Seiko’s PCWide lens was created for people who spend most of their day in front of a computer or use a digital device.
If you use a computer, tablet, smartphone, or other digital device, you’re like most Americans who, with the rest of the world, have become increasingly dependent on them. While this technology provides some great capabilities, it also presents some unique challenges to both single vision and presbyopic patients. That’s where Seiko Optical Products of America, Inc.’s new PCWide free-form occupational progressive lenses come in.

The new PCWide eliminates the need for the wearer to constantly remove his glasses or adjust his head position when switching between computer and desktop work. Designed and processed using free-form technology, PCWide was created for individuals who spend most of their work time in a desktop environment.

Using a back-surface design, PCWide can benefit both single vision and progressive wearers. A single vision wearer can experience eye fatigue as she accommodates different focusing lengths. She also needs to constantly adjust head position when switching between reading and using a computer if she wears reading glasses.

Seiko’s PCWide lens uses a soft design and technology to control the lens in a precise way.

Presbyopes need help focusing at near and intermediate distances. While most current progressive lenses have a large distance area, wearers often find desktop work to be challenging because the intermediate area is too narrow for computer screens. PCWide eliminates this problem by providing spacious near and intermediate zones that don’t encroach on clear vision.

SEIKO PCWide lenses use a soft design and what the company calls Reverse Power Accommodation Technology to manage the lens power in a very precise and comfortable way. Reverse Power Accommodation Technology controls the linear reversal in power as the eye moves upward in the lens. In the reading zone, the lens has full reading power and decreases its plus power as the eye moves higher into the lens, stabilizing as an intermediate power.

Seiko offers three reverse power options: -1.00D, -1.50D, and -2.00D. The reading area is maximized at 10mm below the lens fitting point, which provides sharp focus at a reading distance of 35cm (14 in.). The lens reverses power through a 25mm intermediate corridor. Lens power at the fitting point is reduced by 40%, which provides sharp focus at the 50cm (20 in.) computer monitor distance.

When prescribing PCWide lenses, specify the single vision reading power and the monocular near pupillary distance. Select the lens type using Seiko’s Universal Selection Chart. If you wish to order based on specific reading and distance measurements, a software tool is available for download from Seiko’s Web site.

PCWide lenses come in 1.50, Trivex®, polycarbonate, 1.60, 1.67, and 1.74 materials. A Transitions® option is also available in all materials except 1.74, and an anti-reflective treatment is recommended to optimize lens performance by reducing reflected glare.
As Americans increasingly use their computers, tablets, smartphones, or other digital devices, more of them are going to need relief from the eye fatigue and focusing problems they encounter. That’s your cue to suggest Seiko PCWide lenses.
