Design Notes
Optics
3-Zone Progressive design, center-near, optimized for 7 biometrics including pupil size, higher-order aberrations, axial length and residual accommodation, across 9 critical distances.
Geometry
On the -3.00D HIGH ADD power profile the near band runs from the lens center out to roughly 0.8 mm radial displacement, intermediate from roughly 1.1 mm, and distance from roughly 2.6 mm.
Add
Two powers across the entire power range, Low +0.75D to +1.50D and High +1.75D to +2.50D, taken from the spectacle add.
Surface
Patented Dehydration Barrier, in which poloxamer 407 drives to the lens surface to lock in moisture and mimics the lipid layer of the tear film for a smooth optical surface.
Wetting agent
Polyvinylpyrrolidone (PVP), the hydrophilic polymer that carries the lens water content, matching that of the cornea.
Study
Online survey of patients who wore trial lenses for 4 or more days, top 3-box on a 6-point agreement scale: 91% agreed vision was clear using a mobile phone, 96% on a computer and 95% when driving, n=261.
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. |
