Since Jack The Ripper was never caught there is no way to discern his eye color. Short of a positive ID, we can only guess what the Ripper looked like.

If this question refers to the real Jack the Ripper, and not a fictional one, the answer would be that there were no known sightings of the murderer, and thus, it isn't known if he jumped off of ANY bridge. There is, however, a story that says that, every year on the 31st of December, a ghost appears by the Elizabeth Tower(formerly the clock tower, and known as Big Ben), and who stumbles out onto the WESTMINSTER bridge, climbs over the edge, and jumps into the Thames. This ghost is said to be that of Jack the Ripper. However, this is, A, a legend, and B, could, if it does indeed exist, be the ghost of any unfortunate soul.
