How might the differences between a sheep, cow and pig eye be of benefit to each of the animals?

Question

**This is a science lab that i need help with. THANKS!

thats pretty much the only difference between them is size..i'm not sure how to answer it. do you think the size of the cows eye (since its the largest eye of the three) has less vision than the other two or the opposite?

Answer 1

What are the differences between their eyes? As far as I can find they're about the same (except size).

If you tell me the diffrences I'll tell you the benefits.
