Abstract
According to a process for manufacturing a series of ophthalmic lenses, each lens consists of a substrate and a film portion () attached to the substrate. The characteristics specific to each lens are obtained by functionalizing the film portion. Film functionalization is carried out when the film is in the form of a large planar sheet (), and then each portion is cut from the sheet. To obtain economic lens manufacture, with a good production yield, the film portions have, right from the start of the process, dimensions corresponding substantially to the housing of a frame into which each lens is intended to be fitted.
