I know i've made threads in the past in reference to the byakagan being able to bend and perceive light but I think its not as simple as that.
One thing that people forget is the Byakagan is capable of seeing the internals of their opponents. This may seem like much but when you think about it its the most vital ability one can have in a fight.
Seeing the internals of an opponent and also being skilled enough to use the eyes would allow someone to:
1) See Chakra flow in real time which based on Manga chakra flows at an extremely high pace. Meaning you can see without sensing what type of jutsu someone is going to use and where they are building chakra at.
Example Neji seeing Deidara Bomb
AO seeing Danzo Eye
2) You can see the muscle and muscle fibers around the chakra network to determine what type of attack the person will use. No matter how fast someone is. Chakra and muscle twitching is required which is visible before the person makes their move.
In essence you can say that an individuals body telegraphs their entire arsenal before they can perform it fully.
Keep in mind this is when Byakagan is welded by capable hands. This would also explain why Byakagan users have a harder time detecting Taijutsu as their is no major chakra usage.
Thoughts?
