here is the thing, it makes absolutely no sense to even remotely believe that using the chidori would cause a byakugan user to have tunnel vision. a normal eye can not see anywhere near 360 degree. its absolutely illogical to believe that the byakugan wouldn't negate the tunnel vision. The visual field of the human eye spans approximately a 170 degrees of arc with around 100 degrees for the peripheral vision. here is the thing, a person with tunnel vision simply has a loss of peripheral vision, IE someone using the chidori would have roughly a 70 degree range of vision, because of the tunnel vision so even if the byakugan is effected by the tunnel vision, it wouldn't be that big of a problem because the byakugan user would still have a massive field of vision. 170 goes into 360, 2.11764705882352 times, so a normal human eye's center line vision is 70 degree's the peripheral vision is 100 degree's you take 70 x 2.11764705882352 and you get 148.235294118, meaning the byakugan's center line vision has a 148.235294118 arc, meaning that the byakugan's peripheral vision has a 211.764705882 degree arc. so while a byakugan user might have a loss of 211.764705882 degree's of vision they would still have a higher range of vision than a Sharingan user who simply can mitigate the tunnel vision because of the sharingan's predictive abilities, IE even the sharingan user still has tunnel vision.

so in the end, it wouldn't matter, the byakugan user would still be able to use the chidori
