Premium Lenses

Unique Customization

Free-form is only a manufacturing process, not a design process. Impression, Impression FreeSign and MyView lenses are designed only after collecting the patient's Rx, individual PD (MyView), frame parameters (Impression), and visual demands (Impression FreeSign). This proprietary design software calculates the entire progressive surface based on this information, resulting in the most customized and individualized lenses available today.

Rodenstock

The Rodenstock brand continues to stand for products that satisfy the highest technological demands. In 2000, Rodenstock introduced Impression ILT, the world's first truly individualized progressive lens. Impression considered more fitting data than any other lens on the market--Pantoscopic Tilt, Vertex Distance, Frame Wrap and Pupil Distances. Today as a result of our unwavering belief that these are the most important design factors in progressive lens design, Position Of Wear and the ability to design the lens based on these factors, we are proud to announce a completely re-designed lens portfolio. Progressiv PureLife Optimized for Far and Near Vision Points | Released September 2008 Rodenstock has collected MILLIONS of "data sets" while producing Impression lenses and completely re-designed a "classic" progressive lens. The new set of standards will prove to make this the most comfortable progressive lens today, only to be outperformed by a truly INDIVIDUALIZED progressive lens. MyView Optimized for the Whole Lens Surface | Released January 2008 Now with MyView patients are fit to individual pupil distances that were previously only available at the Impression price point! MyView is designed only AFTER receiving your patient's prescription and pupil distances, using proprietary software. Impression Optimized for the Whole Lens Surface and Frame Fit | Released April 2000 This lens remains to set the standard for others to reach. Truly INDIVIDUALIZED based on the patient, the frame selection, and the patient's actual prescription. Although released in 2000, only now are we seeing our competitors introducing lenses that consider these factors (Vertex Distance, Pantoscopic Tilt, Frame Wrap and PDs). Impression FreeSign Optimized for People | Released in Germany 2008/Available in Canada Early 2009 Another innovation from Rodenstock! For the first-time ever a progressive lens that gives you, the eyecare professional, the ability to customize progressive properties according to your patient's visual habits and demands. FreeSign is designed based on all the factors considered with Impression combined with cutting-edge software. You can consult with your patient to determine their main vision zones and adjust them accordingly, now you are the lens designer! Rodenstock will continue to be pioneers and lead the industry with innovative and technologically advanced progressive lens designs. If you want to see what our competitors will be doing tomorrow, look at what we are doing today! Sincerely, Tom Scott National Lens Division Manager
