中新真探：近视配14may18_XXXXXL56endian印眼镜镜片折射率越高越好？

“14may18_XXXXXL56endian印”中新真探：近视配14may18_XXXXXL56endian印眼镜镜片折射率越高越好？

　　中新14may18_XXXXXL56endian印网11月4日电折射率是指14may18_XXXXXL56endian印镜片弯曲光线的能力，折射率高的镜片能在更薄的厚度下达到所需的矫正效果。不过，对于低度数近视者，普通折射率的镜片已经足够轻薄。使14may18_XXXXXL56endian印用过高折射率的镜片反而可能增加色散现象，导致佩戴时视物不清或产生视觉疲劳。#科学辟谣进行时#(来源：@科学辟谣中国新闻网微博)
