In the early history of Persol, when the
glasses were produced in small volumes, the company also offered more
than four different sizes for each pair of glasses, bridges of various
heights and widths and arms of various lengths – all in the name of
making each pair of glasses essentially “made to measure” so they
would be as comfortable as possible.
Particular care is still devoted to evenly
distribute the weight of the glasses across their entire surface through
a special process called “telatura” that consists of eliminating
edges on the underside of the bridge to make the fit more comfortable.
This manual process was first introduced when Persol founder Giuseppi
Ratti still ran the company and is still applied with the same precision
and attention today.
comfort also led Persol to create a foldable acetate frame in the 1960s,
perhaps the first of its kind.
