Are your eyes irritated, dry, watery, blurry, seeing double or sensitive to light, and do your back and neck ache? If so, you are likely one of many people today who suffer from digital eyestrain, also called computer-vision syndrome.
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.
Scientists have also said that eyestrain is not a necessary evil, even in a modern world that revolves around technology. Changing some simple details about your relative position to screens, such as staying about 60 centimeters away, will help. Also, avoid overhead and other direct sources of light, and use shaded lamps and window blinds while looking at digital devices instead.
Beyond the way that relates to digital screens, there are also ways to change how you view screens that are helpful in combating eyestrain. To begin with, your computer screen should be high-resolution(高清的), 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 and those contact lenses can increase the risk of eyestrain.
Besides, to reduce your risk for computer-vision syndrome and neck, back and shoulder pain, 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, discomfort and eyestrain are significantly reduced when computer workers take four additional five-minute “mini-breaks” throughout their workday. And these additional breaks don’t reduce the workers’ productivity.
Finally, many of us fall into bad habits while using digital screens that only worsen the effects of eyestrain. While viewing digital screens, many people blink one third less often than they usually do. Place a reminder on your computer to “blink” so that your eyes don’t dry out. Also, rest your eyes’ focusing muscles by using the 20-20-20 rule: Every 20 minutes, focus on something 20 feet away for 20 seconds.

Never have I experienced such a special time. It is three months since I begin to study at home. I’ve become accustomed to have classes online. Between classes, I can discuss which I don’t understand in class with my classmates. I can also turn my teachers for help at any time. I take exercise every day at home to stay health. My parents and I usually watch news over dinner to get the latest informations on the disease. We feel sorry for the people who are affected by them both at home or abroad. Leaves turn green and flowers become fragrantly in the school yard. I hope everything returns to the normal. And I’m expecting to go back to school soon.
