Adaptive progressive with DuraTrace and a variable near corridor; design and fitting are selected according to prescription and visual needs.
Application and design rationale
Aligning design with visual needs
This progressive is described as Adaptive, with an 11–17 mm near reference. Reading distance and fitting height matter when choosing the final design.

Design mechanism and features
Adapting to presbyopic needs
AgeMax is Adaptive, with its description considering presbyopia stage and addition. It focuses on balanced intermediate/near access according to individual needs; age alone does not determine selection.
Shorter NRP range
AgeMax's NRP is 11–17 mm; SuperMax and UltraMax Progressive specify 12–18 mm. Assess the difference against frame dimensions and gaze path during fitting.
DuraTrace calculations
DuraTrace manages oblique-gaze errors, while DuraFit Inset adjusts the near zone within a 0–4 mm range.
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.
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
- Corridor Length / NRP Selection (11–17 mm): choose reading-point depth according to addition, age and frame height, providing 1 mm earlier access than the 12–18 mm corridor.
- DuraFit Inset (variable 0–4 mm): calculates convergence according to distance prescription, addition and reading distance.
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.
