据一项来自美国的测试表明,金属眼镜框会明显导致电磁场增强,令使用者对辐射的吸收率增加。这是因为金属眼镜架是一种良好的导体,它会将手机产生的辐射导入眼睛和大脑,影响视力。电磁场的辐射的确能够通过一定的介质和导体进行传播,但合格手机的电磁辐射量符合规定标准,对人体无害, According to a test from the United States shows that metal frames will obviously lead to enhanced electromagnetic field, so that users increase the absorption of radiation. This is because the metal frame is a good conductor, it will be mobile phone radiation into the eyes and brain, affecting vision. Electromagnetic field radiation can indeed be transmitted through certain media and conductors, but the amount of electromagnetic radiation of qualified mobile phones meet the prescribed standards, harmless to the human body,
