It's really impossible to say. Our eyes only react to light in the visible spectrum. Anything beyond that would only be speculation (no pun intended). You probably would not want to detect x-rays even if you could. If there were enough of them coming at you to allow you to "see", you'd probably be receiving a lethal dose.
On that note, what i really want to know is the difference in visual a hard x ray wave in comparison to a soft x ray wave. Any more input?
Our eyes only react to light in the visible spectrum.
When the lens becomes opaque due to cataracts, it may be surgically removed, and can be replaced with an artificial lens. Even with the lens removed (a condition known as aphakia) the patient can still see, as the lens is only responsible for about 30% of the eyes' focusing power.However, aphakic patients report that the process has an unusual side effect: they can see ultraviolet light. It is not normally visible because the lens blocks it. Some artificial lenses are also transparent to UV with the same effect. The receptors in the eye for blue light can actually see ultraviolet better than blue
Inferred: ... how strong/far would the vision extend?

I would love to hear what your thoughts are on the soft and hard x rays visible spectrum.

What we consider as color is extremely arbitrary.If I ask you "What is Blue?".Can you answer without pointing to a color?Can you be sure that your own sensation of blueness is the same as my sensation of blueness?Most people are trichromats (can see 3 colors), but there are a few that are dichromats, and a few that may be tetrachromats. Or, perhaps a great number of true tetrachromats. http://en.wikipedia.org/wiki/Tetrachromacy#Possibility_of_human_tetrachromatshttp://en.wikipedia.org/wiki/Color_blindnessMany dichromat people don't really realize their color perception is different than other people until special tests reveal color blindness.So, if a person was a trichromat, with vision into the UV or IR range, they might not realize any difference from others. In fact, with an extended range of color vision, what we consider as "visible light" might be more bland.A tetrachromat, or perhaps a pentachromat would just see additional colors, but it would be hard to describe the difference of what they see and what we see, except the extended range of visual perception. HOWEVER, there would be many materials that would be opaque in "visible light", but might be transparent, or partially transparent in other spectra. Do you have lead undergarmets?
Some animals, including birds, reptiles, and insects such as bees, can see near-ultraviolet light. Many fruits, flowers, and seeds stand out more strongly from the background in ultraviolet wavelengths as compared to human color vision. Scorpions glow or take on a yellow to green color under UV illumination, thus assisting in the control of these arachnids. Many birds have patterns in their plumage that are invisible at usual wavelengths but observable in ultraviolet, and the urine and other secretions of some animals, including dogs, cats, and human beings, is much easier to spot with ultraviolet. Urine trails of rodents can be detected by pest control technicians for proper treatment of infested dwellings.Butterflies use ultraviolet as a communication system for sex recognition and mating behavior.Main article: Ultraviolet communication --> http://en.wikipedia.org/wiki/Ultraviolet_communicationMany insects use the ultraviolet wavelength emissions from celestial objects as references for flight navigation. A local ultraviolet emissor will normally disrupt the navigation process and will eventually attract the flying insect.Entomologist using a UV light for collecting beetles in the Paraguayan Chaco.Ultraviolet traps called bug zappers are used to eliminate various small flying insects. They are attracted to the UV light, and are killed using an electric shock, or trapped once they come into contact with the device. Different designs of ultraviolet light traps are also used by entomologists for collecting nocturnal insects during faunistic survey studies.
Lol, I see what your getting at. So in short since you and I have never seen in these spectrum's we can only hypothesis what we would actually see.

Quote from: Voxx on 01/07/2012 16:50:01Lol, I see what your getting at. So in short since you and I have never seen in these spectrum's we can only hypothesis what we would actually see. It is not that, but that our sensation of colors is quite arbitrary, and merely a method our brain gives us to create contrast between different wavelengths of light in the scene.So, if you had a new UVA cone and a UVB cone, then you would get additional colors, that might give a purplish sensation, or perhaps something entirely different. And, then like other colors, these would be mixed with the existing primary colors to give a wider range of sensations. But, it wouldn't have to even give you a purple color. Just like you have a range of colors in the visible spectrum, you would differentiate out a range of colors in an extended spectrum (as well as those combined with the existing spectrum).I think Plato discussed the difficulties of explaining color to someone that only saw in Black and White. You could hold up a yellow pencil, and the BW person would agree that it is a pencil. Then hold up a red pencil, and it is still a pencil. In fact the BW person would see different shades of colors so he would agree that they are different. But, it would be difficult to explain the fundamental difference between red and yellow.Of course, we can make sense out of a black and white TV show or movie. But, if one sees a show first in BW, then later in color, the true colors in the scenes can be surprising.Quote from: Voxx on 01/07/2012 16:50:01Study Says Eyes Evolved for X-Ray Visionhttp://news.rpi.edu/update.do?artcenterkey=2486Interesting. Although, it is not true X-Ray Vision, but rather that one is adapted to look past objects. So, if you are hiding in a leafy camouflage area, you see past the leaves to the scenery beyond, and your brain automatically subtracts out the leaves.
There is an old trick with upside down glasses that causes the brain to reverse up and down. I wonder if it's possible to do something similar with colours. If trees were presented to us as red, would we eventually call red "green" because we know trees are green?
I am curious to why we depict UV to be in more of a purple scenery and IR to more of a red scenery then? Does this mean colour is an illusion in itself? Any further explanations?
Some people even "see" numbers in different colours!http://en.wikipedia.org/wiki/Synesthesia
To comment on Clifford's comment, when we look at an X Ray we see black and white. Does that mean that in the Radio, Microwave, X Ray and Gamma Ray visual area's we see black and white? If of course you would be able to see within those spectrum's seeing as the chart you showed have the blacked out range within that area?
I wonder how long it will be until more medical x-rays also start using color.
By the way, as far as your poll,If you make it an either-or question. Then the answer is that one is far better off seeing in the visible spectrum. There may be benefits of adding additional spectra, such as IR. But, I doubt many people would wish to give up the ability to see visible light for the extended spectrum.Actually seeing in UV would be different from fluorescing (releasing visible light) when struck by UV. Most fluorescing is only visible in the dark. Would it be possible to filter out the overwhelming visible light when trying to view both UV and visible light?
