technology is a logical extension

f

Design by Prescription. Nova 3di uses high-tech computer-aided ray tracing technology to deliver the most advanced progressive-lens technology in the market. It allows to incorporate specific design onto a lens blank without having to compromise visual acuity, as seen with traditional progressive lens designs. Nova 3di eliminates unwanted radial astigmatic error, the most common cause of non-adaptation in patients with presbyopia.

Instead of producing progressive lenses with external progression and

grinding the spherical and cylindrical powers onto the back of the lens-as was done in the past – the whole prescription of the patient can be applied

n the lens back surface and individually calculated – thanks to freeform

technology.

Analogical to the technology used with

multi-aspherical single vision lenses, Nova 3di eliminates emerging distortions in the far vision zone and in the periphery

f the progressive zone almost entirely
ut of the wearer’s viewing field due to

the calculation of a multitude of single dots on the surface.

SLIDE 4

Everyone’s face is unique and so along with the standard prescription

values for your lenses, individual values are also determined, which can be obtained by only one person- you!

Nova 3di i – Retina ina Forwa ward rd Design ign

You will notice a slight divergence between measured and ordered values

with Nova 3di, due to the fact that we automatically adapt the lens power based on the angle of inclination, BVD and the object distances relevant for different viewing fields.

RFD-lead to clear vision in every lens zone. Conventional Lens-results in

ver/under correction.

Back vertex distance is essential for the quality of the vision, measuring the distance ensures that the lens is tailored for the best level of vision.

Each frame has different curvature and Hence fits differently on the face, hence facial wrap is very critical for individual lenses to minimize distortions.
