Introducing
Slide2Array… 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”
Slide3OFFERS
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
Slide4Optically Optimized Rx Powers
Aspheric /
atoric
Provides sharp, clear images not distorted by elliptical errors found in conventional surfacingAllows the design to perform at its best, regardless of the power
Slide5Conventional Surfacing
Different powers result in different design performance.

Slide6Optical Optimization
Atoric/aspheric back surfaces to optimize optical performance across all powers.
Improved visual fields in ARRAY design.

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….
Slide9Array 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)
Slide10Why 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)
