Upper Segment Lenses
DD28 Perform™
DD28 Perform has fully optimized optics in all directions. Including calculations based on frame parameters. Upper Segment can be ordered with same addition as the lower segment or with around 62 %.
| Addition: | Engraving | Default parameters: |
| 1.0-3.0 | Sign: Symbol: | CVD: 13 mm |
| See table below | P ◇ | FFT: 4 degrees |
| for exact range | PT: 6 degrees |
DD28 Atoric™
DD28 Atoric is a back surface atoric design with an individualized aspherization in both meridians for all powers. Optimized calculations for all base curves. Upper Segment can be ordered with same addition as the lower segment or with around 62%.
| Addition: |
| 1.0-3.0 |
| See table below for exact range |
DD28 Classic
DD28 Classic has a spherical design. Upper Segment can be ordered with same addition as the lower segment or with around 62 %.
| Addition: |
| 1.0-3.0 |
| See table below for exact range |
Note that the DD28 lens is symmetric so it can be fitted upside-down to have the lower addition in the lower segment if desired. See the table below for the different combinations of additions.
