epik™ Office UltraHD
Simple Prescribing!
Office work and many other activities require sustained intermediate and near vision. Progressives do not provide a large enough viewing zone to support these activities comfortably. epik™ Office UltraHD lenses feature wider intermediate and reading zones.
epik™ Office UltraHD Lens Features
: Designed for wider intermediate and near, low astigmatism.
: Three intermediate focal lengths for simple prescribing.
: 14 to 35mm fitting heights.
: Optimized with Rx and Position of Wear compensation.
: Ordered and fit like a progressive lens.
epik™ Office UltraHD lenses do not offer a clear field of view beyond 16 feet. They should NEVER be used driving or for activities that require clear distance vision.

Prescribing
-
Provide progressive Rx and measurements
-
Choose desired intermediate focal length based on the wearer's requirements.
Fitting
-
Fit like a progressive lens.
-
Use monocular PD.
-
Minimum frame B dimension of 25mm.
-
14 to 35mm fitting heights.
Ordering
-
Order like a progressive, specify the intermediate focal length.
-
DO NOT MANIPULATE THE POWER.
UPGRADE to the ND4™ Series!
DRV - Digital Relaxed Vision
Digital eyestrain complaints are highest in the 18-40 age group. Most people hold mobile devices about 25% closer than printed materials, and symptoms of presbyopia are occurring at earlier ages.
Wide natural
distance zone
Almost unperceived peripheral astigmatism
Wide enhanced
near zone
: Enhanced single vision design with patented back-surface free-form technology.
: Choice of +0.50, +0.80, or +1.10 diopter power boost in the lower part of the lens.
: Allows eye muscles to relax for easier accommodation and reduced eyestrain.
: Ideal for wearers aged 18 to 40 who need extra near vision support.
: Individual free-form design with prescription optimization.
: Upgrade to the ND4™ Series pupil-optimized correction for enhanced clarity in all lighting.
