Digital Lenses
Custom made for the way you view the world.
Seiko Optical Products is proud to offer our professional customers
the
very best in free-form progressive digital lens surfacing
with the SEIKO
Perfas family of progressive addition (no-line
multifocal) lenses.
SEIKO Perfas lenses use patented 100%
back-surface free-form lens technology to process the patient’s
entire prescription onto the back surface of the lens. This
technology provides benefits to the wearer which simply cannot
be matched by any conventionally manufactured designs.
Perfas back surface design effectively eliminates the swimming
and
swaying sensations often experienced with progressive lenses.
With
the prescription on the back of the lens, closer to the eye, the
visual
zones are much wider. It’s like looking through the keyhole of
an
old door lock–the closer your eye gets to the key hole, the
more of the
next room you can see.
