What is the eyesight of a crocodile? Under water? On the shore?

Crocodiles have protective films covering their eyes when underwater, so they can still see underwater. The crocodile's eyes look scary underwater because the protective film is transparent and slightly white. The moment the crocodile leaves the water, you can see the protective film in its eyes retracting. Of course, the premise is that it is close enough.

Crocodiles can see things on the shore underwater, but how clearly they can see depends on the water quality. For hunting in water, crocodiles rely more on the sensory contacts on their snout. The sensory contacts of large true crocodiles are more developed than those of alligators.

Extended information

The light accurately hits the crocodile's eyes. The aperture of the crocodile's eye is determined by using the eye wall refractor and the camera lens. It is found that all crocodiles have severe hypermetropia due to their focusing ability. The so-called hyperopia refers to the point where parallel light rays pass through the focus of the eye, and the retinal epithelial image blurs the vision. Crocodiles can see objects clearly at long distances.

Crocodile eyesight is seven times more precise than that of humans. Crocodile eyes have a tightly packed horizontal stripe called the fovea. The fovea is usually located in a circular area, but in crocodiles with horizontal stripes, they don't need the advantage of not moving their heads, and they lack the stamina for long chases on land or water, instead they rely on launching surprise attacks on their prey.
