About this deal

Judging a distance of 20 feet can be difficult. But looking at an object more than 20 feet away works just as well. When in doubt, aim for a longer distance rather than a shorter one. Spending long periods looking at a screen can strain the eyes. Using the 20-20-20 rule can help to prevent this problem. For every 20 minutes a person looks at a screen, they should look at something 20 feet away for 20 seconds. Try your best to remember to follow the 20-20-20 rule. Set a timer to remind you to look away every 20 minutes at an object that is about 20 feet away for a full 20 seconds.

Sit farther away from your computer screen. A good rule is to be at least 25 inches, or roughly an arm’s length, away. While you’re at it, move the screen so you have to look slightly downward at the screen. If the seconds you are subtracting is greater than the top number, borrow 1 minute from the top minutes and add 60 to the top seconds. Then subtract.Adjust the screen’s contrast and brightness: Change settings so that the screen is just bright enough to read the text without straining. The right contrast may change depending on the presence of sunlight. If minutes has a decimal, keep the whole number as total minutes and convert the decimal to seconds
