Seeing well in the dark is the major function of an owl's eyes. Eye size is very important for seeing at night. Because an owl's eyes are so large, they have a large surface area to collect light. The light hits specialized cells in the eye that help animals see in low light levels. These cells are called rod cells. Owls have many more rod cells than other animals.
So, the correct answer is option A.
