I am not really sure how to ask this or what exactly I am asking for. I need to know if frame manufacturers provide specs for edging lenses. I was told they used to have a book or catalog but I figured it would be online now if available at al. Example would if I am going to edge lenses for a Ray Ban 1588 in a 47 eye would Ray Ban provide the A, B ED and lens circumferences needed to edge the lenses? I have been getting some over sized lenses and would like to be able to verify some frame measurements and such to make sure that is not the issue.
