New Delhi: The 20-20-20 rule is a popular way to reduce eye strain caused by looking at digital screens for long periods. If you find yourself gazing at screens all day, your eye doctor may have mentioned this rule to you. Basically, every 20 minutes spent using a screen, you should try to look away at something that is 20 feet away from you for a total of 20 seconds.
How To Prevent Eye Strain?
Follow the 20-20-20 rule: Take as many breaks as possible to look away from the screen by using the 20-20-20 rule, which means that every 20 minutes you should focus on an object 20 feet away for at least 20 seconds.
Keep the screen at a distance: Experts say that the screen should be placed at least 25 inches or an arm’s length away from the face to put a lesser strain on your eyes.
Ensure proper lighting: It is very important to have proper lighting in the room and screen positioning should be done in a manner that there is no glare.
Adjust the display: Make sure to adjust the display settings to change the brightness of the screen so that less amount of blue light emits from the screen. Increase the font of the text as well.
Wear contacts: Always wear anti-glare eyeglasses or contact lenses to make sure that there is no unnecessary pressure on the eyes.
