Could my ambiopia be caused by me having 2 differenct color eyes? Lt is brown, rt is blue on top brown on bottom. Rt one is my problem eye.

Not related. Amblyopia, usually defined as poor vision in one eye without anatomical abnormality, would not likely be related to differences in eye color. The changes you describe could be from an iris nevus (like a "birthmark") or some other uncommon eye problems. Have a thorough eye examination by an ophthalmologist to sort it out.
