing the entire first visible area of the first lens, the first continuous closed curve contour being less complicated than a peripheral configuration of the first lens;
• a second retaining wall protruding from the second eye side of the second lens, the second retaining wall defining a second visible area and a second connection area of the second lens, the second retaining wall having a second continuous closed curve contour enclosing the entire second visible area of the second lens, the second continuous closed curve contour being less complicated than a peripheral configuration of the second lens;
• a first skirt portion, being disposed on the first retaining wall along the first continuous closed curve contour and having a first wrapping part completely wrapping the first connection area of the first lens;
• a second skirt portion, being disposed on the second retaining wall along the second continuous closed curve contour and having a second wrapping part completely wrapping the second connection area of the second lens;
• a first frame portion, the first connection area of the first lens being affixed in the first frame portion;
• and
• a second frame portion, the second connection area of the second lens being affixed in the second frame portion;
• wherein the first connection area is coplanar with the first visible area, and the second connection area is coplanar with the second visible area;
• wherein the first connection area is an area completely surrounding a portion of the first lens, and the second connection area is an area completely surrounding a portion of the second lens;
• wherein the first retaining wall protrudes from and is provided on the first eye side of the first lens by glue or ultrasonic welding, and the second retaining wall protrudes from and is provided on the second eye side of the second lens by glue or ultrasonic welding.
