Now how do those animals deal with it? Well, they just do, because their brain works with it differently. Which brings me back to my point that it would be an extension of your existing sight. The animals which naturally have the ability to see wider spectrums don't suddenly have another sense, it's an extension.

You know also that people can see a bit of low-range-infrared? Just thought I'd mention.
how could anybody know that some animals see more colors than we do?
