Mimics the lens edge design but creates a high luster on the edge of the lens.
Polishing Wheel
Creates the final lens edge design (flat or beveled edge).

layout/block the spotted lens
set up the edger with job parameters
edge the lens
clean and insert/mount lens in frame

To determine the A and B dimensions of the frame.
To gather shape data and transfer it to a patternless edger at a wholesale lab.
To determine the DBL of the frame.
To gather shape data and transfer it to a patternless edger directly wired to that edger.
To allow the collection of three-dimensional frame information to better locate the bevel onthe edge of the lens
Functions of frame tracer
Measuring the A dimension of the pattern
Pattern’s size is determined by
First patternless edger in US
1987
Patterned edger invented in
Early 1900’s
