Night vision cameras

Can Beardies see Pure-IR? Like from the LED's that night vision cameras and remote controls use? Most Mammals can't, but I can't find anything about Lizards...

I'm not sure exactly, but there is a good chance they can.

Beardies have more cones in their eyes than we do. Which in a general sense, means they can see wavelengths of light that we can't.

Although that doesn't mean they can see the whole spectrum of the lighting world, there is a possibility they can see IR.

I'm bored, I will go look up IR wavelength and try to check back over my notes on bearded dragons eyes.

Didn't take long.

The most important thing I needed to figure out, was which way the extra cones in reptiles eyes work. Do they let them see higher up into the spectrum, or lower.

It turns out it allows them to see higher up into the spectrum.

I can't find anything about pure IR. All I can find is Near-infrared, or NIR. NIR is just barely past the human spectrum. MWIR is also just barely outside of human eye capacity.

Now, I can't find any sources explicitly stating the how high (or Low) of a wavelength a bearded dragon can see, but it's safe to assume that with their better vision, they can easily see a light source just barely out of our visions capacity.

Wow, thanks for the info! I'm asking because we have webcams, and it would be nice to see at night. But I don't want to sacrifice his sleep. Tho it seems they don't get up to much at night.
