MODEL RELEASED. Eye examination. Image 15 of 15. Ophthalmologist watching a patient examine how he looks in a pair of frames, using a computer. The computer has a camera on top of the monitor, which takes a picture of the patient. It then stores the images (right-hand side) so that the patient can compare how different frames look on him. An eye examination not only identifies sight deterioration, it can also reveal underlying health problems such as high blood pressure or diabetes. A healthy individual should have an eye test every two years. See M450/267-281 for an eye examination.
