Abstract: A lens has at least one insert (16, 28), which defines an optical path. For manufacturing the lens, the insert is first bonded to an overmould (36). A polymer (44) is then moulded in a mould (42, 36) formed on one of its faces from the overmould. After moulding, the overmould may be preserved and form part of the lens, if necessary after surface grinding. The overmould may also be separated from the lens; in this case, the lens is machined, removing at least part of the inserts. The lens obtained has an insert in a reproducible position, with an entrance or exit surface inducing no optical distortion.
