Why do ducks have small eyes?

Ducks' eyes are not particularly small compared to their body size. In fact, they have relatively large eyes that are well-suited for their lifestyle and environment. Ducks are known for their excellent vision, especially in water. Their eyes are positioned on the sides of their head, giving them a wide field of view. This allows them to see predators, food, and other objects both in the air and in the water. Additionally, ducks have special adaptations in their eyes that help them to see underwater. They have a nictitating membrane, or third eyelid, that acts as a protective layer over the eye when they dive or swim underwater. Their eyes also contain a high number of cone cells, which are responsible for color vision and visual acuity. This enables ducks to distinguish between different colors and see details clearly even in low light conditions. Therefore, it is not accurate to say that ducks have small eyes.
