Eye and Vision Care
I have partial heterochromia (hypochromatic) on my left eye, and although the spot has changed shape while I grew up, it is recently becoming noticably bigger in size. I have hazel eyes and the spot is grey. Is there anything I might be doing or environmental factors that may be causing it to grow?
Changes in iris coloration can occur normally over time. However, any spot that becomes noticeably bigger should be looked at by an eye doctor to rule out iris atrophy or an iris tumor.
In answer to your question, I am not aware of any environmental factors that would cause a hypo-pigmented area of the iris to get larger.
