[0057] In a further related embodiment, the face lens 1012 can be configured with a promotion region, positioned in a location which does not interfere with the vision of the user, which can be outside the central panoramic vision region 1040, such that a promotional communication 1020, such as a logo 1020, can be positioned in the promotion region, such that the promotional communication 1020 for example can be either as a surface print or a sticker. The promotional communication 1020 can be a text, a graphic image, or a combination of these. Thereby, the promotion region can provide space for a promotional communication 1020, which for example can be a company logo, team name, motivational slogan or message, or some other text or graphical communication. In FIG. 10, the logo 1020, is shown on a top right side of the face lens 1012. Alternatively, a promotional communication 1020 communication be configured on either top right or top left sides, on both top right and top left sides, or in some other location that doesn't interfere with the users vision, such as for example on the nose portion 1060.

[0058] In a another yet further related embodiment, the face lens 1012 can be configured with a nose portion 1060, which is configured to match and overlap with a portion of the nose of a user, such that the nose portion reaches for example at least along 30% (approximately as shown) of the length of a ridge of the nose, or alternatively approximately or at least 40%, 50%, 60%, 70%, 75%, 80%, or 90% of the length of a ridge, or some other coverage percentage, when the hydrodynamic swimming mask 1000 is positioned on the face 182 of a user 180.

[0059] In an another related yet further related embodiment, as shown in FIG. 12, the nose portion 1260 can be configured to completely cover the nose of the user, when the hydrodynamic swimming mask 1000 is positioned on the face 182 of a user 180.
