A frog's eyes help it swallow, since it pushes food down by blinking.

The longer version

Swallowing in a frog involves the eyes in a literal, mechanical way. The eyeball is large and sits in the roof of the mouth, separated from the oral cavity only by soft tissue, so it can be pushed downward.

When prey is taken, the frog blinks, and the retracted eye presses against the back of the mouth, helping to force the food toward the throat. This extra push matters because frogs lack the tongue-and-throat mechanics that mammals use, and their prey is often large and swallowed whole. The same action also keeps the eyes moist and protected during the struggle of a live meal.
