Said scraper element (6) comprises a bending area (8) and the cross-sectional surface of the scraper body (6) in the bending region area (8) is smaller than in the region of the scraper edge (7).

The hinge body has attachment edges and a flexing zone (44) between the attachment edges defining a flexing axis (47) .

The absorption of energy is accomplished by incorporation of a flex area in the attachment device.

Various materials and structures that may be included to impart circular bending stiffness within a Front Hip Flex Zone are disclosed.

The inventive shackle spring (1, 1') is provided with at least one second bending area enabling said mechanical stress to be divided up amongst the two bending areas.

The tensile member (60) defines a flexion area (65) that promotes flexing of a first portion (64a) of the bladder with respect to a second portion (63b) of the bladder.

Excellent comfort due to increased useful flexing zone.

Excellent comfort due to the increased useful flexing zone.

The blending zone gradually transitions the curvatures of the central and peripheral zones to further smoothen out the central-to-peripheral-zone transition.

The flexion area is an area where the tensile member is absent, and the flexion area may have the configuration of a space, aperture, or indentation, for example.

Ophthalmic lenses for correcting astigmatism having a posterior surface with a central optic zone, a peripheral zone, and a blending zone therebetween.
