ZEISS FOR EYE CARE PROFESSIONALS

ZEISS Multifocal Lenses

Classical Product Solutions for Presbyopes

Bifocal/ Trifocal lenses provide presbyopes with clear vision for two or three different ranges, usually for distance, intermediate and near vision.
With a segment in the lower area of the lens, a bifocal or trifocal features two or three different powers providing clear vision in these distinct zones for near, intermediate, and distance.

Multifocal vs. Progressive Lenses

How do they differ?

Progressive lenses allow a seamless transition between near, intermediate and distance zones without noticeable lines of distinction. With bifocal or trifocal lenses, it is necessary that there be a distinct line separating the different powers allowing one zone of focus at any given time.

ZEISS Bifocal Classic Aphal R 22

ZEISS Bifocal Classic Aphal R 22 1.5 is a plastic, aspheric and lenticular bifocal which has been specially designed for aphakia and high hyperopic powers.
ZEISS Trifocal Classic S728

ZEISS Trifocal Classic S7x28 provide the wearer with excellent vision not only for near and far, but also for intermediate distances from approx. 45 cm to 80 cm.

The Slim Solution for High Plus Powers

ZEISS Bifocal Classic Aphal R 22

The special feature of ZEISS Bifocal Classic Aphal R 22 1.5 is its aspherically designed front surface and margin asphere. Instead of an abrupt transition between the aperture and the margin, Classic Aphal features a curved, continuous transition zone, preventing a sudden change in dioptric power and hence eliminating the ring-shaped gap in the visual field ("ring scotoma") typical of standard lenticular lenses. ZEISS Bifocal Classic Aphal R 22 1.5 therefore allows the wearer to utilise the entire visual field without any impairment of orientation.

Closing the Vision Gap for Intermediate Distances

ZEISS Trifocal Classic S728

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.
