What if a Human had infrared sensitive eye?

Answer 1

Now, if a human could see infrared AND visible light AT THE SAME TIME, I imagine that their life would be pure hell. Not only would they see our colors and everyday things, but they would also see weird mixtures of red, purple, white, etc. However, if they could somehow switch between IR mode and visible light mode, then the IR mode would allow them to "see" heat. Heat energy is usually radiated away along the Infrared wavelength of the electromagnetic spectrum, so this person would be able to see things with a lot of heat. For example, steam in the air or a person or something else warm would look as if it's red/orange/yellow, whereas ice or a table or something cold would look purple. Glass, on the other hand, would appear to look black, regardless of how hot it is, since glass absorbs IR radiation. Some things would just be invisible, since they neither absorb or reflect IR radiation, such as plastic bags or other things.

But thats all an IR eye can do. They would be able to see heat, but thats it. I thought you asked this question before, but it may have been someone else.

Hope that helps.

Answer 2

If a human had the ability to see infrared, I would imagine that he/she would see more colors than we currently do (presuming the cones were present to perceive those wavelengths). What they would look like, obviously I don't know, since *I* can't see into the infrared. Sounds cool, though :-)

Answer 3

Well - it wouldn't be as one poster put it, pure hell. Think about it- your eye does detect a wide range of electromagnetic radiation, and your brain processes the information into a coherent, meaningful "image" (that opens up a whole other conversation about what it means to "see").

There's nothing special about the spectrum range known as "visible light", aside from the fact that our eyes can perceive it. If your eyes could perceive the infra red spectrum, it would just be another visual quality. One could speculate how this additional information would be cognitively perceived -- perhaps it would modify our current color vision -- or maybe like rods and cones work in different lighting conditions, infra red would only be consciously perceived when light conditions made it useful. This seems like the more likely scenario. You could see infra red vision kicking in in low/mixed light conditions to perceive predators and prey that would otherwise be camouflaged

Answer 4

If the present human visual spectrum were extended into the infrared, we would gain the benefit of 'night vision' goggles, and be able to visually detect heat signatures that our unaided eye cannot now detect. If we had to sacrifice any of our current visual spectrum to get it, it would usually be a net loss. I we had to sacrifice visual acuity (resolution), it would definitely be a net loss. God or evolution (you choose) makes wise choices.

Answer 5

Then he can see the dark
sensitive eye then he can see the human aura
even the ghost maybe

Answer 6

that,that would be kool !!!
