And oxygen deprivation in the retinal cells impairs their ability to process light, causing greyed out vision or temporary blindness.

视网膜细胞缺氧会削弱它们处理光线的能力，导致视力变灰或暂时失明。

These instructions are inserted into specific eye cells called retinal ganglion cells, bypassing the damaged retinal cells, and allowing visual information to be transmitted to the brain when the modified cells are exposed to light.

这些指令被插入到称为视网膜神经节细胞的特定眼细胞中， 绕过受损的视网膜细胞，并在经过修饰的细胞暴露于光线时将视觉信息传输到大脑。
