In designing progressive lenses, it’s important to provide vision correction that simulates the way each eye naturally focuses so that we can enjoy all the benefits of natural binocular vision. In the past, progressive technologies emphasized correct focus for a range of distances only when viewing objects located on the visual midline. EquiBalance Technology expands this capability laterally across the visual field.
Expanding Beyond the Midline
Unity Via II lenses were developed using a new design tool that optimizes the lens by providing much greater control over the surface. EquiBalance Technology resolves the inherent imbalance of dioptric powers down the length of the progression, restoring the equality of addition power and astigmatism on the left and right side of the corridor. This equalizes the amount of focus provided by the lenses and the amount of blur perceived by each eye to produce more natural binocular vision, especially in the intermediate and near vision areas. The result: significantly improved wearer comfort with reduced eyestrain.
Our EquiBalance Technology is truly a game changer, expanding a progressive wearer’s visual field laterally for more comfortable viewing at all distances.
In our next post, we’ll explore OptiScreen Technology and the benefits it provides for patients living in an increasingly digital world.
