即使有些人天生失明，但他们大脑的视觉区域不会消失。取而代之，大脑会重新调动其他感官。
But the visual areas of the brain, even in someone born blind, do not entirely disappear; instead, they are redeployed for other senses.
所以即使你与一条双目失明的毒蛇不期而遇，千万不要认为你是安全的。 （哈利啊哈利你当初是怎么打败蛇怪的呢？？）

然而最新研究表明，即使是个很小的免疫反应都有导致失明的危险。
However the new study suggests that even a small immune response could lead to blindness.
