The Telescopic Spectacles G 2 bioptics from ZEISS

The Telescopic Spectacles G 2 bioptics combine the benefits of corrective eyewear
with a telescope system, resulting in enhanced visual performance. The telescope optics with 2x magnification are cemented onto a plastic or glass carrier lens – individually for each wearer depending on his or her requirements. The optical system is positioned above the wearer’s line of vision to ensure that the spectacles can be used in the normal way for distance and/or near vision. When a distant object requires special attention, the user can look through the telescope system by moving his/her head or eyes to obtain a magnified image of the viewed object.

The benefit:

unlike a hand-held monocular telescope, the user does not need to hold the system, keeping hands free for other activities.

This makes the Telescopic Spectacles G 2 bioptics ideal for situations in which orientation to the surrounding field is important:

  • in traffic (e.g. recognizing street signs, house or bus numbers);
  • in hobby or leisure activities, e.g. watching TV, observing nature,
    going to the theater or cinema and attending cultural or sporting events;
  • for orientation when out shopping or walking along the street;
  • for early face recognition.

The Telescopic Spectacles G 2 bioptics are also suitable for use as a magnifying visual device by young users at school. Unlike a video magnifier, it offers the benefit of unlimited mobility and flexibility.
