Is there a device with which humans can see ultraviolet light?

Best Answers

Humans don't need any “device” to see ultraviolet light. In a sense we can see a little way into it already. Thing is our corneas block ultraviolet light to protect our retinas from radiation burns. If you were to have your natural corneas replaced with synthetic ones then you'd have no problem seeing these colors. read more

Some wake up to find they can see colors far beyond the range humans are normally able to see. There is increasing evidence that patients who have cataracts, cancer or other eye problems treated by having their corneas surgically removed and replaced with artificial alternatives, often end up able to see colors in the ultraviolet range of the spectrum – colors of light visible to night-hunting raptors, some lizards and, oddly, ants, but not to humans. read more

On top of that, we humans lack (as far as is known) any sensory apparatus for detecting either uv or infrared, except the usual rods and cones by which we see ordinary visible light. Thus, whatever we see at extreme wavelengths is just the tail end of the sensitivity range of normal vision. read more
