Gunnar glasses are designed for digital electronics users. In fact, the company calls its line of specs "digital precision eyewear." Now, let's go through the marketing hype and see just how much of it is accurate, based on my wearing my Gunnar specs for about a week and a half.
First off, Gunnar states that according to the Vision Council of America, 90 percent of people who use a computer for more than three hours a day suffer from eye strain. Gunnar Optiks lenses, with what the company dubbed iAMP technology, are said to reduce eye strain when the user is staring at the cold glare of a computer screen.
