眼睛防晒学问多 饮食养眼很重要
发布时间:2011-07-13      来源:新华网
    夏日艳阳高悬,紫外线热情“关照”,很多想保护眼睛的人认为,戴上太阳镜就万事大吉。眼科专家提醒,太阳眼镜“治标”,饮食养眼“治本”,双管齐下更有效。

  研究表明,眼睛是人体对紫外线最敏感的部位,在医学上被形象地称为“靶器官”。银川市中医医院眼科医师李英说,眼睛长期受紫外线照射,会导致提早老化和其他眼疾。防止紫外线侵害,除佩戴一款质量上乘的太阳镜外,通过饮食调养不失为一种好方法。

  要想眼睛明亮,就要多加颜色。据李英介绍,长叶莴苣、甘蓝、西葫芦、西兰花、猕猴桃等黄绿色果蔬中富含叶黄素和玉米黄素,对眼睛很有好处。这两种色素会在眼睛后部的光敏感组织中积累,这些组织通过过滤蓝光保护眼睛。

  另外,维生素C是抗氧化剂,维生素A对眼睛也大有裨益。专家提醒,在日常菜单中可增加西红柿、胡萝卜、红薯、菠菜、土豆等蔬菜,以及浆果、甜瓜、木瓜、桃、草莓等水果。

  高温天气里,喝夏季养生茶可起到降暑明目效果。李英说,可多喝些枸杞、菊花、决明子等配成的药茶,对缓解眼睛疲劳效果不错。
