I have a physio 360 job that just came back from our lab. As I was checking it in, I found that the seg ht which should have been 19 is only 17. Now when I get these progressives in, the markings are not left on the lenses, so I have to use the Progressive Lens Identifier book to mark the lenses to check PD and seg ht. And measuring from the '+' the seg is only measuring 17. The lowest seg for this lens is 17, and even at that most of the reading area is cut off. Is the Prog Lens ID'er book accurate enough in it's diagram to make this call and send it back.
