epik™ DRV enhanced single vision performance.
The highest percentage of digital eyestrain complaints are in the 18-34 age group. Since most people hold mobile devices about 25% closer than printed materials, symptoms of presbyopia may occur in their early 30s, or even younger. The lower contrast and resolution of digital screens can also increase strain.
: Enhanced single vision design with patented back-surface free form technology.
: Choice of +0.50 or +0.75 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 25 to 40 years who need extra near vision support.
: Individual free form design with prescription optimization.
: Order like a progressive, use patient’s usual distance prescription.
Prescribing & Fitting
: Determine the distance Rx.
: Fit like a progressive lens (fit cross over pupil center).
: Use monocular interpupillary measurements for distance vision.
: Ensure a minimum frame B dimension (depth) of 25 mm.
: Provide fitting heights.
Most people hold mobile devices about 25% closer to the eye than printed pages, creating accommodation problems at a younger age.
Wide Natural Distance Zone
Allows for wide horizontal eye scans without muscle strain or peripheral blur (use patient's usual distance prescription).
Wide Enhanced Near Zone
Enhanced by either a +0.50 or +0.75 diopter increase in plus power to the wearer's usual distance prescription, allowing the eye muscles to relax and accommodation to be more easily maintained.
Almost unperceived peripheral astigmatism.
