I'm trying to find the specs on Essilor's Litestyle and Ultralitestyle lenses? I'm looking for a patient that has a -4.00 OU rx and would like Transitions Xtraactive in one of the trendy larger plastics (from the new Boss Orange line, and it's so beautiful :) )and I'm trying to decide if it'd be better to use a plastic 1.67 or an ultralitestyle from an Essilor lab. I've used a freeform Autograph 1.67 that was really nice, but the indoor tint in the xtraactive was darker than I'd like. Just based on index and abbe value, the 1.67 seems like a better choice, but I'm having trouble finding the specs on the ultra/litestyle materials. Oh, and the frame is plastic 51-17-140, B 35, ED 51. Of course, she's looking for the best optics at the best cost and efficiency. We'll be using a Crizal Easy AR, too.
Thanks in advance.
