Eyesight

[Green Bean]

How exactly do snakes see? Do they see in terms of heat or in color. When they are in the blue, it's considered they have a harder time seeing. If they see in heat, how exactly does it become harder to see if you are in the blue? I hope that makes sense...

Sight: Although most snakes have good eyesight, snakes don't rely only on sight alone. Most snake eyes are best at detecting movement. Snakes have been known to glide past creatures that remain motionless. Snakes don't hypnotise their prey: Perhaps this myth arose because snakes don't blink and animal prey know that standing still is the best chance to avoid being attacked.

While some snakes may see some colours, most don't appear to sense colour the way we do. Perhaps this is why snakes don't display vivid colour changes during mating like some other reptiles.

But some snakes have very good vision. Some can change the focus of their eyes to create a clear image. Some (like Vine snakes) have good 3-D vision to judge distances because their eyes are at the front of the head; these snakes hunt in the day or move around in trees. Others with eyes on the side of their heads have a wider field of vision. Most night-hunting snakes have larger eyes and vertical pupils which enhance night vision (although some day snakes also have these). Some burrowing snakes like blindsnakes have simple eyes that can only detect light and dark.
