Award Winning Varifocal freeform lenses give you high-resolution vision.
The difference is immediate – glasses fitted with freeform lenses are very different to glasses fitted with normal varifocal lenses, and eliminate corridor vision.
The design innovation of Freeform is quite staggering giving you more lateral and sharper vision and greater postural comfort |

FREE-FORM GENERATED LENSES BENEFIT EVERYONE!
|
Superior product quality with unprecedented surface smoothness.
Greater wearer comfort and quicker user adaption as compared to traditional, progressive lenses. |

The optical industry is poised for significant change thanks to the introduction of freeform surfacing to the lens manufacturing process. Lens innovations facilitated by this manufacturing breakthrough are already coming to market. One such example is
The transition to freeform technology this is a watershed in the history of eyewear, much like the
transition from bifocals to PALs was a generation ago.
Advances made possible by freeform surfacing will create massive change to varifocals. Practices will want to learn about freeform surfacing now so as to position themselves to take maximum advantage of a technology that will improve patients’ vision and bring a new generation of premium products to market that will significantly improve vision, comfort and wide lens viewing. |

Traditional lens-making tools have either spherical or cylindrical surfaces and can work only on the backside of the lens. They cannot create aspheric shapes or the complex curves required for PAL designs. This is why the progressive channel of PAL designs has traditionally been pre-molded by the manufacturer on the front surface of the lens.
Freeform, or direct, surfacing makes it possible to grind the front, back, or both sides of a lens blank as needed to produce sophisticated lens designs. A computer numerically controlled (CNC) freeform generator creates the lens surface according to the desired parameters, which may include optics influencing variables beyond the usual sphere cylinder, and axis of the prescription.
The lens is then polished, using a computer- controlled “soft sponge” system to ensure optimal clarity is achieved while maintaining the integrity of the surface curves in theory. |

With freeform generation any curve that can be mathematically described can be generated. What is important in practical terms is that freeform generation allows any optically useful design to be created in a spectacle lens. Where manufacturing technology was once the limiting factor in optical design, that barrier has been removed. It is now possible and affordable to offer each patient an optically advanced (even a unique) solution to his or her visual needs. Thus, freeform technology allows manufacturers to take single-vision and multifocal lens designs to higher levels of optical sophistication. |
