Semif lens1

What’s the importance of a good semi-finished lens to RX production?..
a. High qualified rate in power accuracy and stability
b. High qualified rate in cosmetics quality
c. High optical features
d. Good tinting effects and hard-coating/AR coating results
e. Realize the maximum production capacity
f. Punctual delivery
Not just superficial quality, semi-finished lenses are more focus on the internal quality, such as precise and stable parameters, especially for the popular freeform

1) The most popular fused bifocal today has a D-shaped near segment rotated 90 degrees so that the flat part of the “D” is facing up. For this reason, D-seg bifocals also are called “flat-top” (FT) or “straight-top” (ST) bifocals.

2) This is a D segment bifocal lens. It has the benefit that the optical centre of the near vision part of the lens i.e. the part of the reading area which gives the very best vision, is situated at the top of the reading portion. Also the widest part of the reading area is just below the dividing line, and is the part of the lens the wearer would use.
