My eyes are wierd?

i have dark blue pupils (no they are not black) and i have a blue ring around my almost black eyes. my grandpa has the same thing with his pupil. and some of our family has a dark blue ring around their eyes that lighten up with age. does anybody think this is wierd? and i think its hereditary but i dont know anybody else with blue pupils and a blue ring besides my family. oh yeah. one more thing. my eyes are almost black so you can only tell in the sun when they turn brown. what do you think?
