Transcript Prestige II
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 Distance 2.5mm Standard Inset Conventional Back Surface Design Optimized Inset PRESTIGE II Example: SPH -0.00 CYL -2.00 AX 45 Front-side Progressive Lens PRESTIGE II Benefit: Improved Panoramic Vision 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.
