Kriptok (bifocal) lenses work within these ranges:
| SPHLens power | CYLAstigmatism | ADDReading | |
|---|---|---|---|
| Kriptok | 0.00 to -6.00 | up to -4.00 | +1.00 to +3.00 |
The visible line is normal. It marks where the reading power starts. Some frames with very small lenses may not suit Kriptok; we’ll check fit in store.
