Back Surface Aspheric Design
The
Centra Vue is a concentric, simultaneous-vision design that places near-vision
“add” power in the center of the lens, then seamlessly transitions to a
peripheral “minus” power zone for distance vision.
This design is optimal for prescriptions between -4.0
diopters and +4.0 diopters for distance, with up to 1.25 diopters of add, or
cylinder no greater than -1.50 diopters.
Base Curve: 6.50 mm to 8.44 mm
Distance: -20.0 D to +6.00 D
Add Power: +0.75 to +3.00 D
