Survey: Computer users laud near variable focus lenses

Near-variable focus (NVF) lenses for computer use are overwhelmingly favored over progressive lenses, according to a comparison survey conducted in four regions of the United States.

Near-variable focus (NVF) lenses for computer use are overwhelmingly favored over progressive lenses, according to a comparison survey conducted in four regions of the United States.

The survey, conducted by PRIO Corp., included current wearers of premium progressive lenses who spend a minimum of 3 hours daily at a computer and fitted them with NVF lenses.

The following results were reported:

  • 81% preferred NVF lenses.

  • 19% preferred progressive addition lenses (PALs).

  • 84% experienced the lowest level of computer eyestrain with the NVF glasses.

  • 86% reported the best clarity with NVF lenses.

  • 89% said they had less head movement with NVF lenses.

PRIO collected and analyzed the results of three surveys given to 40 computer-using subjects.

"We chose to conduct the survey because of the perception by many eye-care professionals and consumers that progressive lenses are a good choice for viewing a computer screen," said Jon Torrey, PRIO president and chief executive officer, in a company statement. "The data reported by subjects in this survey showed that NVF lenses are a much better choice in terms of comfort and clarity."
