I was conversing with one of our lens reps today about "true free form" lenses. Talking Gradal Individual, Autograph, Ipseo, Hoyalux ID...What she stated was that because of the dual surfacing involved in making a true free form lens, that transitions was incompatable with this process.
According to her sources, those that offer transitions in a "free form" lens are either using a molded lens, or in the case of the Ipseo, only surfacing a small portion of the add on the front (which I thought was good anyway) or somehow is manufacturing a lens that isn't really as customized, correcting for higher order abberations etc...as their lens.
I was curious as to the truthfullness of this statement. Is transitions not compatible with Free form lenses, and are manufacturer's who are trying ot combine the two providing something that either A)isn't double surfaced, or B)less customized than the "clear" product?
