Sharingan Eye Variations and transformation

Normal Uchiha Clan Member Eye
	The normal eye for an Uchiha clan member resembles any normal human eye with iris, pupil and sclera.
Sharingan partially activated - One Comma
	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.
Sharingan partially activated - Two Comma
	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.
Sharingan fully activated - Three Comma
	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.
Sharingan - Uchiha Itachi Mangekyou (Kaleidoscope) Form
	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.
Sharingan - Hatake Kakashi Mangekyou (Kaleidoscope) Form
	This Mangekyou Sharingan form was revealed by non-Uchiha clan member Hatake Kakashi. Whether this form is due to Kakashi or some inheritance from what Uchiha Obito was capable of is unknown. Using the eye, Kakashi can use a technique which appears to collapse space in around a focus point and transport it to another location.
Sharingan - Uchiha Madara Mangekyou (Kaleidoscope) Form
	This Mangekyou Sharingan form was attained by Uchiha Madara. After developing the Sharingan, Madara and his younger brother trained against one another and eventually awakened their own version of the Mangekyou. The use of these eyes increased the brothers' strength and allowed them to take over leadership of the clan. Unfortunately the usage of the eyes lead Madara to lose his vision.
Sharingan - Uchiha Izuna's Mangekyou (Kaleidoscope) Form
	This Mangekyou Sharingan form was attained by Uchiha Madara's younger brother Izuna. After developing the Sharingan, both brothers trained against one another and eventually awakened their own version of the Mangekyou. The use of these eyes increased the brothers' strength and allowed them to take over leadership of the clan.
Sharingan - Uchiha Madara's Eternal Mangekyou (Kaleidoscope) Form
	Unable to accept being blind, Madara did everything he could to regain his vision. A desperate Madara eventually removed his brother's eyes to use as his own. As a result, Madara awakened a new more powerful set of eyes which allowed him to see the light once again. This new eye form would combine the look of both he and his brother's Mangekyou Sharingan.
Sharingan - Uchiha Sasuke's Mangekyou (Kaleidoscope) Form
	Itachi sought to protect his younger brother from Uchiha Madara. To that end he used a jutsu to implant his Mangekyou and its techniques into Sasuke. When Sasuke's Mangekyou was initially activated, it resembled the version seen in Itachi, due to Itachi's sealing of Amaterasu into Sasuke's eye as a defense mechanism. Later Sasuke's Mangekyou took on its own look. Even though it bore a new shape, Sasuke was still able to utilize Amaterasu.
