How Bifocals Work
Defined zones for distance and near.
Bifocal lenses feature two distinct optical zones: the upper section provides clear distance vision while the lower segment is dedicated to near tasks like reading, writing, and detailed work.
Unlike progressives, there is no gradual transition between zones — each area provides its full corrective power immediately. Many long-time bifocal wearers prefer this clarity and simplicity.
- Immediate, full-power correction in each zone
- No adaptation period required
- Clear, wide reading segment
- Proven technology trusted by millions
