The statistics are revealing. About 30 percent of adults now spend more than half of their waking hours on a digital device. And 83 percent of children between ages 10 and 17 use digital devices for more than 3 hours a day. An estimated 73 percent of 9- and 10-yearolds, and 80 percent of 13- and 14-yearolds now suffer from technology-induced sleep disorders. More children than ever are becoming nearsighted. The most alarming statistic is that 70 percent of Americans currently experience some form of digital eye strain, according to the Vision Council.
People aren’t going to stop looking at computers, so the solution is to make these devices easier on your eyes. “Eye doctors have long recommended taking frequent breaks, adjusting work stations to be ergonomically correct, and using proper eyewear. Many dedicated videogame players have long praised computer eyewear such as Gunnar Optiks’ which is backed by two clinical trials. Now the rest of us are discovering the importance of wearing high-tech eyewear developed specifically for computer and other digital device users. How much of the blue light spectrum do the lenses filter? “The lenses should filter the spectrum below 450 nanometers of blue light. If they don’t filter the right blue light frequency, they won’t prevent digital eye strain. Also, some lenses filter only about 10 percent of the blue light. Others filter as much as 65 percent. The best assurance that you’re getting the right type of blue light filter is to choose eyewear made with a computer-specific color formulation that is integrated directly into the lens material, and not applied as a surface treatment. These are considered medical devices.”
Is there an anti-reflective (AR) coating? “People don’t realize that when you look at a computer, your blink rate reduces to about one third. Your eyes get dry. Computer eyewear with a wraparound design that fits close to the face minimizes dry eyes by holding more humidity between the lens and your eyes. This is often one of the first benefits people notice.”
