You get serious eye strain if you constantly work on a computer, especially for long stretches at a time. To reduce the strain and your 20/20 vision, you can try the 20-20-20 method. That means look at something 20 feet away for 20 seconds, every 20 minutes. If this method doesn’t work for a few days, consult a certified eye specialist to find the potential cause behind your inaccurate vision, and get the proper treatment.
