Abstract
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.
