Can wearing sunglasses prevent sharingan?


If one is wearing dark black sunglasses, then how will eye contact work?
Sharingan user won't be able to tell when he has eye contact? I haven't
finished shippuden yet, so may be answer lies ahead but I am curious.




The only known way to avoid the effects of the _Sharingan_ have been to avert
or completely cover one's eyes, or at least be able to block out the
vision/chakra reach of the technique. However, it's not necessarily the case
that just doing that alone will help.

Given that the _Sharingan_ 's main strength are powerful _genjutsu_ (illusion
tactics), it's well within the realm of experienced/expert _Sharingan_ users
to be able to control more senses than just vision, and thus, averting eyes
alone isn't quite enough to protect from the illusions. I don't think
sunglasses would help - you can still see through them, after all, so you
would be able to have your vision compromised just as if you weren't wearing
any.

Since you're still getting through the series, I won't spoil anything for you,
but the fact that averting eyes isn't enough to avoid the powerful _genjutsu_
produced by it plays a pivotal role towards the end of the series.
