The eye can be analyzed with relative ease as to both its function and its structure. A practical evaluation consists of the ability to relocate the orbit and the reaction of the pupil to light and accommodation.
The function of the eye might be tested in several methods. The client may be asked to recognize illuminated letter or items of differing sizes on what is understood as the Snellen chart.
