Surfacing Room

Digital free form lenses have many advantages over their conventional counterparts: clear vision across the entire surface, from edge-to-edge; compensation to eliminate perceived prism and off axis visual problems; and better contrast perception, low light and night vision.

The free form lens design software (LDS) maps an optimal design to the back of any semi-finished lens blank. This sophisticated design is calculated using consolidated patient data – including prescription, frame, position of wear, focal length, lens material and face form, to name a few. The rendered data model is then precisely machined onto the back surface of the lens by a digital lens generator. This generator uses three and four dimensional diamond tipped digital lens lathes to produce lenses accurate to within 1/100th of a dioptre. The Innovations Lab Management Software (LMS) supports all lens design software vendors.

Advantages

Patients with high or complex prescriptions receive the greatest benefit from the mitigation of oblique aberration, experiencing a pronounced improvement in their field of vision. And, compared to the conventional or front side molded variants, progressive free form lens users enjoy a better field of vision, far easier accommodation, and significantly reduced ‘swim & sway’. Many of these users describing the experience being like wearing single vision spectacles; as they can move from distance, through intermediate and into near vision without experiencing any discernible blurring.
