Abstract
There is described a method of dosing a lens forming material into a mold (), which comprises dosing a metered amount of a lens forming material (P) including a volatile solvent into a mold cavity () enclosed by a female mold half () and a male mold half of a mold (). The lens forming material (P) is subsequently polymerized and/or cross-linked to form an ophthalmic lens, in particular a contact lens. Dosing of the lens forming material (P) into the mold cavity () is accomplished while the mold halves () are associated with each other substantially gas-tight. There is also described an apparatus for carrying out the method.
