Follow The 20-20-20 Rule
If you look at screens often, you may want to follow the 20-20-20 rule. On average, people usually blink 15 times per minute. But this amount decreases by 66% while looking at a screen, says the University of Iowa. By taking “blinking breaks,” you rest your eyes enough to prevent eye strain.
While looking at a computer or TV, follow the 20-20-20 rule. Every 20 minutes, stare at an object 20 feet away for 20 seconds. Twenty seconds is long enough for your eyes to rest fully. While looking away, make sure that you blink a few times.
