CYANOMN1VORE
Dude even with glasses opponent is looking into sharingan. Chakra is transferred, you look into magic eyeballs and chakra get transferred to your system. Rest of the genjutsu work with chakra transfer system so why sharingan the better tool for genjutsu won't work the same way?
CYANOMN1VORE:Eye 'contact' genjutsu. What if there isn't eye contact? Is it any worse then watching an Uchiha's feet which was and still is the main way 'regular' people counter Uchiha.
