How far can rats see?

no. i used to own 4 rats and i asked the same question i read it in a book on rats.

rats are very nearly blind they can only really detect movement and sound properly.

TOTALLY NOT TRUE! YOU KNOW NOTHING ABOUT RATS THEY SEE IN SHADES OF GREEN AT NIGHT THE HAVE LIKE THOSE NIGHT VISION GOGGLES BUILT IN THEIR TINY TENY BRAINS!!!!!!!!!

Wow, you guys^ are funny! I have read that they can see blues and greens in the day, but a lot of sources say different things...
