To Behold the Beauty of an Amazing World...

  • Retina Forward Design provides wider visual field for comfortable, effortless viewing.
  • Greater asphericity for a more natural appearance and a slimmer lens profile.
  • Optimized position-of-wear optics for crystal clear, aberration-free (AF) vision.
  • Superior optics in a short corridor design.
  • Available 14mm corridor design for smaller frame sizes

The innovative design of AF Progressive lenses creates a new level of optical performance in progressive multifocal lenses. This exclusive technology, called Retina Forward Design, enhances performance in three ways:

Optimized for the position of wear

Changes in viewing angle, lens tilt, and vertex distance in different positions of gaze create optical aberrations that reduce clarity and comfort. This is especially true with aspheric lenses, which have flatter curves. Since these optical errors are caused by position of wear factors, they are not detected by conventional lensometry.

AF Progressive lenses are specifically designed for how lenses are actually worn. In Retina Forward Design, lens surface power is precisely calculated at 5,000 points on each AF Progressive to optimize optical performance and reduce aberrations caused by pantoscopic tilt, vertex distance variations, and object distance. Though these power adjustments are small, they pay huge dividends by improving image quality at the retina in all directions of gaze for greater clarity and wearing comfort.

Smoother power changes

The surface power optimization of Retina Forward Design gives the AF Progressive smoother power transitions and wider viewing zones. This creates a more natural viewing experience virtually free of swim or distortion.

Slimmer aspheric profile

Retina Forward Design makes it possible for AF Progressive lenses to have a slimmer, more attractive profile without compromising optical performance. Base curves are flattened up to 1.5 diopters to create the slimmest, most attractive lens possible. In plus powers, the flatter curves of AF Progressives also reduce unwanted magnification and give a more natural appearance to the wearer's eyes.

Retina Forward Design Means No Swim!

The position of a lens when worn in front of the eye affects its optical performance. One variable in lens position is vertex distance. Vertex distance is the distance from the back surface of the lens to the apex of the cornea of the eye.

The effective power of lenses changes with vertex distance. With increasing vertex distance, plus lenses effectively get stronger, while minus lenses effectively get weaker. Conversely, when vertex distance is shortened, minus lenses effectively get stronger, while plus lenses effectively get weaker. Therefore, control of vertex distance (or making lens power compensations for changes in vertex distance) is important to maintain the effective power of a lens when it is worn in front of the eye.

Vertex distance also affects field of view. The shorter the vertex distance, the wider field of view. A shorter vertex distance also enhances the cosmetic appearance of eyewear. Therefore, spectacle lenses should be fit with a vertex distance of approximately 12mm. This distance provides wide fields of view and a cosmetically pleasing appearance, while providing adequate separation from the face to prevent the wearer?s eyelashes from touching the back surface of the lens.Pantoscopic Tilt

A second factor that affects the optical performance of a lens is pantoscopic tilt. Pantoscopic tilt is the angle between the plane of the spectacle lens (and frame front) and the frontal plane of the face when the superior edge of the lens is farther away from the frontal plane than the inferior edge. Pantoscopic tilt brings the front of the frame into proper relationship with the wearer?s eyebrows and cheeks. It also provides the widest field of view for reading, since the vertex distance of the lower half of the lens is minimized. However, tilting a lens in front of the eye induces a lens aberration called marginal astigmatism. Pantoscopic tilt changes the effective sphere power of the lens and induces cylinder power at axis 180º. For compound prescriptions with axis other than 180º, pantoscopic tilt changes the effective axis of the cylinder power. And pantoscopic tilt reduces vertex distance for the lower half of the lens, but increases vertex distance above the 180º line.
