The next t developm lopmen ent t step ep in Progres ressiv ive e lens nses es F ree-form technology is a logical extension of 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. Fabul ulous us! Experi erienc ence e a three ee dimensio nsional nal vision.
Freeform eform T echn hnolo ology gy with h Nova 3di I nstead 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 on the lens back surface and individually calculated – thanks to freeform technology. A nalogical to the technology used with multi-aspherical single vision lenses, Nova 3di eliminates emerging distortions in the far vision zone and in the periphery of the progressive zone almost entirely out of the wearer’s viewing field due to the calculation of a multitude of single dots on the surface.
Every y indi divid vidual al is uniqu ique E veryone’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!
