can a doctor know you have eye disease/illness just by looking at your eye in a vision checkup?

Yes: Multiple general medical conditions can be detected in the eye-specifically the retina, the tissue that line the back of the eye and "senses" the light. Common conditions such as diabetes, high blood pressure and high cholesterol can be seen. Anemia and certain types of infections can also be seen. Often their severity in the eye is an indication of the disease's severity for general health.
