    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.

    Abstract: Método de desbloqueo de un componente (1) de lente fijado en un bloque (2) termoplástico de un bloque de lente oftálmica, que comprende las etapas de: a) aplicar un esfuerzo de empuje sobre la superficie (14) del componente (1) de lente fijado sobre el bloque (2) termoplástico, b) proporcionar un flujo de gas caliente en la superficie de contacto entre el componente (1) de lente y el bloque (2) termoplástico, caracterizado porque se mantiene el esfuerzo de empuje durante la provisión del flujo de gas caliente en la superficie de contacto entre el componente (1) de lente y el bloque (2) termoplástico, en el que la tensión aplicada para obtener el esfuerzo de empuje de la etapa a) es mayor o igual a 0,1 MPa y menor o igual a 1 MPa y en el que la temperatura del flujo de gas caliente de la etapa b) es mayor o igual a 30º y menor o igual a 70ºC.

    Abstract: The apparatus, comprising two shells forming a moulding cavity, and a closer with a wall (123) of a synthetic material making contact with the two shells and made with an inlet channel (125) for the moulding material. The closer has a joint (40) of an elastomer material forming the contact wall, and the inlet channel is made in a rigid insert (43) that is at least partly over-moulded by the elastomer material. The outlet aperture (126) of the channel is in the shape of a buttonhole as it tapers from one end to the other, and the overmoulding includes a lining of constant thickness.
