Well, yes, in my opinion, it is possible to have cataracts when you suffer dehydration. Generally speaking, when the loss of body fluids, mostly water, exceeds the amount that is taken in, it can lead to the water go out of the body and there is no enough water for the organs to work. In that way, dehydration can occur. And it will just affect our eyes and lead to some eye diseases, such as bloodshot eyes, red eyes, even dark circles and eye bags under your eyes. On the other hand, cataracts can be caused by dehydration too. So just be careful about it.

Also, dehydration can cause the blurred vision because the body fluid is insufficient and the acid base is disturbed leading to the decrease of blood volumn and blood pressure. It is as well very likely that dehydration can lead to cataracts. The crystalline lenses of the eyes play a very important role in metabolism and keeping transparency and adequate amount of water is fatal to the normal funtion of crystalline lenses. The dehydration is one of the causes of the crystalline lenses becoming muddy, which will lead to cataracts.
