Uchiha clan eyes

This is the normal uchiha eye
The normal eye for an Uchiha clan member resembles any normal human eye with iris, pupil and sclera.
Sharigan tomeo 1 This is the first variation of a partially developed Sharingan eye. The clan members pupil will turn red and develop one of the wheel swirls. When Uchiha Sasuke finally activated his Sharingan, his left eye took this form.
Sharigan tomeo 2 This is the second variation of a partially developed Sharingan eye. The clan members pupil will turn red and develop two of the wheel swirls. When Uchiha Sasuke finally activated his Sharingan, his right eye took this form.

Sharigan tomeo 3 This is the final normal form of the Sharingan eye. The clan members pupil will turn red and develop three of the wheel swirls in both eyes. In this form the clan member can read Genjutsu, Taijutsu and Ninjutsu, learn how the skill is done and then copy it to be used later. This form can also initiate the Mangekyou "Kaleidoscope" form.

Mangekyou Partially Developed This variation is the Mangekyou (Kaleidoscope) form while not fully changed. Sasuke initially caught a glimpse of this version of Itachi's Mangekyou which differed from his later version.

mangekyou sharingan This is the rare Mangekyou (Kaleidoscope) form which is said to only appear in a few Uchiha members. Uchiha Itachi was able to finally master this form during the period he killed his clan. In this form Itachi is able to use the Amaterasu and Tsukuyomi Doujutsu techniques. (must kill best friend for mangekyou)
