Table 1 Overview of the difference in function between progressive lenses and office lenses
Progressive lens | ZEISS Officelens | |
|---|---|---|
Depth of field | Unlimited depth of field, clear vision at every viewing distance | Clear vision at near and intermediate viewing distance |
Intermediate and near zone | Small intermediate and near zone to offer large distance zone for uninterrupted far vision and dynamic vision | Large near and intermediate zones |
Gaze stabilisation | Gaze stabilization may take longer due to difficulties finding the areas of optimal focus | Superior balance of optics because lens design has a larger available lens area - no distance zone necessary |
Viewing distance | Unlimited maximum viewing distance > 6 m | Limited viewing distance to 1 m, 2 m or 4 m |
Addition power | Full change in addition power needed | No full change in addition power needed |
