Eye Break Time
Plan restorative pauses that follow the optometrist-endorsed 20-20-20 rule. Enter your total screen session, how often you pause, and the length of each break to reveal how many minutes you will invest in eye recovery.
This calculator supports healthy screen habits but does not replace personalised guidance from your eye-care professional.
Examples
- 240-minute workday, pause every 20 minutes for 20 seconds ⇒ 4 minutes of eye rest
- 480-minute marathon study session, pause every 25 minutes for 30 seconds ⇒ 9.6 minutes of rest
FAQ
What is the 20-20-20 rule?
Optometrists recommend that every 20 minutes you look at something roughly 20 feet away for at least 20 seconds to reduce digital eye strain and dryness.
Can I customise the break interval?
Yes. If you are prone to headaches or work under harsh lighting, shorten the interval to 15 minutes. Longer gaps may be fine for casual browsing but can aggravate symptoms during intensive focus work.
Why does the calculator divide by 60?
The break duration is entered in seconds. Dividing by 60 converts those seconds to minutes so the total recovery time aligns with your screen session units.
What else should I do during a break?
Blink intentionally, roll your shoulders, hydrate, and adjust lighting or screen position. Brief physical movement improves circulation and complements ocular relief.
Additional Information
- Total break minutes = (screen minutes ÷ interval) × break seconds ÷ 60.
- If the session length is shorter than the interval, you still owe yourself one full 20-second break.
- Dry or irritated eyes benefit from additional lubricating drops; consult an eye-care professional for persistent symptoms.
- Pair regular pauses with ambient lighting and screen filters to reduce overall strain.
