If you have brown eyes, the cells in the meshy front of your iris are full of pigment.

果你的眼睛是棕色的，你的虹膜前状的细胞会满色素。

If you have blue, or blue-grey, there's not much pigment in that meshy layer at all.

果你你的眼睛是蓝色或蓝灰色的，状层上根本就没有多少色素。

But that's totally covered by a meshy front layer, and that's where things vary from person to person.

但它完全被一个状的前层所覆盖，而这就是因人而异的地方。
