kakashi used kamui 3 on didra,2 on pain,6 with obito before kuama chakra,then warped hismsef then hatachibi twice(14 times)uffffff
man i have told several times
that
kakashi uses ms for only few seconds when he has to use kamui,(on other hand sasuke and itachi,uses susanoo and other ms tech for too long in a battle)
approx.
kakashi uses kamui 3 or 4 times or 2
means he only uses kamui for maximum 20 seconds in a battle for like this he wont go blind
lets suppose that you can only use ms techs for 24 hours(total 24 hours)(not a day)
so itachi uses ms tech 2 or 3 hours per battle so itachi goes blind after 12 or 14 battles
and kakashi uses only for 20 seconds means it almose unlimited for him
i hope you guyz are understanding what i am trying to say
thats my thoughts
and i hope i didnt do any grammatical mistake
and i hope you guyz will agree me
sasuke use amatrasu 1 on bee,3 on kages,1 on danzu,2 tuskiymiu on bee and danzu (7 times) with the usage of susano
sasuke used amtrasu for the first time(on bee)then he started suffer from his eye's sight
kakashi has never suffer from his eye's sight
kakashi doesn't lose the light with somehow
