Can cataract be contagious ?

[Illiopolis]

I am wondering if the cataract is contagious, just like the red eyes.

I've never heard that cataract can be contagious. It is often caused by the age, gene and some other injuries to the eyes. So don't worry.

No,it can't be contagious. Cataract is usually caused by aging,gene,radiation or trauma.
