3. OPTICAL TRACING
Preparing optical tracing of demo or recut lens
This type of tracing makes it possible to retrieve the existing shape and drilling data of a lens.
In the case of demo lens tracing, in order not to make a centering error, make sure to use a new
commercially identical lens (brand, logo etc).
The use of lensmeter marking points
guarantees the feature’s horizontality.
A free-hand marking does not to guarantee the
proper horizontality of the feature.
Prerequisite: for the tracer to correctly detect the horizontality of the lens, the lens must be clean and
marked using a white felt tip marker with:
• Either three focimeter dots,
• Or a horizontal line which must not touch the edges of the lens (a space of at least 5 mm is required).
Avoid using red markers
