Abstract

The present invention relates to a method for manufacturing an ophthalmic article comprising a lens substrate and an ophthalmic wafer wherein the ophthalmic wafer has a blunt edge between a first surface thereof and its lateral surface; wherein the method comprises: providing (S100) the ophthalmic wafer; forming a mold cavity (S200); filling (S300) the mold cavity with a polymerizable composition; and curing (S400) the polymerizable composition to harden it, thus forming the lens substrate thereby obtaining the ophthalmic article. The present invention also relates to ophthalmic article (1) comprising: a lens substrate (12) and an ophthalmic wafer (11) with a first surface (111) in contact with the lens substrate (12), a second surface (112) opposite the first surface (111) and a lateral surface (113) joining the first surface (111) and the second surface (112), the ophthalmic wafer (11) having a blunt edge (113) between the first surface (111) and the lateral surface (112).
