On average 3× larger zone of excellent clear vision across the entire lens.
Visual clarity simulations across a wide range of prescriptions show that, on average, ZEISS ClearView FSV Lenses provide a 3x larger zone of excellent vision clarity when compared to regular ZEISS aspherical (AS) FSV lenses.
This clear zone is up to 4.6x larger for higher myopic prescriptions and up to 5.1x larger for higher hyperope prescriptions. — ZEISS AS SV *FSV lens measurements shown SPH -3.00/CYL -2.00 ZEISS ClearView SV.
The zone of excellent vision clarity is defined as a continuous circular area of unblurred vision on the lens - below the threshold of just noticeable blur.
This means clear vision over a larger area of the lens for all single vision lens wearers, allowing greater comfort. SPH -3.00/CYL -0.00 ZEISS AS SV ZEISS ClearView SV.
