Can your eyes see infrared

Answer 1

The naked eye cannot see infrared light. The naked eye can see red. Both red light and infrared light are two different colors. Infrared light can't be seen, because it's wavelength is too long for the naker d human eye to detect.

Though the above response is correct in most instances, there are conditions where the eye can indeed see near-infrared light. Two examples will be provided - both involving laser light. An Alexandrite laser is tunable from 740 to 780 nm. When laser light is emitted from this laser, it is clearly visible. This is in part due to the high intensity of the light combined with the fact that the red cones of the eye have an extended response tail that still sensitivity beyond the visible spectrum from 400 to 600 nm.

Another more intriguing case is that of a laser rangefinder emitting at 1064 nm (much further out in the near-infrared spectrum). For many years, military LRFs used Nd:YAG lasers for rangefinding to targets up to several miles. Reports from soldiers stated they could see this laser light. Experiments were conducted and found to verify this. When the eye is dark adapted (night viewing), the rods become the primary sensor. It's why you can't see color in dark conditions. Under these scoptopic conditions, the eye is much more sensitive to light in general.

So the eye under certain conditions can indeed see infrared.
