More than 90 percent of adults report using digital devices more than two
hours a day, putting them at risk for digital eye strain. Our options are limitless,
often including more than one device at a time from televisions, smartphones,
computers, tablets or e-readers and video game consoles. When face-to-face
with computers, screens sit about two feet from our eyes and people tend
to stare at them for prolonged periods, which decreases blinking. Blinking
is important to prevent dryness or irritation in eyes. In addition, many of
workspaces are not “eye-gonomically” designed to prevent digital eye strain.
For smaller digital devices, they tend to be held 8 to12 inches from the eyes,
even further fostering conditions for digital eye strain, which is characterized by
dry, irritated eyes; blurred vision; eye fatigue; and head, neck and back pain
