Eyesight plays a very important role in our daily life. Every waking moment, the eyes are working to see the world around us. Over forty percent of Americans worry about losing eyesight, but it’ s easy to include steps into our daily life to ensure healthy eyes. Here are five suggestions for a lifetime of healthy eyesight:
Schedule yearly exams.【B1】______ Experts advise parents to bring babies 6 to 12 months of age to the doctor for a careful check. The good news is that millions of children now can have yearly eye exams and following treatment, including eyeglasses.
Protect against UV rays (紫外线). Long-term stay in the sun creates risk to your eyes. No matter what the season is, it’s extremely important to wear sunglasses.【B2】______
Give your eyes a break. Two-thirds of Americans spend up to seven hours a day using computers or other digital products.【B3】______ Experts recommend that people practice the 20/20/20 rule: every 20 minutes, take a 20-second break and look at something 20 feet away.
【B4】______ As part of a healthy diet, eat more fruits and vegetables each day. Vitamins ( 维生素) C and E help protect eyesight and promote eye health.
Practice safe wear and care of contact lenses (隐形眼镜). Many Americans use contact lenses to improve their eyesight. While some follow the medical guidance for wearing contact lenses, many are breaking the rules and putting their eyesight at risk.【B5】______ Otherwise, you may have problems such as red eyes, pain in the eyes, or a more serious condition.

【B3】
选项
答案
G
解析
空格前一句说“三分之二的美国人每天使用电脑或其他电子设备的时间高达七个小时。”由此可推知空格处应该是说明这些行为的危害性。故G选项“这种频繁的眼部活动会提高眼睛疲劳的风险。”为最佳选项。
