Tip of the week: How to save your eyes from screen fatigue

Take more eye naps. People blink two thirds less often when they’re looking at computer or other display screens, causing dryness and irritation. To keep eyes moist, “use the 20-20-20 rule”: Develop a habit of looking at something at least 20 feet away for at least 20 seconds every 20 minutes.

Try a different font. Check your computer’s default font. Fonts like Times New Roman that adorn letters with small tails, or serifs, can strain eyes by slowing word recognition. Sans-serif fonts that provide ample space between letters—such as Arial or Verdana—can be easier on the eyes.

Keep screens clean. Your eyes have to cross inward every time you focus on an image close to you. Since fingerprint smudges and dust make the focusing more difficult, wipe your screen once daily with a microfiber cloth.
