What Exactly is Free Form?

Free-Form is the state-of-the-art technology that has revolutionized the way ophthalmic lenses are made. Also known as digital, internal, and even backside technology, these terms for Free-Form can refer to the lens design, the tooling or the manufacturing-surfacing technology. Thus, many lenses can all be called Free-Form. From a purist point of view, not all Free-Form lenses are created equal. Free-Form manufactured molds are used to make lens blanks for conventional progressive lenses. For a superior Free-Form lens, you need both a great design and a great surfacing technology. VCD Labs has surveyed all the worldwide manufacturers and designs and has put together a carefully chosen portfolio of proprietary designs to cover all the technical, visual and economic parameters to fit the needs of every patient.

Digital free-form lenses fall into two basic categories:

Optimized

This lens design is optimized to provide the best possible optics, progression of add power and width of the progressive channel.

Design and manufacturing of these lenses takes into consideration the following parameters:

  • Sphere power
  • Cylinder power
  • Axis
  • Add power
  • Prism

Optimized designs maximize the full Rx only. While superior to traditionally fabricated lenses, they do not incorporate any calculations based on the frame requirements or face geometry.
