Problems solved by technology

However, such borders are not very effective, they are unobtrusive and bulky
also, the bezel has the potential to impede the driver's or pilot's eye coordination when moving from the instrument panel to the visible exterior view or from the exterior view to the instrument panel

Embodiment Construction

[0044] Referring to Figure 1, a pair of spectacles comprises a frame 1 having two temples 3, on which two lenses 2 are mounted. The term "lens" is as defined above in its ordinary sense.

[0045] Such a mirror may simply be a support for the polarizing filter. In this case, the two faces of the lens are parallel to avoid distortion of the image. It can be an optically correcting lens, and regardless of its specific type of correction (nearsightedness, astigmatism, longsightedness, and presbyopia), it can be a single-focal, afocal, bifocal, trifocal, or variable-focal lens. These lenses can also be connected with other optical mechanisms, such as sunglasses lenses or photochromic mirror lenses.

[0046] The lens 2 is divided into two regions, labeled 2a and 2b. Region 2a is located on the lower side of each lens relative to the position of use of the pair of spectacles. Region 2b is located above region 2a, close to the upper edge of lens 2.

[0047] For each lens 2, the b...

Abstract

The invention concerns a transparent and polarizing viewing element (2) divided into several zones (2a, 2b). At least one of the zones (2a) is associated with a light polarizing filter. The light passing through the optical surface is affected differently for two of said zones (2a, 2b) depending on the polarizing direction of said light. The polarizing filter is obliquely oriented relative to a horizontal direction (H) in the operational position of the element (2; 5), with an angle between the filter orientation and said horizontal direction of 90 degrees and of 0 degree.

Description

technical field [0001] The present invention relates to a transparent polarizing vision element comprising an obliquely oriented polarizing filter attached thereto. Background technique [0002] US 6 250 759 describes a spectacle lens suitable for recreational sports such as golf, hunting or fishing. These lenses are divided into regions whose optical transmission characteristics correspond to the objects and landscapes in these activities. In particular, different regions of these lenses may have different filtering properties according to the polarization of the latter. [0003] The field of view of car pilots, motorcycle pilots and airplane pilots has its own characteristics. In particular, it contains two separate parts. The first part of the field of view, usually the lower part of the field of vision, is occupied by the instrument panel of the vehicle or aircraft. The dashboard usually contains one or more displays, such as of the liquid crystal display type. The ...
