If you’ve ever looked at a computer screen for hours on end, you probably know what it feels like when your eyes are tired and your head is tense.
What you are likely experiencing is digital eye strain (劳损). It could also lead to dry eyes. But are screens criminals behind needing glasses? Not necessarily, according to Melanie Schmitt, an assistant professor at the University of Wisconsin.
There has been an increase in cases of nearsightedness, but scientists don’t know if screens do the damage. “Several other factors can cause the phenomenon of nearsightedness, one of which is too much time spent indoors. Looking at a screen for too long can cause eye strain, but it doesn’t have any long lasting consequences,” Schmitt says.
A recent study by researchers in Madrid did find that LED lights—those used in screens—contributed to retina (视网膜) damage in the eyes of rats. However, more research is necessary to determine if the same effect occurs in humans.
You’re sure to feel the consequence of not taking screen breaks throughout the day. In order not to have digital eye strain, eye doctors say that you’d best take a 20-second break to look at something 20 feet away every 20 minutes. It also works a little bit if you adjust your computer to remove a glare or use eye drops to keep your eyes wet.
“I always tell patients and parents that come in to see me the importance of getting children outside to play and be exposed in natural lighting,” Schmitt says. “This goes for adults, too. Going outside is an opportunity for the eyes to rest from near-work and look at distance instead.” 32. What will happen if you fix your eyes on a computer screen too long?
A. You’ll feel tired all over. B. You’ll have a bad headache.[:&&] C. You’ll suffer from eye damage. D. You’ll lose your eyesight temporarily. 33. In Schmitt’s opinion, which of the following can cause nearsightedness? A. Staying indoors too long. B. Using LED lights. C. Taking screen breaks. D. Using eye drops often. 34. What’s the best way to prevent digital eye strain?
A. To keep eyes wet all the time. B. To follow the 20/20/20 rule.
C. To avoid doing much near-work. D. To sit as far from the computer as possible. 35. What would be the best title for the text?

Happy to know your eagerness to improve your Mandarin, I will try my most to help you.
Recognized as one of the most difficult languages in the world, Mandarin learning takes time. As the saying goes, practice makes perfect. If you want to learn it well, you should spend much time practicing Mandarin every day, such as reading aloud or communicating with local people. Besides, you’d better read as many books as you could so that you can have a better understanding of Chinese culture, in which way your Mandarin will be greatly improved. Other alternatives including watching Chinese programs and singing Chinese songs are also good choices.
I’m sure that you will make great progress as long as you devoted yourself to learning the language and persist with your study. Wish you all the best!

69. thankful
70. to work
