Today, more than 83% of Americans report spending at least two hours a day in front of a computer, tablet or smart phone screen, and many frequently experience the uncomfortable and disruptive symptoms of computer vision syndrome (CVS): eyestrain, headaches, blurred vision, dry eyes and shoulder or neck pain. Until now, prescription eyeglass wearers concerned about blue light emissions had to either buy a separate pair of glasses for screen time or invest in a new pair of prescription glasses with expensive, blue light blocking lenses. With our durable FitOn DT frames, you don’t have to choose between your protection and your prescription – you can have both. Each pair of FitOn DT glasses is equipped with high-performance DigiTec lenses, which use “natural light” deposition lens technology to block blue light emissions and harmful UV radiation. The lenses’ anti-reflective coating cuts distracting glare and helps you see more clearly, extending screen time for hours. Plus, if you order directly from Eagle Eyes, your pair of FitOn DT lenses will arrive with a free microfiber soft cleaning case to help keep your advanced optical technology protected.EYE COMFORT: Designed to reduce glare and renew tired, overworked eyes.
