UltraMax SV
Single vision personalised to viewing behaviour
Explore design and specificationsUltraMax SV is single vision, combining frame geometry with eye/head movement data. DuraTrace and DuraTrack underpin this personalised approach.
Application and design rationale
Viewing behaviour alongside frame geometry
Unlike single-vision designs relying on frame parameters, this model also considers eye/head movement. DuraTrack supplies viewing-behaviour data and DuraTrace provides optical calculations.

Design mechanism and features
Two levels of personalisation
UltraMax SV uses viewing-behaviour data alongside frame positioning in single-vision design. The document identifies DuraTrace for ray calculations and DuraTrack for eye/head movement data.
Difference from FlexMax SV
FlexMax SV focuses on compensating frame geometry/position; UltraMax SV additionally uses eye/head behaviour. This is an input difference, not a guarantee of zero aberrations or immediate adaptation.
Technologies in this design
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.
