Hi everybody,
some time ago I saw a clear printed "sticky" film, being used to help the optician or technician to find the distance and reading zone on "unstamped" progressives. Just with the help of the engravings, the film would be placed on the lens, and, if you had the right print pattern on the film (matching film pattern and lens type) it would correctly encircle the two areas i.e. distance and near to read with the vertometer.
This allowed to re-check a pair on site at any time later, when the factory stamp had been removed.
Who has seen this recently and any idea where to get this film from or made to order ?
