Hard design prioritising distance vision with optional personalisation, alongside intermediate and near zones for everyday use.
Application and design rationale
Distance vision first
FarMax is described as Hard; its priorities differ from Soft designs. Personalisation is optional and must be specified when ordering.

Design mechanism and features
Hard profile and viewing-zone priorities
FarMax is Hard. Its description prioritises distance/near zones and concentrates peripheral-astigmatism changes in a tighter area around the corridor. Width-increase claims without comparison conditions do not guarantee results for every order.
Optional personalisation
Unlike models with Personalization: Yes, FarMax personalisation is optional. In the personalised configuration, frame-position data is added to the order. DuraTrace, optional DuraBase and Core Inset are mentioned.
Choosing corridor length
NRP options are listed separately as 12, 13, 15 and 17 mm. Do not replace these four choices with a continuous range or IntroMax options.

Technologies in this design
- DuraTrace
- Ray-tracing calculations and optical-aberration optimisation in surface design.
- DuraBase Optional
- Nominal-power calculations; also described as Nominal Power in the sources.
- Core Inset
- Standard automatic inset for near-zone positioning, as specified in the product 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
- Core Inset (0–4 mm): automatic near-focus shift according to the prescription and reading distance.
- Corridor Selection: manual or automatic NRP depth selection at 12, 13, 15 or 17 mm according to frame form and viewing behaviour.
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.
