The latest part of the study, which involved about 4,000 participants, also looked at the effect of replacing beta-carotene in the supplements formulation with lutein and zeaxanthin because of studies that found former smokers who take beta-carotene have a higher incidence of lung cancer. Researchers found a 20% improvement in progression to advanced AMD with the replacement, said Emily Chew, deputy director of epidemiology and clinical application for the National Eye Institute, a branch of the National Institutes of Health.
这项研究的最后一部分共涉及约4,000名参与者，它探讨了用叶黄素和玉米黄质来代替补充配方中β-胡萝卜素的影响，因为众多研究表明，曾经是烟民的人摄入β-胡萝卜素后，罹患肺癌的风险会更高。美国国家眼科研究所流行病学与临床应用部门副主任埃米莉•周(Emily Chew)说，研究人员发现，在服用替代营养素后，有20%的患者病变至年龄相关性黄斑变性晚期的过程有所改善。美国国家眼科研究所是美国国立卫生研究院的一个分支机构。

Dr. Chew said the AREDS study researchers recommend replacing the beta-carotene in supplements with lutein and zeaxanthin. Benefits from the supplements have been found only in people who are at high risk for advanced AMD or already have it in one eye.
周博士说，年龄相关性眼病研究的工作人员建议用叶黄素和玉米黄质来替代补充配方中的β-胡萝卜素。但该配方的益处仅仅只在那些晚期年龄相关性黄斑变性高发人群或者已有一只眼患上此疾的病人身上显现。

Some eye experts say omega-3s, found commonly in fish and nuts, appear to play a protective role in eye health with both the retina and cornea. This includes help with the dry eyes that many people, especially women, experience in their 50s. Anne Sumers, a spokeswoman for the American Academy of Ophthalmology and a practicing ophthalmologist in Ridgewood, N.J., said consuming flax seed, either as a pill or sprinkled on food, can help treat dry eyes.
一些眼科专家说，常见于鱼类和坚果中的Ω-3脂肪酸看来能对包括视网膜和角膜在内的眼部健康起到保护作用，包括对干眼病也有帮助。许多人在进入50岁后就易患上干眼病，尤其是女性。美国眼科学会(American Academy of Ophthalmology)发言人、新泽西州瑞吉伍德市(Ridgewood)执业眼科医师安妮•苏美尔(Anne Sumers)说，进食亚麻籽，不论是吃药片还是把亚麻籽撒在食物上吃，都有助于治疗干眼病

Too much time staring at electronic screens has given rise to another problem: computer-vision syndrome. To relax the eyes, some experts recommend that for every 20 minutes spent staring at a computer, people should take a break for 20 seconds and look at least 20 feet away, ideally out a window.
长时间盯着电子屏幕看也引发了另一个问题：电脑视觉综合症。一些专家建议，为了放松双眼，人们在盯着电脑工作的时候，应该每隔20分钟就休息20秒、并远眺至少20英尺，最好是看看窗外。

The decision to go to an optometrist versus an ophthalmologist is a personal one. Ophthalmologists are medical doctors who spend most of their time managing eye diseases and performing surgeries rather than prescribing eyeglasses. Optometrists' main focus is prescribing eyeglasses, as well as screening for eye diseases. If getting an eye checkup, be sure -- particularly if you're 40 and over -- that the optometrist does a comprehensive dilated eye exam to observe the pupil opened up in order to see the retina.
至于到底是去看验光师还是眼科医生，这就看个人选择了。眼科医师是医学博士，他们将大部分时间都花在治眼疾、做手术上而非配眼镜上。验光师则专注于校配眼镜，他们也负责检查眼疾。如果想要进行一次眼科检查──尤其是如果你已年届40或年过40的话──那一定要验光师实施全面的散瞳眼底检查，即观察放大后的瞳孔以检查视网膜的情况。
