Do you see the white arcs on the superior and inferior portion of this person's cornea? This is called "arcus," and is very common over age 50. However, under age 50, it can indicate high cholesterol. Often, arcus is not visible with the naked eye, and is usually only visible with a biomicroscope that an eye doctor would use during a routine exam. A lot of underlying systemic problems (including high cholesterol, high blood pressure, and Diabetes) can actually first be discovered by way of a proper eye exam. Don't neglect the importance of your yearly eye exams!
