The kingfisher solves this problem with a second fovea in each eye. Once the eyes are immersed in water, the image of the fish is focused on the second fovea in each eye. That means that there is stereoscopic visualization of the prey as it tries to dart away, an action that is usually not successful.
But, in order to keep the image focused on both foveae, the lens has to be oval and the second fovea has to be in the periphery of the eye at the edge of the retina.
