Q: I’m 77 years old and I remember my eyes used to be dark brown, but now they’re grey. My doctor said that’s normal. Are my eyes really getting less brown?
A: The colour of your iris usually stays the same throughout your life, but the cornea (the clear surface in front of the iris) can get a little cloudy over time. This is from normal lipid deposits, often within the outside edge of the cornea. If this happens in younger adults, we would wonder about blood lipid levels and that can be investigated of course.
