Is the vision affected?
Besides colour change is there any other problem in eyes?
Do you mean to say that the colour of iris has changed from blue to brown?
There is no change either way in the vision. The iris that is usually blue, has a brown coloration on the outside, on the rim per se. Let's say the iris is blue with a brown shading on the outside. It is in both eyes. Patient feels lethargic.
Patient also has a history of dark circles under the eyes that is darker with sleep deprivation.
Is he having a mild heart attack?
Hello dark circles may be related to allergies and possibly sleep deprivation. Brown discoloration does not seem to be a cause for concern. It can happen with age. The concerned person can see an ophthalmologist for confirmation. Thanks and best wishes.
