The lens has a lens body (11) of a homogeneous, transparent plastic provided with mountings engaging over the pupillary edge of the iris for fastening on the iris. The lens body and its mountings are made of an elastomeric silicone rubber or silicone resin the specific gravity of which approximately corresponds to that of the aqueous humour or is slightly above that. Two annular discs (15, 16; 15', 16') between which an annular space (19), which widens toward the outside and is hollowed in the region adjoining the lens body, for accommodation of the edge of the iris sit on the circumferential area (14) of the central lens body. <IMAGE> |
