Add to this the muscle strain on your eyes and you have a recipe for fatigue and diminishing productivity. Working at a computer for long periods on projects switches your brain into a flow state that prevents your eyes from blinking and causes them to dry up. It also reminds your eyes to blink more often which tend to stall when staring at a screen. It works by taking your eyes away from the screen and refocusing them on a distant object helping them to adjust and stay alert. The 20-20-20 rule is the perfect method to keep your eyes fresh while working at the computer for long periods. Without regular breaks, your eyes will become sore and your productivity level decreases. When you stare at a computer screen – a stimulus at close proximity – the eyes also dry out and become uncomfortable and red. When you focus on visual stimuli for a long period the muscles in the eyes become strained leading to tiredness and screen fatigue. Jeffery Anshel not only brought the method into popular awareness, but he also continued to develop and fine-tune his work to make the 20-20-20 rule one of the first things doctors and optometrists recommend for eye fatigue. In some ways, the invention of the 20-20-20 rule was an inevitable consequence of optical science and the steady progress of digital technologies. Jeff Anshel has followed up with new editions containing the latest research. Jeffery Anshel popularised the 20-20-20 rule concept in his 1998 book titled Visual Ergonomics in the Workplace, a book that quickly became a comprehensive and popular textbook on the subject of everyday eye health. Things such as room lighting, proximity to the visual interest, font size, and equipment are all considerations in Vision Ergonomics.ĭr. Vision ergonomics is a field of study that considers the impact of environmental factors on visual wellbeing. The 20-20-20 rule was developed in the field of Vision Ergonomics and was popularised by the American optometrist Dr. Up to 20 minute visual countdown timer with handle The Time Timer PLUS 20 Minute packs all the features that have made Time Timer visual timers the first. As it happens, the optimal time for an eye break in 20 seconds. Firstly, it takes your eyes off the digital screen which contributes to dryness – digital screens reduce the blink rate of the eye by around two-thirds – secondly, it improves focus and reduces strain on the ocular muscles by refocusing the eye. In short, it means taking your eyes off the screen every 20 minutes and looking at something 20 feet away for 20 seconds. The 20-20-20 rule is a way to prevent eye strain by taking frequent breaks from screens. It’s easy to forget that these digital screens affect our attention and productivity they can also affect our wellbeing too. There is little evidence that the blue screens cause any long-term damage to the eyes, but in the short term they can cause “eye strain”. ![]() Today, we spend much of our time looking at digital screens in fact, screen time has increased from 2 to 4 hours per day for almost half of participants of a YouGov survey carried out during the pandemic.
