We have an 8x11" blue booklet in our store printed in '93, titled "Troubleshooting Progressive Lenses", by Optical Laboratories Association. It has several pages of logo/markings identifier pictures to figure out what lens design a new patient has been wearing....does anyone have a source for an updated version of this booklet featuring the newer lenses? (At the back of the booklet are pages for dealing with specific fitting problems...we have used it for a training supplement.) I really need a more recent version. Can anyone help with a source/address?
