A method of producing a lens with an embedded foil, comprising the steps of positioning a foil () on a foil fixation holder, providing adhesive attachment dots () on the foil () on surface portions () opposite to the foil fixation holder, positioning the front mould () ensuring the contact of the attachment dots () with a surface () of the front mould (), retracting the foil fixation holder and positioning a back mould () opposite to the front mould (). Then the front mould () and the rear mould () are connected with a sealing bridging element () to build an assembly in order to form a mould cavity () with a pouring opening, wherein the edge () of the foil () is spaced apart () from the bridging element () and the assembly comprises passages between the attachment dots (), the foil () and the front mould backside () allowing pouring a monomer into the entire mould cavity () before curing the monomer and decomposing the assembly as well as cutting the lens with the embedded foil from the polymer block.

Method of producing a lens with an embedded foil

A lens with an embedded foil is produced by positioning a foil on a holder, providing adhesive attachment dots on the foil on surface portions opposite to the holder, positioning a front mould ensuring the contact of the dots with a front mould surface, retracting the holder and positioning a back mould opposite to the front mould. The mould is then connected with a sealing bridge to build an assembly forming a mould cavity with a pouring opening. The edge of the foil is spaced apart from the bridge and the assembly has passages between the dots, the foil, and the front mould surface allowing pouring a monomer into the cavity before curing the monomer, decomposing the assembly and cutting the lens from the polymer block.
