These days, most people have been working from home, thus increasing the amount of screen time from spending hours staring at screens such as your computer, smartphones, televisions, and a lot more electronic devices with screens. One of the consequences of looking at screens for long periods is eye strain, but there might be something that could help reduce the chances, called the 20-20-20 rule.
What is the 20-20-20 rule? It is a strategy to lessen the chances of eye strain wherein after 20 minutes of looking at a screen, you look away towards something placed 20 feet away, for 20 seconds.
20 feet is very specific, how could you easily tell if that object is 20 feet away? Well, there is no telling really, unless you measure it but being exact is not the point. What it means is that you just need to look at something that is far from you, like a tree outside the window, or the building opposite from you. If you are working in a small space, try walking outside or somewhere away from your space just to rest your eyes.
Take care of your eyes with regular visits to your ophthalmologist Bellingham, WA.
