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.

Description

As people age, they may find that their eyes are not adjusting to distances as they used to. When people inch closer to forty, the lens of the eyes begin to lose flexibility. It becomes difficult to focus on close objects. This condition is called presbyopia. It can be managed to a large extent with the use of bifocals.
Bifocal (also can be called Multifocal) eyeglass lenses contain two or more lens powers to help you see objects at all distances after you lose the ability to naturally change the focus of your eyes due to age.

The lower half of a bifocal lens contains the near segment for reading and other close-up tasks. The rest of the lens is usually a distance correction, but sometimes has no correction at all in it, if you have good distance vision.

When people inch closer to forty, they may find that their eyes are not adjusting to distances as they used to, the lens of the eyes begin to lose flexibility. It becomes difficult to focus on close objects. This condition is called presbyopia. It can be managed to a large extent with the use of bifocals.
