In the October 20/20mag LT section, which focuses on different edge finishes, there is a table listing ABBE values of the different lens materials. Poly is listed as having a 45 ABBE value. Is there something that I am missing? Everything I have been taught and researched tells me that poly has an ABBE value of 30. Can someone please elaborate on this? Thanks!
Am I missing something??
