Freeform Technology

Free Form uses the latest technology in the production of the world's progressive lens. Lenses now produced with this technology, are not also wonderful cosmetically in appearance but also provide comfort to the wearer thanks to its unique design that surpasses the accuracy outcomes of conventional progessive lens design techniques.

Free Form's technological superiority over the old methods can be grouped under several headings.

Personal progressive:

Personal Free Form technology is produced progressively according to the analysis of the patient's own needs (vertex distance, pupillary aperature, pantoscopic and frame wrap angles).

Surface accuracy:

ISO standards of diopter tolerances are internationally recognized in lens production. Since there are no lens molds used during this production process, lens deformation does not occur. As a result, the wearers prescription accuracy is more exact and higher tolerance acceptance than the conventional progressive process. In summary, thanks to Free Form technology, the most accurate possible prescription information can be achieved from any wearer with just a few added measurement steps during the fitting process.

Wider Field of View:

Since Free Form technology processes the progressive surface to back surface of the lens, the front surface offers a wide peripheral field of view.

Lower image disorders:

In Free Form technology, since no process is done to the front surface of the lens, the total magnification is much less which provides a more natural or realistic eye image size.

A wider range of products:

Since Free Form technology easily brings progressive designs with any desired material together, it provides the industry with an exceptionally large catalog of choices compared to the conventional progressive process.

Formation of Image Disorder

Total Magnification value (M) = Shape Factor (Ms) x diopter Factor (Mp)

Image Disorder Reduction in Free Form Progressive

Total Magnification value (M) = Shape Factor (Ms) x diopter Factor (Mp)

Comparison of Image Disorder in Progressive lenses

In Free Form Progressives, magnification is significantly reduced in the lens.
  • Significant reduction of size image disorders
  • Significant reduction of the image disorders in lateral area
  • Significant decrease in peripheral blur

Expansion of the field of vision in FreeForm Progressive

In Free Form Progressives, the field of view is approximately 30% larger than conventional design progressives and approximately 15% improvement in left and right lateral areas, respectively.

Astigmatic Area Formation according to the frame Parameters
Conventional Surfaced Progressive

When + 2.00 -1.00 lens prescription is assembled in a frame with 10 degrees of vertex angle the result causes 20% more unwanted astigmatism. However, via the handicaps created by Freeform technology framework will be eliminated by more detailed calculations and custom software control.

Conventional progressive technology's big shortfall in lens production was that it would only produce optical lenses based on the full power of refracters phoroptor. When vertex distance is provided and manufactured in the final lens product, light is redirected and shows significant positive results.

Advantages of symmetrical binocular vision = Complete Satisfactionı

As the head moves from a fixed distance object to the left, the lens clarity in the right eye would normally become blurred. With Novax Freeform progressives, horizontal head movement and visual clarity is unaffected with its exceptional design symmetry.

Backside Processing Advantage

In Freeform technology, only the rear surface treatment is a factor sight that increases the comfort. In the other case, ie when used double-surface map, the light on the front creates a road map to a deviation of 7% on the back surface layer causing obstacles to the processing of the desired map.

Personalized freefrom Single Vision Technology – Asfera

In single vision glasses, when the number increases, the edge areas consist astigmatic deviations. In tailor-made freeform unifocal lenses (Asfera) , not only in the central part of glass but also in the external field is provided a clear vision.
