Are you working with your computer routinely either as an office employee or a game lover? Are your eyes dry, watery, blurry, seeing double or sensitive to light? If your answer is a "yes", you are likely one of many people today who suffer from digital eyestrain, also called computer-vision syndrome. What on earth is this syndrome coming from? What can we do to deal with this problem?
Eyestrain is often related to the amount of exposure to screens, the distance from eyes to screens and the use of multiple screens simultaneously. However, studies have also shown that the blue light produced by digital devices today reaches further into the eyes than other kinds of light. This light actually assists attention during the day but can result in interrupted sleep patterns at night.
Years of scientific researches indicate that eyestrain isn't necessarily an unavoidable problem for those who deal with computer work in the daily base. There are ways you can adopt which can overcome the problem considerably. To begin with, your computer screen should behigh-resolution(高分辨率), at least 50 centimeters wide diagonally and may require a screen filter to decrease reflections. Also, be aware that "computer glasses", which cut down glare and blue light，are available.
Besides, to reduce your risk for computer-vision syndrome, take frequent breaks during your computer workday. Many workers take only two 15-minute breaks from their computer throughout their day. According to a recent study, eyestrain are significantly reduced when computer workers take four additional five-minute "mini-breaks" throughout their workday. Finally, many of us fall into bad habits while using digital screens, which only worsen the effects of eyestrain. While viewing digital screens, many peopleblink(眨眼) one third less often than they usually do. Place a reminder on your computer to "blink" so that your eyes don't dry out.
