How many "eyes" fit across the average adults head?

The eyes should be one eye width apart from each other, and have one eye width on either side for a grand total of five.

In art andanatomy, the "eyes" that should fit across the average adults head is five.

The two eyes we have should leave a space roughly the size of one eye in the middle, and to the each of the sides of each eye, one more eye should fit.

Sorry for the horrible doodle but hopefully that gives an ok visual representation of my explanation
