First, follow the “20-20-20” rule. The American Optometric Association defines this rule as taking a 20-second break every 20 minutes to look at something 20 feet in the distance. This will allow your eyes to blink and relax. There are many apps available to help remind you to follow this rule.
Second, use lubricating eye drops before extended computer use. This tactic will reinforce the body’s natural tears and keep the eye’s surface hydrated. But avoid those “get-the-red-out” drops. They contain drugs that cause long-term redness and preservatives that may damage the outer layers of the eye. I have found that artificial tears labeled “preservative free” often work best.
