Hard Driving Progressive design focused on distance and intermediate fields, with personalisation and variable inset.
Application and design rationale
Distance and intermediate vision for driving
Hard design with an addition range of 0.75–4.00 D. Coating, tint and driving-filter selection require confirmation of the available configuration.

Design mechanism and features
Prioritising distance and intermediate vision
DriveMax is a Hard Driving Progressive. It emphasises road distance and intermediate tasks such as the dashboard, with a near zone according to the ordered addition.
Fitting for the driving position
Personalisation is active; frame position, BVD and gaze height matter when ordering. The table lists 18 mm NRP and 0–4 mm Core Inset.
Difference from office lenses
WorkMax and WorkUltraMax address near/intermediate office distances within a room; DriveMax addresses driving. Coating, tint and driving requirements must match the actual order.

Technologies in this design
- DuraTrace
- Ray-tracing calculations and optical-aberration optimisation in surface design.
- 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.
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.
