Adaptive progressive with personalisation and variable inset, designed to connect distance, intermediate and near viewing needs.
Application and design rationale
Adaptive design with a variable near corridor
Adaptive design with a 12–18 mm near-reference range allows selection according to fitting height. Corridor and inset must match actual frame dimensions.

Design mechanism and features
Choosing visual-field priorities
OptiMax is Adaptive and its text refers to six user profiles. Driving examples prioritise distance/intermediate vision; reading/tool work prioritise intermediate/near vision. The other four profiles' names and ranges are not specified.
Balancing the viewing zones
Changing visual-field priorities redistributes power and unwanted astigmatism. The aim is to match the principal activity; all zones cannot expand simultaneously without limit.
Calculation and adaptation
DuraTrace handles ray calculations and DuraFit Inset adjusts the near zone. The document also mentions DuraAperture, with NRP 12–18 mm and addition +0.75 to +4.50 D.
Technologies in this design
- DuraTrace
- Ray-tracing calculations and optical-aberration optimisation in surface design.
- DuraFit Inset
- Near-zone inset adjustment; the model's range appears in its specification table.
- DuraAperture
- Considering the effective pupil aperture when calculating viewing zones.
Measure before manufacture
Required parameters vary by design and must be recorded by a professional.
- Monocular PD
- Each eye's pupillary distance is recorded separately to align horizontal lens positioning with the visual axis.
- Fitting Height
- Fitting height is recorded on the adjusted frame in the natural position of wear; the required near zone must also fit within the frame.
- BVD
- Distance from the rear lens surface to the corneal apex; relevant to power-compensation calculations in personalised models.
- Pantoscopic Angle
- The frame's vertical tilt in the position of wear must be measured; example values are not substitutes for measurement.
- Wrap Angle
- The horizontal curvature of the frame relative to the face, describing lens positioning.
- Box A
- Horizontal width of the frame opening in the boxing system.
- Box B
- Vertical height of the frame opening in the boxing system.
- DBL
- Distance between the two lens boxes at the frame bridge.
- ED
- Effective diameter: twice the greatest distance from the boxing centre to the lens-shape edge, used for blank selection and edging calculations.
Design-specific inputs
- Working Distance (near and intermediate): defines the wearer's primary task distance to calibrate power gradient and working depth.
- Corridor Length / NRP Selection (12–18 mm): select corridor length according to frame height (Box B) and the wearer's viewing ergonomics.
- DuraFit Inset (variable 0–4 mm): calculates horizontal displacement of the reading segment from working distance and prescription power.
Monocular pupillary distance
For aligning the lens centre with each eye's visual axis.
Fitting height
Vertical pupil position relative to the frame in the position of wear.
Back vertex distance
One of the inputs describing the actual position of wear.
These are basic fitting parameters; additional inputs and the level of personalisation are specified for each model.
