Screens are a vital part of life in the digital age. Whether we are using a laptop, having a meeting on the internet, or scrolling through our phone, we spend hours looking at a digital device. Technology can make life easier, but long periods of screen time can cause tired, dry, irritated, and uncomfortable eyes.
The 20-20-20 rule is a very simple method to give your eyes a much-needed break. This simple habit can help you take frequent breaks from screens throughout the day and can help alleviate discomfort caused by long hours spent in front of screens.
This rule can be beneficial for anyone, whether you are a student, a working professional, or a person who finds it enjoyable to spend time online.
What Is the 20-20-20 Rule?
The 20-20-20 rule is a simple eye-care guideline that aims to minimise the strain that digital screens can cause to the eyes.
Here’s the rule:
- Screen Break: Pause every 20 minutes.
- Focus 20 feet away: Focus on a faraway object.
- At least 20 seconds: Give your eyes a break before starting back on your work.
Focusing on the screen for long periods puts constant strain on your eyes to focus at a relatively short distance. When looking at a distant object, they get a chance to switch their focusing effort.
The 20-20-20 rule is not a cure for all eye issues, but it could help alleviate digital eye strain if used regularly.
Why Do Our Eyes Need Regular Breaks?
Your eyes are always active during the day, but screen-based activities may also put a strain on your visual system.
It is common to hold the same distance from a digital device when reading, typing, playing games, or browsing the web. Also, we may blink less often than normal, leading to dryness and irritation.
When these habits are not broken up with regular pauses, they can cause the following symptoms:
- Tired or heavy eyes
- Dryness, burning, or irritation
- Difficulty seeing clearly (especially after using screens for extended periods of time)
- Forehead or head pain/discomfort.
- Problems switching from close to far and far to close. Trouble focusing on close and distant tasks and vice versa.
These symptoms are typical of Digital Eye Strain (DES), Computer Vision Syndrome (CVS), or Strain of Digital Vision.
Regularly break away from the screen, optimize screen settings, and practice good viewing habits can help prevent discomfort during screen-heavy tasks.
How Does the 20-20-20 Rule Help?
The key value of the 20-20-20 rule is that it prompts you to take breaks from extended screen time.
Let’s see how this simple habit can benefit your daily eye comfort.
1. Gives Your Eyes a Focusing Break
Give your eyes a break from focusing for 10 minutes.
Your eyes adjust to focus at the distance of a nearby screen when you look at it. Focusing on more distant objects alters the focusing demand and offers a respite from prolonged near work.
2. Encourages More Frequent Blinking
Suggests that the user blinks more often. Instructs the user to blink more often.
Many people tend to blink less often when reading digital information. This can help to accelerate the rate of tear evaporation and lead to dry eye symptoms.
A screen break is a helpful nudge to blink naturally, fully, and thus keep the eye’s surface comfortable.
3. May Reduce Visual Fatigue
Spending extended time in front of a screen can lead to tired eyes. Sometimes, it is useful to take short regular breaks from visually complex tasks so as to make screen-based work more manageable.
4. Encourages Better Screen Habits
The idea of the rule is to make you more conscious of time spent on screens. This awareness can assist you with healthier habits over time, which include movement, blinking, and changing how you look at things.
How to Practise the 20-20-20 Rule Correctly
There is no special equipment or complicated steps to follow to do the rule. All you have to do is take breaks every now and then.
Step 1: Make a reminder. Set a phone alarm, computer notification, or screen break application to remind you every 20 minutes.
Step 2: FOCUS ON OTHERS. Identify an object about 20 feet away, such as a distant building, tree, or object across the room.
Step 3: Hold for 20 seconds. Do not look at a screen right away, but instead fixate on the faraway object.
Step 4: Blink naturally. During the break, blink gently and completely to help keep your eyes lubricated.
Step 5: Safely and comfortably return to work. Go back to the activity and do it again after 20 minutes.
If you are not able to look out or find something at a distance of 20 feet, just look towards the furthest comfortable distance possible.
Additional Tips to Keep Your Eyes Comfortable
The 20-20-20 rule can be a good guideline, but it’s best to follow it along with other healthy habits to make screen time more comfortable.
Maintain the Right Screen Distance
Place your computer screen at an arm’s length and slightly lower than eye level. This helps to establish a comfortable viewing position and decreases the need to look up at the screen.
Adjust Screen Brightness
The lightness or darkness of your display should not be extreme compared to the lightness or darkness of your surroundings. Set the brightness, text size, and contrast so that reading is easier, without squinting.
Remember to blink.
Try to take a deep breath when using digital devices and make an effort to blink completely. An eye-care professional can recommend which lubricating eye drops might be suitable for you if you often suffer from dry eyes.
Take Longer Breaks
The 20-20-20 rule should be used as short visual breaks, but not as a substitute for prolonged sitting breaks. Get up from your desk, stretch, walk around, and leave your desk periodically when possible.
Maintain a Healthy Sleep Routine
Use of too much screen time late in the day can disrupt sleep. Think of cutting back on devices before bedtime and establish a sleep routine to improve well-being.
For eligible individuals who wish to reduce their dependence on glasses or contact lenses, LASIK eye surgery may be an option worth discussing with an eye-care professional.
Conclusion
The 20-20-20 rule is a simple, practical habit to help ease discomfort from long hours of screen use. Even the craziest schedule can be broken up by simply looking at something 20 feet away for 20 seconds every 20 minutes.
This technique should be used along with regular blinking, proper screen placement, good lighting, and regular eye exams for a more complete eye care regimen.
Your eyes work a lot every day. A little break for them is a small investment in your daily comfort and your visual health. Start practising the 20-20-20 rule today and make healthier screen habits part of your daily routine.
