【題目】閱讀下面短文，從短文后的選項(xiàng)中選出能填入空白處的最佳選項(xiàng)補(bǔ)全短文。選項(xiàng)中有一處為多余選項(xiàng)。

Children can spend hours a day looking at computer screens and other digital devices(數(shù)碼設(shè)備). Some eye doctors say this leads to an increase in “computer vision syndrome(電腦視力綜合征).”

Nathan Bonilla-Warford is an optometrist(驗(yàn)光師) in Tampa, Florida. 【1】 “A lot more children come into the office either because their parents have noticed that they have headaches or red or watery eyes or discomfort, or because their nearsightedness appears to be increasing and they’re worried,” he says.

【2】 “Even if their eyes start to feel uncomfortable or they start to get a headache, they’re less likely to tell their parents, because they don’t want to have the game or the computer or whatever taken away,” he explains.

He says another part of the problem is that people blink(眨眼) less often when they use digital devices. He says, “A person who uses an electronic device blinks about one third as much as we normally do in everyday life. And so that can result in the front part of the eye drying and not staying protected like normal.”

Eye doctors offer suggestions like following the rule that is known as the 20/20/20. That means every twenty minutes you should look away twenty feet or more for at least twenty seconds from whatever device you’re using.

Other suggestions include putting more distance between you and the device and using good lighting. 【3】 Many experts say children should spend no more than two hours a day using digital devices — with no screen time for children under two.

【4】 Dr. David Hunter, from Children’s Hospital Boston, has not seen an increase in his practice. “While it is possible to develop fatigue(疲勞) looking at screens for a long period of time, there’s certainly no proof that it actually causes any damage to the eyes,” he says.

A.But not all eye doctors have noticed an increase in problems in children.

B.Many eye doctors believe that the problem is getting worse and worse among children.

C.Dr. Bonilla-Warford says part of the problem is that children may be more likely to pay no attention to early warning signs than adults.

D.Of course, another way is to spend less time looking at screens.

E.He has seen an increase in problems in children.
