RX Progressive Lenses:
The Next Evolution
in Digital Optics
A comprehensive strategic guide to tiered IOT® progressive solutions. Expertly engineered for high-end optical labs and premium dispensaries worldwide.
IOT® Technology Drives
Optical Superiority
Every progressive lens in our portfolio is built on IOT® (Indizen Optical Technologies, Spain) algorithms -- the same computational framework trusted by leading European labs. Two proprietary methodologies form the foundation of our digital surfacing capability.
Digital Ray-Path 2™
An advanced simulation that considers the unique oblique aberrations of each wearer. By calculating the power at every point of the lens, we eliminate peripheral blur and distortion -- even in complex prescriptions and wrap frames.
Steady Plus™ Methodology
This breakthrough technology strictly controls the mean power in the lateral areas of the lens. The result is unmatched image stability and a significant reduction in the "swim effect" -- the leading cause of progressive lens rejection.
The 4-Tiered Solution Matrix
Select the right progressive tier for each patient profile. Every tier is manufactured in-house on Schneider digital surfacing systems.

Alpha: The Gateway to
Digital Freeform
The Alpha design is our entry-level digital progressive, engineered specifically for patients transitioning from single vision or bifocals. Its "Soft Design" philosophy prioritizes ease of adaptation over sheer corridor width -- delivering clinical confidence to dispensaries and measurable patient satisfaction to labs.
- Optimized for 100% rapid adaptation -- reduced chair time for dispensaries
- Minimal peripheral swimming effect via controlled lateral gradient
- Cost-effective digital back-surface processing on all major index materials
- • First-Time Presbyopes (age 40+): Seeking a seamless and comfortable transition into multifocal vision with low-to-moderate add power.
- • Young Adults & Digital Users: Perfect as an "anti-fatigue" or accommodation support lens for younger demographics experiencing heavy digital screen time and eye strain.

Camber™ Technology:
The Two-Surface Synergy
Camber is the pinnacle of progressive design, combining a unique variable base curve front surface with a precision digital back surface. This patented technology creates an optically ideal curve in every viewing zone -- distance, intermediate, and near.
Unlike standard single-surface blanks, Camber provides a flatter distance zone for natural spatial perception and a steeper near zone for effortless reading -- simultaneously optimized across both surfaces.
"94% of wearers reported near vision quality equal or better than conventional progressive designs."

Technical FAQ
Common B2B Questions
What is the maximum ADD power available?
We process custom ADD powers up to +3.50D with high precision using our D-Free freeform platform. Standard ADD range begins at +0.75D, with increments of 0.25D throughout. For extreme ADD values (+3.00D and above), we recommend MR-8 (1.60) or higher index materials to maintain optimal lens thickness.
Do you supply semi-finished progressive blanks for local Rx labs?
Yes. We supply premium semi-finished progressive blanks optimized for all major freeform generators, including Optotech 4K/8K and Schneider CCP systems. Our OPTIBOND™ blanks feature industry-leading Spin Coating technology and are manufactured from genuine Mitsui MR™ series monomers, ensuring consistent base curve geometry and coating adhesion across your entire production run.
How do you handle extreme customized parameters like Pantoscopic Tilt?
Our system processes exact POW (Position of Wear) measurements for truly personalized visual corridors. This includes Pantoscopic Tilt, Face Form Angle (FFA), and Back Vertex Distance (BVD). These parameters are fed directly into our IOT Spain digital design algorithms, which recalculate the entire lens geometry to compensate for the patient's unique frame-face relationship -- delivering clinically superior outcomes versus standard progressive designs.
