Seiko Optical Products is proud to offer our professional customers thevery best in free-form progressive digital lens surfacing with the SEIKOPerfas 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 andswaying sensations often experienced with progressive lenses.With the prescription on the back of the lens, closer to the eye, thevisual zones are much wider. It’s like looking through the keyhole of anold door lock–the closer your eye gets to the key hole, the more of thenext room you can see.
