A: Ability to see color.
1: Motion perception.
2: Copies all motion perceived.
3: Prediction motion- inferring through rational physics the action about to take place.
B: Ties pupils together for the ability to understand what one sees without getting confused. Without it, you would have three different eyes looking in three different directions and no idea what to focus on or what’s going on.
Sharingan has Extra Pupils
Now, the obvious factor that sets Sharingan apart from normal eyes are the extra pupils, isn’t it? But how would that help? Well, if rods are more common around the edge of the eye, increasing the amount of pupils would increase the number outer edges to be lined with rods.
So, if the center pupil were devoted entirely to cones to retain a sense of color, then the space in the other pupils would be specifically for rods in order to get a better perception of motion, which is what the Sharingan is.
The Byakugan
Also, the eye would have to be perfectly round, as opposed to the normal eye’s egg-shape
