We use the frame shape number for a few different things. The first thing we do with the frame shape number is to build the shape with the A and B measurements provided.
After we have done this, we will calculate the ED based on the new shape. Why do we do this?
Lets take this job for example. I have a +2.50 -1.50, with a 58 PD in a 53-21 Drill mount frame.

Frame Measurements have become increasingly important with the addition of digital lens designs. As a lab, we have lost control over the safety margin on lens cutout. The lens designer gives us all of the parameters to process the lens, and we are at their mercy.
Our biggest issue has been the Frame ED (Effective Diameter) measurement. Unfortunately, many have been misinformed about how to measure this.
When we get a job that hasn’t cut out for a customer, what we often see is the LD, or Longest Diameter, placed incorrectly in the ED box. One of the top results in a quick Google search even incorrectly explains how to measure it.

You probably get a lot of questions in your practice during patients' eye exams. Many questions come up about the different types of lenses. Many people are asking questions about the difference between bifocal and progressive lenses. If your patients are asking the same questions, here are some suggestions on how to answer that will help eliminate their confusion, and hopefully, provide you with some additional revenue. That’s a win-win!
