眼睛不僅是靈魂之窗，生理上也是一個複雜而非常重要的器官，因為我們需要通過眼睛與外界接觸和溝通。
為了保護這重要器官免受衰老，我們可以採取以下一些步驟，令視力更清晰銳利。
定期檢查眼睛、運動和均衡飲食等非常重要。有需要也可以服用一些補充劑，幫助保護您視力和預防眼疾(包括青光眼、年齡相關性的黃斑變性（AMD）和白內障)。
關於維他命
β-胡蘿蔔素（維他命A的一種形式），維他命C和E，以及礦物質鋅都是對眼睛健康非常重要的營養素。 2010年一項有關抗氧化劑、微量營養素和植物化合物對抗眼疾的研究結論是，補充維他命A，C和E以及鋅可有效預防高風險的老年黃斑病變。其他研究表明，缺乏維他命C和E與青光眼有密切聯繫
奧米加脂肪酸
奧米加三非飽和脂肪酸主要存在於魚類、亞麻籽、菜籽油和核桃油等，這些脂肪酸能有效降低患白內障的風險，防止老年黃斑病變的情況惡化。澳洲一項有3,654長者參與為期十年的研究表明，飲食中如果能包含魚類和奧米加三脂肪酸，可防止早期老年黃斑病變。另外一項較短的研究則指出，在年齡介乎45至77歲的健康人群分別服用90天奧米加三DHA補充劑或安慰劑，服用DHA的一組經治療後視力明顯更清晰。
強力抗氧化劑與視力的關系
葉黃素和玉米黃質是具有抗發炎特性的強力抗氧化劑，兩者是組成眼部黃斑色素的重要成分 - 這是保持視網膜正常工作和視力敏銳的關鍵因素。研究表明，補充這兩種天然類胡蘿蔔素(蔬菜或水果中主要的紅、黃、橙和綠色)能減少視覺疲勞癥狀，提高視力，尤其是光線對比敏感度(例如需要長時間面對電腦熒光幕)有大幅提升。
葉黃素和玉米黃質還有助保護視力。賓夕法尼亞眼科學院的科學家對補充劑進行了詳細審查，研究支持葉黃素和玉米黃質對促進視力和保持眼睛健康非常重要，並有助降低患上老年黃斑病變和白內障的風險。
太陽眼鏡除了酷還非常有用
我們會采取防曬方法讓皮膚免受太陽光有害射線影響。同樣地我們也可透過攜帶太陽眼鏡免受有害射線影響而達到保護眼部的目的。
See into the future
Whether you think of them as windows to the soul or as complex ocular organs, the eyes are our principal means of taking in the world.
Luckily, there are steps we can take to increase the chances that our vision stays clear and sharp as we age.
Get regular eye exams, exercise, and eat a balanced diet. To help protect your sight and prevent diseases of the eye including glaucoma, age-related macular degeneration (AMD), and cataracts, incorporate these supplements into your daily regimen.
The View on Vitamins
Beta carotene (a form of vitamin A), vitamins C and E, and the mineral zinc are all important nutrients for healthy eyes. A 2010 study of the effects of antioxidants, micronutrients, and plant chemicals on the progression of eye diseases concluded that supplements of vitamins A, C, and E, along with zinc, may work to prevent advanced age-related macular degeneration in people at high risk for the disease. Other research indicates there may be a link between glaucoma and deficiencies in vitamins C and E.
Ogle Omegas
Found in fish, flaxseed, canola, and walnut oils, omega-3 fatty acids may lower the risk of cataracts and prevent the progression of macular degeneration. A 10-year study of 3,654 elderly Australians indicates that diets including fish and omega 3s may protect against early age-related macular degeneration. A shorter study, in which healthy people ages 45 to 77 were given 90 days of supplementation with either a placebo or the omega 3 docosahexaenoic acid (DHA), found that those in the DHA group who wore corrective lenses experienced sharper vision after the treatment.
Ante Up with Antioxidants
With anti-inflammatory and antioxidant properties, lutein and zeaxanthin make up the pigment of the macula — a part of the retina that’s critical to sharp vision. Studies have shown that supplementation with these two carotenoids—natural red, yellow, orange, and green pigments found in fruits and vegetables—can help reduce symptoms of visual fatigue and improve vision, particularly contrast sensitivity, in people who spend long hours in front of a computer screen.
They can also help protect your eyesight into the future. A scientist at the Pennsylvania College of Optometry reviewed studies on dietary supplements to promote eyesight and eye health, and concluded that the research supports the use of lutein and zeaxanthin “to promote optimal visual function and decrease risk for AMD and cataracts.”
Beyond Cool
Most of us are diligent when it comes to protecting our skin from the harmful rays of the sun.
Luckily, you can lessen your chances of developing these eye problems and look hip at the same time, just by putting on sunglasses.
