    Abstract: The mold has a circular shaped molding cavity (10) having a geometrical center and a main plane (XX, D1), and a sprue base (11), having a longitudinal axis (YY), injecting a liquid polymerizable composition in the cavity. The base has a molding sill (12) in communication with the cavity by a supplying connection (20). The longitudinal axis and the center define a plane orthogonal to the main plane, where the axis makes an angle, from zero to fifteen degrees, with the main plane of the cavity. An independent claim is also included for a method for reaction injection molding of a part e.g. optical component such as an ophthalmic lens, using a mold.

    Abstract: A disk enabling modification of the power of an optical component consists of a Fresnel lens. The disk is initially formed with a general rounded shape which corresponds to the shape of the optical component. In this way, the disk does not lose its shape or does not lose it very much when it is applied against the component. It does not cause image distortion or optical aberration when an object is observed through the component provided with the disk. Such a disk is particularly adapted to obtain correction of ametropia or to a solar mask initially lacking optical power.

    Abstract: The assembly has an ophthalmic lens (1), and a support (4) on which the lens is mounted and including studs (6) for maintaining the lens through its circular edge (2). A notch (3) formed in the circular edge presents a U-shaped section and extends through the height of the circular edge. The lens is centered by cooperating the edge with the studs and is indexed angularly by engaging one of the studs in the notch. An independent claim is also included for a method of treating an ophthalmic lens.
