red light???

can corns see it? i use it 24/7 becuase it keeps my tank perfect, warm in day and slightly colder at night. but can they see it? if they cant then i will switch. the only reason it use it (except from the above) is i heard the cant actually see it, so as it simulates day/night for them.
does it?

It is my understanding that snakes in general see black and white due to a lack of functional cones in the retina of the eye. I believe that snakes have only one cone as described in [Snakes in Question: The Smithsonian Answer Book] . Here is breif description of how an eye uses rods and cones to see color(s).

Rods see in black, white, and shades of grey and tell us the form or shape that something has. Rods can't tell the difference between colors, but allow us to see when it's dark.

Cones sense color and they need more light than rods to work well. Cones are most helpful in the light (which is why we don't see color very well in the dark). The retina has three types of cones - red, green, and blue - to help you see different ranges of color. Together, these cones can sense combinations of light waves that enable our eyes to see millions of colors.

I hope this helps.

errr i was kinda hopin for yes or no

It means, no they can't see red light (as far as we know) and your red light will be fine to be on 24/7. That's what Neumann wrote in his reply, they only see in black and white so obviously can't see red light

Supposedly black, blue, and red bulbs are exceptable at night. According to most snake care sheets. I personally use a black bulb for the same reasons. I get good temperatures from it with a reflector.

how do u get a black light? i mean black is the absense of light.....so how does that work

A black bulb is like a uv bulb (I think).

A black light is another name for a UV bulb like you get on fairground rides and in clubs. It's black lights that make your white clothing glow in the dark.

As I understand it though snakes can see UV light better than the normal spectrum that we see so I'm not sure a black light would be suitable as a heating device at nighttime.
