带一些相对便宜或者质量一般的眼镜片会对眼睛有很大伤害么

虽然也知道眼镜片行业水分很大 但是毕竟 也有相对价格高低之分 相对便宜的镜片 比如50左右 对眼睛有什么伤害么? 我只知道 价格高低最明显的是厚度 其他的呢 带一些便宜的 会对眼睛有伤害? 增加度数? 不大懂 希望明白的给说说
不大懂 冒昧问一下 1.49 1.56 哪个好 我是300°近视 以前都没注意过折射率的问题

Answer 1

是有区别，但是如果你的度数的数据准确了，那也不要紧，好的镜片体现在膜层上，品牌镜片加膜工艺好，做出的膜层美观，并且耐用，不容易脏，防水性能好，现在镜片大多是用旋转工艺来做的，好的厂家做出来的镜片里面没有什么杂质。透光率好。成像效果也好
像你的度数不算很高，用个中等折射率的就行了，还要看你用的是什么框架。如果是无框的话就最好不用那么薄的，免得容易蹦边。1.56就差不多，最实用的。
如果你追求性价比的话1.56是比较好的选择，大概七八十块钱就差不多了。两年换一次吧

Answer 2

不会，25元一副的1.49白树脂片也是不错的，只要度数准确，配镜合适，一样对眼睛不错。50元一副的1.56加膜镜片一样好用。

Answer 3

1.49厚，1.56薄一点，1.60、1.67 等等，更薄。
同个牌子，当然是越薄越贵。
镜片质量好、光度准，不代表一定就贵。正规镜片厂家的镜片，也分档次的嘛，也会有廉价实惠的系列。
质量、光度一定保证要好、要准确。配眼镜的店要可靠。
