BifoLux R28
With more advanced technology than a conventional invisible bifocal, the BifoLux incorporates a very short progression to avoid aberration zones that disturb vision at the junction between distance vision and near vision.
Benefits:
- Wide near and distance vision without distortion
Target wearers:
Ideal for wearers who struggle to adapt to progressive lenses and want an invisible addition with no discomfort between the different vision zones.
A smooth transition from DV to NV
Introducing this short corridor means the wearer feels no visual discomfort when changing focus
