METHOD AND DEVICE FOR MOULDING AN OPTICAL LENS, ESPECIALLY AN OPHTHALMIC LENS

摘要

The procedure uses two moulding shells (12, 29) that are positioned at a predetermined distance from one another. The first shell (12) is fixed in a holder (6), and the second one (29) in another holder (27). The first holder is held in a position where its shell's moulding surface faces upwards and forms the bottom of a mould chamber. It is then filled with a predetermined quantity of the polymerizable material, and the second shell is moved towards the first so that its moulding surface is in contact with the polymerizable material and located partially inside the moulding chamber, at a distance from its edges.
