Question

【題目】

Nowadays, many children spend many hours a day looking at computer screens or other digital products(數(shù)碼產(chǎn)品). Some eye care professionals (專業(yè)人士) say all the screen time has caused more children to have eye problems.

Nathan Warford is an optometrist ( 驗光師) in Florida, USA. He says he has seen an increase in problems in children.

“Some children come into the office because their parents have found that they have red eyes. Others come because their degree of short-sightedness is increasing very fast and their parents are worried,” he said.

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. These children are afraid that their parents would take their games or the computer away.

Another part of the problem is that people blink (眨眼睛) less often when they look at the screen. When a person uses a computer or other digital products, he or

she blinks about a third as much as we normally do in everyday life. If we blink less often, our eyes can't stay wet or are too tired and they will not be protected like

normal.
