Casting mold half and casting mold for producing contact lenses
摘要:
A casting mold half (5, 5a) for producing contact lenses comprises a mount (50) and an insert (51, 51a), which is arranged at one end of the mount (50) and can be connected to the mount (50) and which has a shaping surface (510) for the shaping of the front or rear surface of the contact lens to be produced. The insert (51, 51a) consists in the region of the shaping surface (510) of a material which is permeable to the energy crosslinking the starting material of the contact lens. Finally, a mask made of a material impermeable to the energy crosslinking the starting material is provided for spatially delimiting this energy. The mask comprises a separate surround (512) made of a material impermeable to the energy crosslinking the starting material of the contact lens, which surrounds the edge region of the shaping surface (510) of the insert (51, 51a).
