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.
Most importantly, Perfas lenses provide outstanding optical performance because they are custom made to your exact prescription without the use of pre-molded blanks like conventional progressive lenses. All the elements of the prescription (sphere, cylinder axis, add power and/or prism) are placed on the back surface of the lens. The result is just what the doctor ordered?a truly accurate prescription that is custom made to your patient's exact visual needs.
