Yes, add rings to the list of things that indicate aging such as gray hair, larger waistlines and reading glasses. It's called an "arcus" of the cornea. It sometimes is associated with high blood cholesterol (its actually clolesterol deposited at the level of the end of Bowman's membrane of the cornea). It is not any sort of a visual problem and is not deposited in the part of the cornea you actually see through.
If you have not had a lipid profile of your blood drawn after an 8-14 hour fast, you should do so.

I went to see an optician to change my glasses. After examination of the eye he said to me there is a bluish ring around your pupil. Its an indication of cholestrol. Go and see a doctor.
Please could you throw light on this as I am scared.
Thank you
