If you look it up, Infer-red is in the visible range of wavel-leinths.

I think you are confused. Infra-red (I assume that's what you mean) is by definition beyond the red end of the visual spectrum. If you can see it, it's red, not infra-red.

The eye is designed to see the visible spectrum.
I am sure there are some species that see the infra red.

Inside your eyes are "rods" and "cones". One type is sensitive to B/W and the other is sensitive to colour, however they are only sensitive to specific wavelengths.
Infrared and ultraviolet are at the extreme ends of the light spectrum and outside of the sensitivity range of your eyes.

your eyes are only adapted to see certain wavelengths and infered light is to short of a wave length to be see by the regular eye....

because our sight sense doesn't perceive that wavelegth of radiation, at least not as light (you might as well ask why we can't see radio waves or microwaves)
even though we can't see infra-red we can still sense it as heat
