ZEISS Trifocal Classic S728

Closing the Vision Gap for Intermediate Distances.

The trifocal lens ZEISS Trifocal Classic S728 1.5 provide the wearer with excellent vision not only for near and far, but also for intermediate distances from approx. 45 cm to 80 cm.

In principle, trifocal lenses are constructed and manufactured in the same way as bifocal lenses. However, they consist not only of a main lens and a segment, but also of an additional intermediate portion. The addition in this intermediate portion is approximately half that of the near portion.

Alternatives for Trifocal Lenses

To an even greater extent than bifocals, trifocals have now been almost completely replaced by progressive lenses. Progressive spectacles provide comfortable vision at all distances, as the dioptric power increases continuously from the distance to the near zones, providing optimum vision for every range without any annoying image jumps.

Benefits for the wearer

  • Excellent visual quality not only for far and near, but also for intermediate distances from approx. 45 cm to 80 cm
  • Large field of near vision
  • Segment fusing or molding on front surface and inner toric surface design ensure outstanding optical quality
