Design Notes
Optics
3-Zone Progressive design, one continuously descending power curve with the near zone at the lens center, the intermediate zone beginning just past the 1.0 mm tick and the distance zone just past the 2.5 mm tick, plotted across 3.0 mm of radial displacement at -3.00D high add.
Optical design
Optimized for 7 biometrics: pupil size, anterior chamber depth, higher-order aberrations, axial length, corneal topography and diameter, residual accommodation across 9 distances, and subjective refraction.
Add
Two lens adds across the entire power range, selected from the spectacle add: Low for +0.75D to +1.50D and High for +1.75D to +2.50D.
Stabilization
OpticAlign design, ballasting in the lower hemisphere, with the orientation mark at 6 o'clock.
Wetting agent
Polyvinylpyrrolidone (PVP), grown around and throughout the silicone backbone in the second phase of the MoistureSeal polymerization, where it attracts moisture.
Initial Fitting Guide
| Spectacle Add | Lens Selection |
|---|---|
| +0.75D to +1.50D | LOW OU |
| +1.75D to +2.50D | HIGH OU |
Troubleshooting — Poor Near
| Condition | Action |
|---|---|
| Wearing two LOW | Replace Non-Dom with HIGH. If still poor, add +0.25D to Non-Dom. |
| Wearing two HIGH | Add +0.25D to Non-Dom. |
Troubleshooting — Poor Distance
| Condition | Action |
|---|---|
| Wearing two LOW | Replace Dom with single vision lens. |
| Wearing two HIGH | Replace Dom with LOW. |
