Not necessarily! An eye freckle is called a nevus. It is a common, colored growth, similar to a freckle on your skin. You can have a nevus in the front of your eye, around the iris, or under the retina at the back of the eye. A nevus under the retina is called a choroidal nevus. An eye nevus is usually harmless. However, it needs to be monitored because, like a skin freckle, it could possibly develop into cancer of the eye.
