Many of us stare at computer, tablet, or phone screens for seven or more hours a day. We thereby risk developing computer vision syndrome (CVS), the digital eye strain related to blue light exposure. The National Institute for Occupational Safety and Health says that CVS affects about 90% of regular, daily users of digital devices.
Some simple steps may help to lower the risk of CVS, even when we cannot reduce the hours we spend online or at the keyboard. The first is abiding by the American Academy of Optometry’s 20-20 rule: for every 20 minutes you spend looking at a screen, spend 20 seconds looking at something far away. Drugstore reading glasses can provide a little relief for the farsighted who must frequently squint at screens, and getting contacts with a yellow tint or eyeglasses with lenses that block blue light can provide some relief as well. Diet can also play a role. Orange peppers and corn provide the body with sizable amounts of zeaxanthin, shown to decrease eye irritation. Spinach, broccoli, kale, and other leafy green vegetables contain lots of zeaxanthin as well as lutein, another nutrient good for the eyes. Even taking daily supplements of lutein and zeaxanthin may help the body to ward off CVS.1
