Use the 20-20-20 Rule for Screen Breaks
Follow the 20-20-20 Rule
Try this
During long periods of screen use, take a short visual break about every 20 minutes and look at something about 20 feet away for 20 seconds. Use the reminder as a simple screen-rest cue, not as a treatment or a substitute for eye care.
Check-in: Did I take regular screen breaks, and are eye strain, dryness, headaches, or blurred vision still bothering me enough that I should discuss them with an eye-care professional?

Long periods of computer or phone use can make your eyes feel tired. The National Eye Institute recommends a simple screen-break habit: every 20 minutes, look at something about 20 feet away for 20 seconds. Brali keeps the rule simple and does not add claims about guaranteed symptom reduction or vision improvement.
1. Use a simple 20-20-20 break
During a long screen session, look away from the screen about every 20 minutes. Focus on something roughly 20 feet away and keep your gaze there for about 20 seconds.
2. Give near focus a break
The point is to stop continuous close screen viewing for a moment. A window view or another clearly distant object works well. Keep the break simple; you do not need a special app or exercise routine.
3. Let yourself blink normally
Digital eye strain can include dry or irritated eyes, and screen use can be associated with reduced blinking. During the pause, relax your gaze and blink normally rather than adding a complicated breathing or blinking count.
4. Fit the reminder to real work
A reminder can help if you tend to forget breaks. If it arrives during a moment that should not be interrupted, take the break at the next safe natural pause instead of abandoning the habit entirely.
5. Know what the rule does not replace
The 20-20-20 rule is general eye-health guidance, not a diagnosis or treatment. If eye strain, dryness, headaches, blurred vision, or other vision changes keep bothering you, discuss them with an eye-care professional rather than relying on break reminders alone.
Questions to consider
What is the 20-20-20 rule?
The National Eye Institute recommends taking a break every 20 minutes during prolonged computer use and looking at something about 20 feet away for 20 seconds. It is a simple way to rest your eyes from continuous near screen viewing.
Does the rule prevent eye disease or fix vision problems?
No. Treat it as a screen-break habit, not a treatment or guarantee. Regular eye exams and appropriate professional care still matter, especially if symptoms or vision changes persist.
What if a reminder interrupts something important?
Use the rule as a practical cue rather than a punishment. Take the short break at the next safe natural pause, then return to the task. Do not use screen reminders while driving or during another safety-critical activity.
