Anti-Fatigue design with near-power steps of 0.50, 0.75 and 0.90 D in the product sheet; selection depends on prescription and professional assessment.
Application and design rationale
Limited support in the lower lens
Its three steps of 0.50, 0.75 and 0.90 D distinguish this model from ReadMax and RestMax. Its dedicated catalogue table confirms personalisation.

Design mechanism and features
Three steps of near-work support
DigiMax is described as Medium Anti-Fatigue and Full Field Progressive. Power Correction values are 0.50, 0.75 and 0.90 D, selected from prescription/accommodation assessment rather than age alone.
Technology and reference-point positioning
The document identifies DuraBase / Nominal Power and Core Inset. DRP and LRP both coincide with PRP. The dedicated table omits NRP/corridor length; 14 mm from a comparison table is not treated as definitive.
Personalisation
DigiMax's dedicated table states Personalization: Yes; the RestMax/YoungMax comparison table says No. This page and its comparisons follow the dedicated DigiMax table.

Technologies in this design
- DuraBase
- 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): calculated horizontal shift of the lower lens according to physiological convergence.

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.
