Frame, Lens and Wearer Perfectly Synchronized
 
Variable Corridor. Consistent Excellence.
Conventional progressives limit wearers to two basic corridor lengths: standard and short. These two design types are unable to provide optimal vision in all shapes and sizes of frame. As a result, many wearers experience truncated reading areas or distorted viewing zones. The Zeiss GT2 3DV continuously variable corridor expands or contracts the entire progressive design to make the best optical use of the lens surface area within the frame.

The result is wide, balanced fields of vision customized for each specific frame. Step up to true lens customization today. Your patients will enjoy virtually unlimited frame choices. And you'll never again have to worry about matching the lens design to the fitting height of the frame.
 
  Natural Binocular Vision.
40% Wider Fields of View.
Fully Customized for Every Rx. Zeiss GT2 3DV lenses are custom-designed for each patient’s unique combination of sphere, cylinder, axis, add and prism. By eliminating the base curve effect of conventional lenses, Zeiss GT2 3DV delivers superior clarity with up to 40% wider fields of view*.

Eliminates Base Curve Effect. Conventional progressives are confined to a limited range of base curves, which deliver the best optics for one and only one prescription. Other prescriptions, including the 70% of patients with astigmatism, will suffer some level of residual power error or blur. Zeiss GT2 3DV is optimized for every Rx, without compromise.

True 3D Optics. Zeiss GT2 3DV lenses optimize the complex interaction between the patient’s two eyes and their visual surroundings. The eye paths in both lenses are perfectly aligned, and prismatic imbalances virtually eliminated. The result is improved depth perception and binocular fusion.
 
Precise-FormTM Technology - 100% Back-Surface Optics. Zeiss GT2 3DV lenses are custom-engineered using Precise-Form technology by ZEISS. By combining patented technology and dynamic polishing control with meticulous process engineering, all the design optics are applied with submicron accuracy to the backsurface of the lens, closer to the eye. Unparalleled precision. Only from ZEISS.
