When making recommendations, the doctor will take a person’s occupation and overall eye health into account. The 20-20-20 rule involves taking a 20-second break from looking at a screen every 20 minutes. During the break, a person focuses on an object that is at least 20 feet away, which relaxes the eye muscles. The 20-20-20 rule is a popular way to reduce eye strain caused by looking at digital screens for long periods. The units involved in this conversion are seconds and minutes.

Twenty days later, self-reports showed no change in computer eye strain symptoms. But results of a clinical test, “tear break-up time,” indicated a significant reduction in dry eye. An alternative is also that one minute is approximately three times twenty seconds.
