1.56 Semi-Finished Progressive Lens

Progressive lens are line-free multifocals that have a seamless progression of added magnifying power for intermediate and near vision.The starting point for freeform production is a semi-finished lens, also known as a puck due to its resemblance to an ice hockey puck. These are produced in a casting process that is also used to manufacture stock lens. The semi-finished lens 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 lens and prevents yellowing.
