防蓝光树脂眼镜一半不能防蓝光

2017-09-05 07:41:43   中国青年网

本报讯(记者马辉)市场上被抽查的防蓝光眼镜片,有一半没有防蓝光的效果。昨天,市质监局发布安全风险预警:买防蓝光眼镜,要注意具体的透射比。

随着电脑、手机、LED灯的普及,屏幕蓝光对人眼的伤害日益严重;这种蓝光会刺激视网膜,导致视力下降,甚至是失明。最近,市质监局抽查了眼镜店、批发商、医疗机构的防蓝光树脂镜片,30批次的样品中,有15个样品的高能蓝光透射比超过90%以上,有的甚至高达98%,这样的镜片基本没防蓝光的效果。

为此,市质监局发布风险建议:由于防蓝光树脂镜片,技术难度大,市场上以次充好和虚假宣传问题突出;希望市民在买防蓝光眼镜时,要注意察看眼镜上有无防蓝光标识,还要看眼镜上,是否标注有准确的防蓝光指标和适用的工作环境;由于眼镜是否防蓝光,需通过仪器检测,目测无法辨识,所以,消费者不要轻信防蓝光的虚假宣传。
