The 20-20-20 Rule To Prevent Eye Strain
Many of our jobs require us to constantly stare at a computer or phone screen for long periods of time, which can put a strain on our eyes. When we work at a computer, our eyes have to focus and refocus all the time, causing what is known as computer vision syndrome. There is a simple way to help relieve symptoms. Computer vision syndrome includes a whole range of eye strain and pain. Research shows that between 50% and 90% of people who work at a computer screen have at least some symptoms. This problem can also affect our children when they stare at tablet or phone screens for hours on end. Being surrounded by screens – from laptops to desktops to cell phones, TVs and tablets – our eyes are experiencing more screen time than any time in history, and it’s taking a toll.
The best way to treat this problem is by cutting the glare on our screens or simply take frequent breaks from the screen. Use the 20-20-20 rule. Designed to reduce eye fatigue, the 20-20-20 rule says that every 20 minutes of screen time, you should look away at something at least 20 feet away for at least 20 seconds. These regular screen breaks give your eyes some much-needed rest and help prevent eye strain.
We should also be sure to blink often to keep our eyes moist, and if they still feel dry try eye drops. Don't forget regular eye check-ups for you and your kids.
