Semi Finished Lenses
Semi-finished lens is the raw blank used to produce the most individualized RX lens according to thepatient’s prescription. Different prescription powers request for different semi-finished lens types or base curves.
The semi-finished lenses are produced in a casting process. Here, liquid monomers are first poured into moulds. Various substances are added to the monomers, e.g. initiators and UV absorbers. The initiator triggers a chemical reaction that leads to hardening or “curing” of the lens, while the UV absorber increases the UV absorption of the lenses and prevents yellowing.
