Abstract: A mold unit (22) for molding ophthalmic lenses comprises: an adapter piece (220) comprising an opening (2200) extending around a longitudinal axis (2201); a sleeve (221) fixedly connected to the adapter piece (220) and extending through the opening (2200) of the adapter piece (220); a lens mold (222) rigidly mounted to the sleeve (221); an adjustment ring (224) firmly attached to the sleeve (221) to circumferentially surround a portion of the sleeve (221). The adjustment ring (224) comprises a flat circular outer engagement surface (2244), and the adapter piece (220) comprises at least one clamping block (2211) having a flat inner clamping surface (2214).

Abstract: A packaging container (1) for a contact lens comprises a shell (2). The shell (2) comprises a cavity (10) having a drop-shaped perimeter (12), and a flange (20) having a flat upper surface (22) extending around the drop-shaped perimeter (12) of the cavity (10) in an upper surface plane (24). The cavity (10) comprises a bowl portion (30) including an at least partially spherical section (32) for accommodating the contact lens, and a chamfer portion (40) surrounding the bowl portion (30). The chamfer portion (40) is arranged between the bowl portion (30) and the drop-shaped perimeter (12) of the cavity (10) and includes a tapered outlet section (42) forming a tip towards the flange (20) to facilitate removal of the contact lens from the cavity (10).

Abstract: A method for avoiding the entrapment of air bubbles (5) in a lens forming material, in particular in a low viscosity lens forming material, in an ophthalmic lens manufacturing process using mold halves (2; 3) each having a lens forming surface (21; 31) comprises electrostatically charging a predetermined portion of the lens forming surface (21; 31) of the mold half (2; 3) prior to the predetermined portion of the lens forming surface (21; 31) coming into contact with the lens forming material (4).
