Why do I only have two eyes?

Do we need two eyes?
Two eyes help us gain a stereoscopic vision, i.e., the ability to register and make sense of three-dimensional space from any visual inputs. It also helps us to gain a wider angle, as with one eye, we would be able to see 150° while with both eyes, you get a 180° field of vision.
What animal had the first eye?

With two ears you can identify the direction from which a sound is coming. The same principle is used in direction finding equipment to locate the source of illegal radio transmission. With only one eye you would be unable to see objects in three dimensions and would not be able to estimate distances accurately.
Why are eyes and ears two senses?
Eyes and ears are two because their primary functions are source based input. To locate the source, we need two reference points. Two eyes and two ears give depth perception of the source. Whereas mouth input is not source location based but you bring the food to your mouth physically unlike eye and ear senses.
