GT2 by ZEISS is the all-time best selling semi-finished ZEISS progressive lens in North America, and winner of the Optical Laboratory Association’s Award of Excellence in the “Best in Lens Design” category. Why? Outstanding optics and more comfortable visual ergonomics, which combine to create a higher level of patient satisfaction.
ZEISS Optical Optimization and Management (ZOOM) Technology controls the design point-by-point across the lens to minimize the high- and low-order aberrations created by the changing curvature of the lens. This reduces aberrations to their mathematical limits, for clearer viewing zones, smoother transitions, and easier adaptation.
The visual behavior patterns of over 14,000 presbyopes were evaluated to determine the physiologically optimum position for the near and intermediate viewing zones. This allows more natural eye movement and greater comfort for near and mid-range tasks.

GT2 Short by ZEISS is designed for smaller frames with fitting heights as low as 13mm. Unlike many short-corridor progressive lenses, GT2 Short features uncompromised distance and reading vision at all fitting heights. The unique progressive geometry delivers continually widening near zone vision as the frame size increases, while maintaining an uninterrupted distance zone.
