Harfang

Harfang is our flagship: a progressive whose geometry is optimized by an artificial-intelligence engine to bring peripheral aberrations down to a minimum. It takes the wearing position into account (pantoscopic tilt, vertex distance, wrap) and, with the near PD measurement, the wearer's reading behaviour. The result: the widest fields in the range and near-immediate adaptation.

Who it's for

Demanding presbyopes, strong or asymmetric prescriptions, patients who didn't tolerate another progressive.

What sets it apart

  • AI-optimized geometry — aberrations reduced to a minimum
  • Personalized to the wearing position and the frame
  • Variable 11 to 17 mm corridor, measured near PD
  • 90-day adaptation guarantee
