#3 High Cholesterol 

Not only can high blood pressure be found during a comprehensive eye exam, but high cholesterol can also be discovered.

People with high cholesterol sometimes have either a blue or yellow ring located around their cornea. There might also be deposits left behind in the blood vessels that are in a person’s retina that can indicate high cholesterol levels.

In some instances, an optometrist may even be able to tell if a person is on the brink of having a stroke caused by high cholesterol by looking at their eyes.
