| 1. A transparent and polarizing vision element divided into several zones, at least two of said zones being associated with
a light polarizing filter, the light traversing the element being affected differently for two of said zones according to
a direction of polarization of said light,
the element a spectacle lens and comprising:
a first zone associated with a polarizing filter oriented vertically with respect to a use position of the element, said first
zone being located in a lateral part of the element with respect to the use position;
a second zone associated with a polarizing filter oriented horizontally, the element being characterized in that the second
zone is located in the upper part of the element with respect to the use position; and
a third zone that is not-polarizing and is located in the lower part of the element with respect to the use position, wherein
the element comprises two first zones, each associated with a polarization filter oriented vertically relative to the position
of use of the element and each located adjacent to a lateral edge of the element, and
the second and third zones are located between said two first zones, said third zone being located below said second zone
in the use position of the element, and
said two first zones are separated by a distance lying between 10 and 60 mm in a central portion of said element.
