Arcus: Arcus refers to a bluish or grayish-white ring seen around the edge of the cornea, in front of the iris color. It occurs as lipids are deposited in that area, normally seen in older people. In a young person, it can be a sign of high cholesterol.

Corneal arcus: This is a normal deposit of lipid at the edge of the cornea, the clear window at the front of the eye. These have been found to be benign, and not in fact related to your blood lipid composition. They do not affect the vision or the health of the eye.
