no one
they just help you see better because there are millions of rods and cones in your eyes, but it all just works together
Same reason as humans do. They need their eyes to see.
u probably need to eyes so it is easier to see. close one eye. u cant see like, the other half (get it?) and animals like deer, antelopes etc. need two eyes to watch for predators when they eat :)
no they don't have eyes either instead they have feelers
To see.
If your eyes can't see, you either need laser or glasses. I have glasses.
to see with their eyes they do
no, you can see it with you're eyes
rods
Potato eyes and the eyes of needles. Also, the eyes on the back of the U.S. one dollar bills.
To open the eyes
Lots of people can. My mum can. I can if I shut one of my eyes. Some people can not see with one of their eyes so have to see with only one. Lots of people can.
