Arcus: You probably have cholesterol deposits in the peripheral cornea causing the iris to appear gray. See an eye doctor for confirmation and get your cholesterol level checked.
Dr. Richard Bensinger

Corneal arcus: This is a deposit of lipid next to the outer part of the colored part of the eye (the edge of the cornea). It is benign, does not affect vision and is very common.
