progressive of the future.

Nucleo 4D which has a unique innovative front surface design offers even more custom made solutions to each patient with the enhanced calculation parameter technique.

Nucleo 4D’s special raw material gets attention by providing the optically ideal base curve in all viewing zones, innovative adjusting base curve and new front surface design. Special patented raw materials in the making of Nucleo 4D also offers continuously increasing base curve, ideal for the increasing power profile of free form progressive lenses.

It is evident Nucleo 4D’s base curve continually increases from top to bottom when you take a look at the front surface. This improved front surface profile gives each viewing zone a base curve that is well-suited to its function. This increasing curve that is defined by ‘Stacking of The Spheres’ is one of a kind feature to Nucleo 4D in which the diopter is lower in the distance zone, while the diopter is higher in the reading zone.




Front Surface Innovation

Nucleo 4D lens blank features a variable base curve — a new front surface innovation that provides the optically ideal base curve in all viewing zones.



Single Vision Blank

The single vision lens blank has one
base curve from top to bottom.

Nucleo 4D Blank

The Camber lens blank has a patented, continuously
increasing base curve, ideal for the increasing power
profile of free-form progressive lenses.
Each Nucleo 4D lens blank comes from a section of the "Elephant's Trunk" curve, creating a unique variable base curve front surface that
continually increases in diopter from top to bottom. This improved front surface profile gives each viewing zone a base curve that is well-suited to its function.



Variable Base Curve

The radius of the blank continually decreases from top to bottom.

Stacking Of The Spheres

Increasing Curve

The Nucleo 4D front surface features an increasing base curve from top to bottom: lower diopter in the distance zone, higher diopter in the reading zone.
This "stacking of the spheres" is a totally new idea, unique to Nucleo 4D lenses. From the top of the lens blank to the bottom, the base curve increases up to three diopters. This "stacking of the spheres" is a totally new idea, unique to Nucleo 4D lenses.

This new front surface innovation provides benefits to wearers in both the distance and near zones. Wearers enjoy noticeably increased acuity in the periphery of the distance zone, as well as a reading area that is more comfortable and easier to find with the eye.
