Nowadays, many children spend hours a day looking at computer screens or other digital (數(shù)碼的) products. Some eye care doctors say all the screen time has caused more children to have what they call computer vision syndrome (視力綜合癥).

Nathan Warford is an optometrist in the US. He says he has seen more children having eye problems. “More children come into my office because their parents have noticed that they have headaches (頭疼)or red eyes, or because their degree of short-sightedness appears to be increasing (增加)very fast and they’re worried,” he said.

Dr. Warford says part of the problem is that even if their eyes start to feel uncomfortable or they start to get a headache, some children don’t tell their parents, because they don’t want their games or the computer to be taken away. Another part of the problem is that people blink (眨眼睛) less often when they look at the screen.A person who uses a computer or a digital product blinks about a third as much as we normally(正常地) do in everyday life. If eyes can’t stay wet or are too tired, they will not be protected like normal.

1.Why don’t some children tell their parents when their eyes start to feel uncomfortable?

A.They think it is not serious.

B.They don’t want their parents to worry.

C.They want to go to the hospital themselves

D.They want to continue playing computer games.

2.People normally blink about 20 times a minute.How many times do they blink if they use a computer?

A.About 4 times B.About 7 times C.About 11 times D.About 15 times

3.From the passage, we can learn that________ .

A.blinking is good for eyes

B.sleeping late is bad for eyes

C.children should blink as much as possible

D.we shouldn’t look at screens in a dark room

4.What is the passage mainly about?

A.Some ways of protecting children’s eyes.

B.Some information about the latest digital products.

C.Dr. Warford’s experience of working out eye problems.

D.Eye problems in children caused by using digital products.
