20 20 20 Rule for Eyes 


Except for the brain, nowadays, the most used body organ is our Eyes. The big issue these days is Screen Time. We mostly spend our time looking at screens of TV, mobiles, laptops, computers, other digital devices rather you don’t belong to the IT industry. That means Screening is included in all professions so it’s not easy to avoid it.

That’s why there is no other option except “To Take Care of Eyes”.

So, here the 20-20-20 Rule is applied which is nothing but a kind of Eye Exercise.

Stay with us for learning more about this eye exercise, how to do it, and whether or not the study says it’s operational.

What is the 20-20-20 rule for eyes?




Fundamentally, after every 20 minutes spent at screening, we should attempt to look away at somewhat that is 20 feet away from you mostly give preference to outside greenery or environment for a total of 20 seconds.

Now the next questions are:

Why choose 20 feet away?

Being exactly 20 feet isn’t the key. But, a human can focus on something approx. 20 feet far away things. Consider looking out a window at an object that seems far away, like trees or some buildings.

Why 20 seconds?

It receipts about 20 seconds for human eyes to completely relax. You can a glass of water or a cup of green tea at that time.

What about prompting to do every 20 minutes?

We probably get engaged in our work when we are watching at screens. We can set a timed reminder to pop up after every 20 minutes. There are also free apps like Eye Care 20 20 20 that can help.

What are eye strain symptoms?

Having tired, burning, or itching eyes are the main symptoms of eye strain.

Other symptoms include: 

  • watery eyes
  • doubled vision
  • dry eyes
  • blurred vision
  • headaches
  • soreness in the neck, shoulders, or back
  • trouble concentrating
  • sensitivity to light
  • difficulty keeping eyes open


What does the research say?

The American Academy of Ophthalmology clarifies that watching at digital devices won’t automatically damage your eyesight. But it can be a root to strain and spiteful indications. Because of screening, the natural blinking of eyes gets automatically decreased and it leads to dry and tired eyes.

Eye strain caused by screens is called computer vision syndrome (CVS). Taking regular breaks to look at faraway objects during screen time significantly decreases eye strain symptoms. In other words, the 20-20-20 rule works.
