[20-20-20 Rule] Keeping Digital Eye Strain Away with the Pomodoro Technique

Set a tomato timer for 25 minutes, focus, and then take a short break:

Your work and study can move forward dramatically.

The Pomodoro Technique

The final exams were being held at the university.

Everyone had stayed up all night studying, taking in a dangerous amount of caffeine, rubbing their eyes as they worked to memorize their class notes.

They reread the same passages, their minds in a muddle, remembering nothing:

“Overstudying” is pointless.

Francesco Cirillo realized this in his first year of university.

After each stretch of focus, he took 10 minutes to do nothing.

Because “pomodoro” is the Italian word for tomato,

it came to be called the “Pomodoro Technique”.

Today, the focus period is set at 25 minutes, and it is known around the world as a way to boost productivity.

and it was spread from an ergonomics perspective by Dr. Jack T. Dennerlein of Boston.

The Pomodoro Technique is almost the same as the “20-20-20 rule” 🍅

○ Work gets done
○ Study gets done
○  You can expect it to keep digital eye strain

away as well.

You could buy a tomato timer, but using an app is probably more practical.
