As of October 11, Unity® Via II is now the best and only option for Unity Progressive Lenses.
One of the most persistent challenges of progressive lenses has been the inherent astigmatism aberrations, which are intrinsic features in the lenses’ surface. A progressive lens always has astigmatism aberration in the periphery, which is perceived by the wearer as blurriness; it also distorts shapes so that straight lines appear twisted or curved. The latter effect may disrupt depth perception, causing a swimming sensation.
Expanding the View, Personally
Although astigmatism aberration cannot be entirely eliminated, it can be reduced to some extent. When Unity Via progressives were first introduced, peripheral astigmatism was decreased to very low levels compared to other progressive lenses on the market. The astigmatism was directed radially away from the lens’ center to where it could do the least harm. This approach is still being used in new Unity Via® II lenses.
InnoVue technology is our latest advancement in lens design, one that significantly reduces the area of objectionable astigmatism. A combination of improved mathematics and software used in Unity Via Plus II and Unity Via Elite II lenses achieves even lower levels of astigmatism, reducing wearer’s sensation of blur and swim. This is possible due to the individual optimization available in these lenses, which takes into account the frame shape, fitting height, and wearer’s individual pupillary distance.
InnoVue allows a truly personalized approach to progressive lens design, taking into consideration a patient’s unique attributes—and even the frame shape—to create the best visual experience possible.
