What is the 20-20-20 rule?

It is a common misconception that you can cause permanent damage to your eyes by frequently using display screen equipment (DSE), when actually there is no evidence to support this.

However, there are a number of risks associated with DSE work. In fact, in 2020 alone there were over 480,000 workers suffering from musculoskeletal disorders in Great Britain. It’s unclear how many of these are as a result of the incorrect use of DSE, however, it’s crucial that DSE users understand how to properly use their equipment and how often they should take breaks.

Another common issue surrounding the use of DSE is eye strains. There are many ways that a DSE user can strain their eyes, including by having improper lighting, screen glare, or even working on a screen for too long without any breaks.

One of the most commonly practiced methods for taking breaks from the use of DSE is the ‘20-20-20 rule’. This exercise for a DSE user's eyes requires that they look up from their screen at something roughly 20 feet away for 20 seconds, every 20 minutes.

As a result of frequently practicing this exercise, it gives the DSE user’s eyes a chance to relax and to prevent them from being strained.

Here’s a short snippet from our DSE Training course that explains the 20-20-20 rule...
