Optics
Balance Progressive Technology, two different optical designs, individualized for each wearer and eye by fitting a D lens or an N lens.
Stabilization
Optimized Toric Lens Geometry, a uniform horizontal thickness with a wide ballast band that orients the lens.
Material
Aquaform Technology, which retains water from core to surface without a surface coating or added wetting agents in the lens material.
Study
93% success on initial fitting using the fitting guide, in a subject masked, randomized, bilateral, cross-over evaluation of 27 wearers, astigmatic presbyopes at 2 sites in the UK and US.
