Thread: How to see infrared...????

Does anybody know how to see infrared in naked eye,except digital camera, which means with glass or other material....????????????

Since the receptors in the eye are very insensitive to IR radiation, you need technical tools. One way is to transform IR into visible light. Another possibility is to amplify the IR by so much that even the eyes can see it. But this probably on works for the so called near IR. Thermal IR is probably unreachable by the latter technique.
