In the past few months we have sold a couple of Pentax AF Mini's. One of my coworkers asked why they included a card with vertometer readings different from what was ordered. The card stated that they were a progressive with "Retina Forward Design." The Rx was for plus power on top with a 2.25 add and I noticed the actual ground powers noted on the card and read off the lens were slightly different from the original job order (One of the Add Powers read almost .25 stronger.)
Does anyone here want to elaborate on how Retina Forward Design compensates for Progressive lens design issues?
