Understanding the Technology Behind Unity Via II
Today’s progressive lenses have evolved to feature a myriad of technologies designed to provide presbyopic patients with high performance and value. However, many wearers have continued to experience issues—limited viewing, eyestrain, and physical discomfort—especially with the visual challenges of a digital world.
A newly enhanced Unity® Via II portfolio has been developed to help address these issues, with the aim of delivering the best vision experience possible in a progressive lens. Unity Via II Progressive Lenses build upon the success of Unity Via designs to further enhance proven performance that ECPs have come to trust to consistently deliver high patient satisfaction.
Mathematical Innovation, Visual Revelation
Unity Via II progressives are the result of expanded mathematical capabilities in the Unity Via lens design software. It’s now possible to control the complete distribution of dioptric powers in Unity Via II lenses, not just in the central regions of a lens. These capabilities allow addition power and the resulting aberrations to be pushed around in ways that can satisfy multiple requirements: binocular correspondence, extended near and intermediate fields, and reduced areas of peripheral aberrations.
Three new technologies create this improved functionality in the lens:
With Unity Via II, we’ve achieved a significant advancement in progressive lens design to meet today’s demanding visual needs.
In our next post, we’ll take a deep dive into EquiBalance Technology and explore just how it works its magic to produce more comfortable, natural binocular vision for patients.
