HOYA Transmittance Control 3D Design Software: Array… is a PAL design HOYA Transmittance Control 3D Design Software: Models how human eyes truly see with each prescription Compensates for wearing position Modifies design for optimal intermediate and reading area placement Balances design symmetry for binocular vision and reduced “swim effect”

OFFERS Optimization and customization in every prescription Wider viewing area for both myopic and hyperopic patients Sharper, clearer, distortion-free viewing Superior vision at all distances Larger cut outs make clear and sun options easy to order

Optically Optimized Rx Powers Aspheric / atoric Provides sharp, clear images not distorted by elliptical errors found in conventional surfacing Allows the design to perform at its best, regardless of the power

Optical Optimization Atoric/aspheric back surfaces to optimize optical performance across all powers. Improved visual fields in ARRAY design.

Constant viewing angle As Worn Design The design is adapted from refraction environment to the real world wearing in a frame Wearing Position   Refracted Position Pantoscopic angle @ 8° No pantoscopic angle Frame wrap 0° No frame wrap Viewing angle up to 40° Constant viewing angle Vertex distance 14.5 mm Vertex distance 12 mm

4 Corridor Lengths: When the ECP Chooses ARRAY 11 mm, 13 mm, 15 mm, 17 mm Y71 22W HOYA defines corridor length as the distance in mm from Eye Point to 100% of add power Competitors define corridor length as the distance from eye point to 85% of add power….

Array design with four corridor profiles: • 11 mm for 14 mm minimum fitting height • 13 mm for 17 mm minimum fitting height • 15 mm for 20 mm minimum fitting height • 17 mm for 23 mm minimum fitting height (corridor lengths are measured from fitting point to 100% of add power)

Why you might want to specify corridor length Duplicate design between two or more pair of glasses, i.e. clear general purpose and sunwear. Converting a bifocal wearer to a progressive Power imbalance between right and left eyes where slab-off may be indicated (anisometropia)

Backside Free-Form Surfacing Technology Array… is also Backside Free-Form Surfacing Technology Entirely free-form surfaced on the backside of a single vision, semi-finished lens blank with a design and optically optimized Rx powers. Single vision, semi-finished lens blank; any material

Backside Benefits Wider fields of vision as compared to conventional PALs However…. Depth of product availability: materials, treatments, wraps

The Difference Between ARRAY and Integrated Double Surface Front Vertical Component Back Horizontal Component Aspheric Atoric Rx All progressive lenses, except HOYALUX iD series, place magnification on one side of the lens. Having magnification on only one side causes the primary issues patients have with progressive lenses: • Limited fields of vision, especially in the mid and near ranges • Uncomfortable transition between far and near vision • Swimming and swaying sensation, especially while moving While backside free-form processing provides substantially improved performance over conventional lenses, these issues are not entirely eliminated. Two Sides are Better than One All design and Rx components on back

Integrated Double Surface Technology Front surface, vertical component Shorter eye rotation Greater surface quality control Back surface, horizontal component Wider perceived zones Reduced peripheral distortion Greater surface quality control What are the benefits of the double surface design? The front surface contains only vertical components and the benefit is to shorten the rotation of the eyeball to go from the upper portion of the lens to the bottom – distance to near powers. Here is what that means; hold your finger up close to your nose and look from the top of your finger to the bottom near the knuckle. Kind of a long way for your eyes to travel, isn’t it? Now, put your finger about 6 inches away further from your face and do the same thing……….a lot easier, right? That’s the advantage of puuting the vertical component of the front surface….it is easier for the eye to travel from top to bottom. Now the back side is the horizontal component which is the “channel” and contains the peripheral distortion, you know, the blurry areas that show up on either side of the lenses. By putting this part on the back side it is sort of like looking through a keyhole. The closer you get to the keyhole the more you see on the other side. That is the advantage of putting just that part on the back side. So, integrated double surface provides the benefit of shorter eye rotation from top to bottom because only that part of the design is further way from the eye and the “keyhole” is closer to the eye and has a wider field of view.

Array design markings 4 mm drop; from Eye Point to Prism Reference Point There are 3 types of addition powers built into the Hoya Free-Form prescription engine. As Worn, Front and Back. The addition power can be ground to read in a lensometer from the front side and the engraving will be the letter “F” (which is the default). Conversely, the addition power can be ground to read in a lensometer from the back side and the engraving would be the letter “B”. If the option for AS Worn is utilized, the addition power will not read as ordered but slightly different depending upon the position of wear measures that were given and the “W” will appear in the temporal area where the 2 digit add power is engraved.

Ordering ARRAY; no selection of corridor ARRAY VL ARRAY VL in drop down menu (variable length). The computer picks the appropriate corridor length.

Ordering ARRAY with a specific corridor length Choose from these 4 options in the drop down menu. ARRAY 11 ARRAY 13 ARRAY 15 ARRAY 17

Ordering Array in Wrap Frames You may use Spectangle or any other method for measuring the frames pantoscopic angle and the frame’s face form wrap, especially when ordering popular “wrap” sunglass eyewear A pop-up menu will appear and here you can fill in Pantoscopic tilt and wrap angle.
