Iris
A white or gray ring around the colored part of the eye is called corneal arcus. It can happen naturally with aging, especially after 60. But if it appears in a younger person, it may be a reason to check cholesterol. NHS Wales notes that corneal arcus can occur naturally in older adults, but it can also be a reason to have cholesterol measured.
This sign does not confirm high cholesterol by itself, but it is worth discussing with a doctor or eye specialist.
