In middle-aged or older adults, a grey, white or blue ring around the iris is most likely an "arcus senilis." This is a layer of lipids -- fatty tissue -- deposited at the meeting point of the iris and sclera. This is a normal part of aging in many people, and nothing to worry about. In younger adults and children, the onset of this type of ring can be associated with high cholesterol or other systemic health issues. If you are younger and are seeing this condition, you should be evaluated by an ophthalmologist, notes Robert Melendez, MD, of the American Academy of Ophthalmology.
