gray cataract的意思|示意

And overhead, with a rustling and loud noise, the gray clouds rush westwardly forever, until they roll, a cataract, over the fiery wall of the horizon.

头顶上，伴随着飒飒的声音，灰色的云终古不息地飘向西方，直飘到天边那堵火红的墙上方，翻卷成一场瀑布般的暴雨。

The word 'glaukos' means gleaming, bluish green or gray, perhaps describing the appearance of a blind eye if glaucoma (cataract) derives from it.

Glaukos词意思是发光，蓝绿色或灰色，或许描述了瞎眼的样子，是否青光眼（白内障）就来自它。
