This is what I have always thought. That one full eye to differ, fully, the other eye; is different than having a random, discolouration, or uncommon colouring of the eyes. But, mine is very prominent. It bothers me a lot. I don't know what to tell people. Other than - "These are my eyes...(?)"
Seeing though the Google photos of others... Has been helpful... I have met one other person in the city i presently call hoe with the exact same eyes as myself. That person - when I met him... He would not even acknowledge it... But, that was the first person ever I have seen with this exact ... blue / half brown , half blue.
