Most frogs have large protruding eyes, giving them almost 360' vision. This is needed as they don't have very flexible necks. They can see in colour and can have good vision for movement, even if far away.

Many frogs are nocturnal so have good night vision. They have a mirror layer in the back of the eye (called tapetum lucidium) that lets them reflect light at night,known as 'eye-shine'. This gives them a kind or search light for hunting by.

Deferent species have different sensitivity to light depending on their habits and habitats. This can be determined by the numbers of 'rods' and 'cones' on the frogs retina (back of the eye). Rods are sensitive to light and cones detect colour. Frogs have different colour vision to humans. They find it hard to see red light, they respond best to yellow light.

Tadpoles have eyes at the sides of their heads, but they move forward during metamorphosis. When a frog is underwater their eyes have to change because of the different refractive properties. Frogs focus by moving the lens rather then it changing shape, like in mammals.

Vision is the main sense used while hunting. Frogs have good depth and movement perception. Also because of their wide vision range they can look about without moving, so don't scare off prey. But they find it hard to see still prey.
