My snake might be a ninja

Just a quick question..

Can snakes see light? I know they sense infrared or see infrared, whichever. But I have this regular reading lamp that I turn on sometimes to check his enclosure at night. I don't keep it on all the time, but I do notice that whenever lights are on at night, he never comes out. Or if he does come out, he moves from hide to hide like a sneaky little ninja lol.

Any response will be helpful! :D

Yes snakes can see light :)

They sense heat (infrared radiation) with heat pits but they see with the normal light spectrum with thier eyes. :)

Oh! Thank you! I should probably back off the flash photography then. :O
