Product Information
Okay, here’s the skinny. Autograph II® is a Freeform® lens. Still not quite sure what the differences between semi-finished PALs and Freeform® PALs are? We’ve got you covered... semi-finished progressives are made when the progressive lens design is cast into a mold, the design is on the front and the patient’s Rx is later ground onto the back of the lens.

Made at the lab, Freeform® lenses start from a single vision blank and are ground with precision using special machines. The design and the patient’s Rx are on the back of the lens.
Yes! Semi-finished lenses are all created from a mold. While the first lens cast from the mold is “perfect,” through time the mold slowly suffers from slight degradations and ultimately the design isn’t as “perfect” as it was in the first batch.
Product Information (Continued...)
This loss of optical design does not occur in Freeform® lenses, such as Autograph II®, because each one is created from a Freeform® machine, right on the spot and not from a 20th century mold. The lens is also personalized to fit the patient’s needs and both the patient’s Rx and the optical design are on the back of the lens which opens up the fields of vision for the patient.
