根据美国一项新研究，戴太阳镜或有沿帽子可以显著减少紫外线刺激，减少白内障发生。十年前一项研究显示，不戴太阳眼镜或有沿的帽子的渔民罹患白内障的机率是其他渔民的３倍。另一项追踪研究发现，即便是难得在户外活动的人，如果不遮挡阳光对眼睛的直接照射，他们罹患白内障? According to a new study in the United States, wearing sunglasses or along the hat can significantly reduce the UV stimulus and reduce cataracts. A decade ago a study showed that fishermen without sun glasses or edge-hat were three times more likely to have cataracts than other fishermen. Another follow-up study found that even people who enjoy outdoor activities have cataracts without blocking the sun’s direct eye exposure.
