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.31Experts 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 (紫外線(xiàn)). Long-term stay in the sun creates risk to your eyes. No matter what the season is, it' s extremely important to wear sunglasses.32Give your eyes a break. Two-thirds of Americans spend up to seven hours a day using com- puters or other digital products.33Experts recommend that people practice the 20/20/20rule: every 20 minutes, take a 20-second break and look at something 20 feet away.34As part of a healthy diet, eat more fruits and vegetables each day. Vitamins ( 維生素) C and E help protect eyesight and promote eye health.
Practice safe wear and care of contact lenses (隱形眼鏡). Many Americans use contact lenses to improve their eyesight. While some follow the medical guidance for wearing contact len- ses, many are breaking the rules and putting their eyesight at risk.35Otherwise, you may have problems such as red eyes, pain in the eyes, or a more serious condition.
答案與解析：
視力在我們每天的生活中扮演著(zhù)重要角色。只要醒著(zhù)，眼睛就在看周?chē)氖澜�。超過(guò)百分之四十的美國人擔心視力下降，不過(guò)，每天做到簡(jiǎn)單的幾步就能保證我們擁有健康的眼睛。以下的幾條建議能幫助你一輩子維持健康的視力：
·每年定期檢查。對眼睛的保護應該從小開(kāi)始。專(zhuān)家們建議父母在孩子6到l2個(gè)月大的時(shí)候。帶他們到醫生那里做一次詳細的檢查。好消息是，幾百萬(wàn)的兒童現在能夠每年接受眼睛檢查及相應的治療，包括佩戴眼鏡在內。
·保護眼睛不受紫外線(xiàn)的傷害。長(cháng)期處于陽(yáng)光下可能會(huì )對你的眼睛帶來(lái)危害。不管你這么做是出于什么原因，一定要戴太陽(yáng)鏡。太陽(yáng)鏡能適當地保護你的眼睛。
·讓你的眼睛休息一下。三分之二的美國人每天使用電腦或其他電子設備的時(shí)間高達七個(gè)小時(shí)。這樣頻繁的眼部活動(dòng)會(huì )導致眼疲勞的風(fēng)險增大。專(zhuān)家們建議人們采取20/20/20的法則，即每20分鐘休息20秒，看看20英尺之外的事物。
·多吃綠色蔬菜。這是健康飲食的一部分，每天多吃些水果和蔬菜：
維生素C和維生素E能保護視力，促進(jìn)眼部健康：
·安全佩戴和護理你的隱形眼鏡。許多美國人佩戴隱形眼鏡來(lái)矯正視力。盡管一些人在佩戴的時(shí)候會(huì )遵從相應的醫療建議，許多人卻不顧規則.從而危害到了他們的視力。一定要聽(tīng)從醫生的建議，正確佩戴。否則可能會(huì )出現紅眼、眼痛甚至更加嚴重的眼部疾病。
