The eye can be examined with relative ease regarding both its function and its structure. A practical examination includes the capability to relocate the orbit and the response of the pupil to light and lodging.
The function of the eye may be evaluated in numerous methods. The patient might be asked to recognize illuminated letter or objects of differing sizes on what is referred to as the Snellen chart.
