Understanding the Technology Behind Unity Via II

As of October 11, Unity® Via II is now the best and only option for Unity Progressive Lenses.

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[1]: 

EquiBalance Technology

• Equalizes add power for both eyes when scanning across a wide region of visual space
• Better correspondence of binocular images
• The result: more comfortable binocular vision

​
OptiScreen Technology

• Expands near and intermediate areas (horizontally and vertically)
• Enables more natural vision when using digital displays
• The result: easier viewing of digital displays of all types and configuration no matter where they are located

 
InnoVue Technology

• Optimizes vision correction at every point in the lens
• Significantly reduces lateral blur and distortion
• The result: clearer peripheral vision and faster adaptation

With Unity Via II, we’ve achieved a significant advancement in progressive lens design to meet today’s demanding visual needs.
