a question for an iridology expert!

ok,I have I can say light brown eyes and what makes them brown is the brown sparks around the pupil,the outside part of the eyes is green,sometimes they get very light and sometimes they darken...my mother has brown eyes and my father baby blue..my older brother was born with pure green eyes...I was wondering if I could do something to get rid of the brown in my eyes even though it sounds unreal...unfortunately...Is there anything I can do?please let me know,any suggestion may be of a great help but honestly though...thank you Tweet
