Why do my eyes change colours?

Question

they'll go from brown one day

then they'll change to hazel

then they'll get a ring of gray around the edge

then they go grey

then green

then blue

WHY!?!?

and is there anything i can do to stop them?

Answer 1

i dont agree with people who say that its the colour of your clothes or the lighting because i can be sitting in one place with the same clothes on and the lighting not changing all dae and my eyes will change from a deep blue to green
