都市人無論工作定消閑都會對住電話或電腦,長時間望電子產品會造成眼睛疲勞,甚至視力變差,想保持雙眼明亮,除咗有良好嘅生活習慣之外,都可以從飲食入手,好多人第一時間會諗起胡蘿蔔,但除此之外其實仲有好多嫁,一齊嚟睇睇仲有咩例子!

魚類-豐富Omega-3及DHA

魚類含有豐富嘅Omega-3,可以預防黃斑病變,同埋有助淚水正常分泌,改善眼乾症狀;亦能夠舒緩眼內壓力,防止誘發青光眼,改善視覺靈敏度。蘊含豐富Omega-3及DHA嘅深海魚有吞拿魚、三文魚、沙甸魚、鯷魚等。

 
藍莓-花青素
市面上有好多護眼保健食品有藍莓成份,因為藍莓含有豐富嘅花青素,有助維持眼球微血管嘅彈性同幫助視網膜上嘅視紫素合成,提供充夠營養同氧氣畀視網膜細胞,維持眼睛健康,而且藍莓具抗氧化功效,能夠幫助眼部血液循環同埋視力敏銳度。
 

羽衣甘藍-葉黃素、玉米黃素及維他命C
羽衣甘藍有「綠葉菜之王」之稱,含有豐富葉黃素同玉米黃素,特別喺天然環境下,呢兩種營養素可以吸收多餘光能,防止藍光破壞植物組織,同時過濾有害嘅藍光破壞眼細胞同視網膜。葉黃素喺體內無法合成,會隨住年紀大而流失,所以要攝取多啲含有葉黃素嘅食材。羽衣甘藍同時含豐富抗氧化維他命C,都對眼部健康有益。
除咗羽衣甘藍,以下綠葉菜都含有相當份量嘅豐富葉黃素同玉米黃素:粟米、菠菜、芥蘭、番薯葉、紅菜頭葉等,讓大家有多幾個選擇。
 

杞子-玉米黃素牛及磺酸物質
杞子清肝明目有唔少人都知,佢可以保護視網膜嘅視神經節細胞,以對抗青光眼。葉黃素同玉米黃素係視網膜形成嘅主要物質,而杞子能夠增加血液中嘅抗氧化物玉米黃素,發揮保護黃斑嘅效能。杞子仲含有一種牛磺酸物質,有助防止視網膜血管增生,用杞子嚟泡茶或者煲湯飲用都係好方法!
