You’re wrapping up your work, close the laptop lid, and immediately your eyes become heavy – they burn, they water, they get blurry. The 20 20 20 rule eyes helps you give your eyes a reset after spending hours in front of the computer. In this article, we’ll describe the rule itself, what science stands behind it, and five eye-care tips.
Why Screens Tire Your Eyes
When looking at a screen, the muscles used for focusing remain focused on objects that are close by. Your blink rate is reduced; therefore, your tears evaporate. After many hours, this can cause digital eye strain. Some symptoms include burning eyes, headaches, and blurriness.
| Symptom | Likely Cause | Quick Fix |
| Burning or gritty eyes | Less blinking, dry tear film | Blink often, use lubricating drops |
| Headache by evening | Constant near focus | Take regular distance breaks |
| Blurred vision | Focusing fatigue or old glasses | Rest, then update your prescription |
How the 20 20 20 Rule Works
It is easy to keep in mind the 20 20 20 rule. Every 20 minutes, one needs to look at something that is 20 feet away for 20 seconds. As per screen break rule, the eyes shift their gaze from close-up objects to distant objects, thereby relaxing the focusing muscles of eyes and offering some natural blinks too, which helps prevent straining your 20 20 20 rule eyes.
So, Does 20 20 20 Work?
It is quite common to question whether does 20 20 20 work. A scientific paper published on PubMed was written based on studies conducted in India, which involved 432 individuals during the pandemic. Only 34 percent of individuals used the 20 20 20 rule, at times. People suffering from eye burn and headache were more prone to using it. Furthermore, the authors stated that there is no strong evidence for its existence.
But, will does 20 20 20 work for everyone? It assists the majority of individuals in reducing the strain, but it cannot treat dry eyes or an outdated prescription. The 20 20 20 rule eyes routine is best considered as the first step, not the solution to the problem.
5 Screen Habits That Actually Help
The first of these habits is the 20 20 20 rule in itself. Use the phone timer or download a reminder app. The compliance with the 20 20 20 rule eyes routine will keep your vision refreshed throughout the day.
The second one is adjusting the screen brightness. Adjust it to be equal to that of your surroundings. Regardless of using the 20 20 20 rule eyes formula, your eyes will continue straining due to improper lighting.
The third habit is maintaining adequate lighting for eye health in the room. Do not study in the dark or with sunlight glaring at you. It would be better to use indirect lighting on the sides.
The next habit is monitor location. Make sure that your monitor is located at an arm’s distance away from you, with the top of the monitor being slightly below your eye level.
The fifth habit is only a set of eye exercises for computer users working on screens. Quick routines like palming, slow blinking, and shifting focus can easily be done following the screen break rule. These beneficial eye exercises for computer users do not last long, usually taking around two minutes.
| Habit | How to Do It | Time Needed |
| 20-20-20 breaks | Look 20 feet away for 20 seconds | 20 seconds every 20 minutes |
| Adjust brightness | Match screen to room light | One-time setup |
| Better lighting | Use soft side light, cut glare | One-time setup |
| Screen position | Arm’s length, top at eye level | One-time setup |
| Eye exercises | Palming, blinking, focus shifts | 2 minutes, twice a day |
