中英眼镜度数换算

麻烦问一下JMS, 刚做了个眼睛测试。想拿回国用来配眼镜,不太清楚怎么换算成国内的度数? 想请问一下在英国配过的JMS 帮忙看一下。多谢!!



1. Sphere -2.00 (是国内的近视200度吗?)

2. Cylinder - 0.50 (是散光50度吗?)

3. Axis - 175.00 (配隐型175 度?)



再谢! :cn08:

3.那哪兒管隱形眼鏡的事,那應該叫。。。軸距?? or something like that

没有人知道吗?知道的JMS帮个忙。 :polite: :polite:

帮帮忙啦! :cn08:

拿回国正规眼镜店的人看的懂的… 都是专业的东西… 国内用的机子打出来也是这样滴~~

Axis应该是指瞳距吧,指两只镜片焦点之间的距离。配框架才需要这个参数。

2.00=200度
0.50=50度
175=眼睛到鼻子的距離,因爲每個人臉大小不同,肯定不是度數,要不然就是17500度,基本就瞎了... :cn14:

纯属,胡扯啊

瞳距175,难道是175mm?两个眼睛距离17厘米么。。。??

wiki查的结果,当然还是不能完全做准,要问专家才能最后相信,但毕竟,也比瞳距那么离谱的解释好一点



Axis



Spherical lenses just have a strength, such as +1.0D, or -2.5D.



Astigmatism, however, causes a directional blur. Here are two examples of the kind of blur you get from astigmatism. The letters are smeared out directionally, as if an artist had rubbed his or her thumb across a charcoal drawing.



A cylindrical lens of the right strength can correct this kind of blur.



A spherical lens is the same in all directions; you can turn it around, and it doesn’t change the way it magnifies, or the way it blurs



A cylindrical lens has both a strength and an axis. Turning it around so that the axis points in different directions changes the way it magnifies, and the way it blurs.



The axis specification on a prescription gives the orientation of the axis of the cylindrical correction, and it can vary from 1 to 180 degrees



原文(从解释axis的地方开始,有图解!):

可以从头看,关于prescription的完全解释+介绍

其实,这个,简单来说,是配镜的参数,与距离无关。但是具体做眼镜的时候用来干啥,我也没弄明白:p
