Abstract

The invention concerns a series of underwater vision articles comprising two optical elements (1, 3), two sealing elements placed in contact with the face via their right and left contact areas (2, 4), having the following characteristics: the optical elements are placed flatly on a plane on the side opposite the contact areas: P1, P2 represent respective points that are the lowest and to the furthest left from the inner edge (5) or outer edge (6) of the left contact area (4); P3, P4 represent respective points that are the lowest and the furthest right from the inner edge (7) or outer edge (8) of the right contact area (2). Independent of the size, the ratio between PP2,4 and PP1,3 is constant, and/or the ratio between, on the one hand, PP2,4 and a constant and, on the other, PP1,2 is constant or PPi,j is the distance between Pi and Pj for any i and j.

Dependent claims

A series of underwater vision articles, comprising several articles of different sizes, said articles including a right optical element itself including a right sealing element intended to come into contact via its right contact area with the face of a person, and a left optical element itself including a left sealing element intended to come into contact via its left contact area with the face of a person, wherein when said right and left article elements are placed down flat on a same supporting plane on their side opposite to the side of said right and left contact areas of said right and left sealing elements the following points are present:

P1 being the lowest point of the inner or outer edge of said left contact area,
P2 being the leftmost point of the inner or outer edge of said left contact area,
P3 being the lowest point of the inner or outer edge of said right contact area,
P4 being the rightmost point of the inner or outer edge of the right contact area,
wherein regardless the size of said articles in the series, at least one of the ratio between PP2,4 and PP1,3 is constant to within 5%, and
the ratio between PP2,4 plus a constant predefined to within 5%, and PP1,2 is constant to within 5%, wherein PPi,j is the distance between Pi and Pj, for any i and j.
