Almost a year ago I had blue eyes so light they were almost white. Few months ago I noticed a bit of a change in them, now I have a red-ish circle around my black dot(the black dot in the center of the eye, forgot how it's called). Now I am wondering is this natural, or some kind of sickness, and if it can or cannot be cured. And I'd love to have my old colour back if possible. I'd put up here a picture, but I don't think this forum allows it.
Well, I've always wanted blue eyes (or green) and mine are so dark, I don't think I'd notice a change like you mentioned, if I had it! So, this could be good in that you notice a problem before it becomes worse. Did you see an eye specialist? I think you need an ophthalmologist.
Your iris is the light blue part, the pupil is the dark dot and I don't know what the red ring is but if it's new, it probably shouldn't be there. Since you don't mention vision trouble, my guess is that it's an infection and easily cured...then back to your white-blue eyes!
Good Luck!
Do you wear contact lenses? If you do this could be simple inflammation from a badly fitted or faulty lens. I'm guessing you dont wear lenses as you havent mentioned them
This red ring could indicate an inflammation on the inside of your eye. Are you fair skinned or dark? Are your eyes sensitive to light? Do you wear sunglasses in bright sun? You need to see an ophthalmologist who can see the inside of your eye to make a diagnosis. A red ring is not normal and your eyes are precious. Dont neglect them.
When your Iris changes colour, it is called Heterochromia &, as everyone has said, your eyes are precious, you need to see an Ophthalmologist, that is a doctor who specialises in eyes & is found in a hospital.
An Optometrist, sometimes called an Optician, is someone who is not medically qualified but can examine your eyes & refer you to an Ophthalmologist in a hospital.
This leaflet explains a little about Heterochromia
