Corneal arcus can affect people of all ages and is often associated with high cholesterol levels in the body (via Verywell Health). In people 60 years and older, the arc itself is made of fat deposits around the eye, and for many, this is a normal part of aging, requiring no treatment. In fact, the American Academy of Ophthalmology states that most people will eventually develop the condition.
But in younger people, a gray ring is a sign of high cholesterol that may only worsen with time. As noted by WebMD, corneal arcus before your senior years could indicate a significant risk of heart disease and cholesterol problems.
For young and middle-aged people noticing a grayish ring around their cornea, it's best to see an eye doctor for a thorough checkup. Not only will it ensure your eyes are okay, but it can provide some valuable insight into your heart health too.
