I am a freelance optician working in an office with an essilor alpha edger. The owner has left for vacation and (as ussual) forgot to leave me a manual. I have worked with several other essilor edgers. They all had sub-menus for onscreen layout. I have no problem with SV and Prog. lenses. I cant find a layout screen for FT Bifocals. He told me to pre-layout the lenses 5 in & 5 down. I have done this many times before with a briot, weco & santinelli but not on an essilor. Would it not be easier to just layout the bifocal the center point of the seg and edge it as a SV lens? Please let me know if I am on the right track. Thank you in advance from a new-comer to this site.
