What is 3-Zone Progressive Design™?
3-Zone Progressive Design™ is a lens design for presbyopic lenses that was developed by Bausch & Lomb Inc.
It delivers vision correction for 3 different distances: near, intermediate, and distance.
3-Zone Progressive Design™ further explained
When presbyopic patients are asked about their visual needs in the workplace, they prioritize near and intermediate vision without compromising distance vision. This requires a lens design with near, intermediate, far distance vision and with a smooth, seamless transition in-between. The 3-Zone Progressive Design™ promises to meet those visual requirements by delivering clarity through consistency while providing patients with the comfort of MoistureSeal™ technology: a technology found in various Bausch + Lomb ULTRA lenses.
The progressive design is distinguished by large areas of consistent focusing power in the near, intermediate and distant zones. In other words: With the consistency of power, a patient's retina receives a properly focused image, one that remains consistent within each area of the near intermediate and distant zones.
Real-world patient experiences are always the ultimate test for any contact lens and according to their presbyopic patient evaluations, a dedicated wide area of consistent power within each zone provides the retina with a clear image at these key distances.
The 3-Zone Progressive Design™ was introduced in 2016 as part of the release of the new presbyopic ULTRA lenses.
