New Patented Free-Form Technology Surpasses
All Others in Thinness and Design
Newly Patented 100% Back Surface Technology
(Patent # 7,341,344 March 8th 2008)
COB – Convex on Back
AVI – Automatic Variable Inset
AAC in Distance – Advanced Aspheric Compensation
MPAC – Multi-Polar Astigmatic Correction
Benefit: Improved Cosmetics
Vs. Other 100% Back Surface PALs
Flatter Base
Much Flatter Plus Rx – Up to 25%
Thinner Minus Rx – Up to10%
Vs. Conventional Pals
Basically Same On Minus
Reduced Lens Thickness
Plus lenses up to 25% flatter
Facilitated by advanced prism thinning
calculations
Greatly Improved cosmetic appearance
compared to regular back surface PALs
Benefit: Improved Intermediate & Reading Area
Prestige Original AVI Technology
#1
Based on Distance Rx
Hyperope – Greater Convergence
Myope – Less Convergence
Based on Specific PD
Customized Corridor & Add Placement
Future AVI Software Updates
#2 – Specific Reading Distance Measurement
Prestige II incorporates automatic variable inset design to achieve point
focus for near vision objects. This requires the inset of the reading zone
relative to the distance zone to be extremely precise.
Taking into account the patient’s PD and the lens power, SEIKO
calculates the design needed to give clear binocular vision at the
standard 35cm near vision distance.
Benefit: Improved Vision Throughout
Totally Clear Above 180° (Uncut Lens)
Widest Distance Field of Vision
Expanded Peripheral Vision
Measured Power for Reading and Distance
Improved Performance For Difficult Rx
Eye Rotation, Vertex Distance, & Tilt Factored
45% Wider

Listing’s Law
Control of Cylinder in All Meridians
Reduced Oblique Astigmatism
As Worn Position
Adjusted Viewing Angle
Eye to Lens Alignment All Directions
Listing's Law governs the three-dimensional orientation of the eye and its axes of
rotation. It states that, when the head is fixed, there is an eye position called primary
position, such that the eye assumes only those orientations that can be reached from
primary position by a single rotation about an axis in a plane called Listing's plane.
SEIKO’s NEW Free-Form Lens Technology benefits from multi-polar astigmatic correction.
This is calculated using SEIKO software taking into account eye rotation factors as identified
in Listing’s Law.
Distortion and oblique astigmatism in the peripheral areas of the lens force the wearer to
constantly move their head to maintain a clear image. Prestige II manages unwanted
cylinder in all meridians, creating a balanced progressive design that reduces the need for
head movements and increases wearer comfort.
