What does a snakes vision look like?

They discovered that most snakes have three visual pigments, two of which are in cones.

Why do snakes stare at you?

In addition to their colour vision, many snakes have developed a sensitivity to UV light, allowing them to see in low light conditions. This adaptation was found in the majority of snakes analysed in the study.

Can snakes see like humans?

With the exception of a few species that have adapted to daytime hunting, most snakes do not see well. Generally they can see shapes but not details. This poor eyesight probably owes to their evolutionary history as burrowers, living in the dark where eyes weren’t much use.

Snakes have no visible ear, so they don’t hear sounds as we do. But it’s not quite right to say that snakes are deaf.
