Soft design with several near-reference positions and DuraFit Inset, for consideration across varied everyday needs.
Application and design rationale
Several fitting-height options
Four near-reference choices are listed: 12, 14, 16 and 18 mm. Soft design, personalisation and variable inset are defining features of this model.

Design mechanism and features
Soft profile
IntroMax is described as distributing power changes and unwanted astigmatism more softly across a wider peripheral area. The aim is a gentler visual transition; individual adaptation still varies.
Difference from FarMax
FarMax is Hard with optional personalisation; IntroMax is Soft with Personalization: Yes. This affects viewing-field distribution priorities and manufacturing inputs.
Corridor and inset
IntroMax offers NRPs of 12, 14, 16 and 18 mm with DuraFit Inset. FarMax offers 12, 13, 15 and 17 mm with Core Inset.

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
- DuraFit Inset (0–4 mm): dynamic calculation of horizontal near-segment shift based on distance power and eye convergence.
- NRP Selection: choose among four corridor steps (12, 14, 16 and 18 mm) according to frame height and wearer comfort.

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.
