A study by eye care company Eyezen has shown that younger people are at a higher risk group of digital eye strain. According to the study results, 57 percent of the optometrists said teenagers were commonly referred to them as a result of frequent device use. Eye strain accompanies different symptoms like dry eyes, headache and neck pain. The study demonstrates that dry eyes and headaches were seen almost as often at 78 percent and 72 percent.

Another report "Eyes Overexposed: The Digital Device Dilemma" by the Vision Council reports nearly eight out of every 10 Americans who suffer from digital eye strain use two or more devices simultaneously. The report covering more than 10,000 adults, finds that 65 percent of Americans experience digital eye strain symptoms, such as dry, irritated eyes, blurred vision, eye fatigue, neck and back pain and headaches. Findings of the report show that one in 10 people spend at least three-fourths of their waking hours on a digital device, and that prolonged periods of use appear to exacerbate symptoms as 96 percent of Americans who experience digital eye strain spend two or more hours each day using devices.

Digital eye strain is the physical discomfort that occus two or more hours in front of a digital screen and is associated with close to mid-range distance of digital screens, including desktop and laptop computers, tablets and smartphones.
