Computer users favor near-variable focus lens

Beaverton, OR-Patients overwhelmingly prefer near variable focus (NVF) lenses over progressive lenses for computer use, according to a survey conducted by PRIO Corp., which develops and sells testing equipment and lenses for computer users.

The study fitted 40 current wearers of premium progressive lenses with NVF lenses. Participants spent at least 3 hours a day at the computer.

The study found 81% preferred NVF lenses, with 70% saying they "strongly" preferred them over progressive lenses. It found 84% experienced the lowest level of computer eyestrain, 86% reported the best clarity, and 89% said they had less head movement, all with NVF lenses.

"NVF lenses typically give computer users much wider intermediate vision than general-purpose PALs," said Jon Torrey, PRIO's president and chief executive officer.
