The eye can be examined with relative ease as to both its function and its structure. A functional evaluation consists of the capability to relocate the orbit and the reaction of the student to light and lodging.
The function of the eye may be tested in a number of methods. The client may be asked to determine illuminated letter or objects of varying sizes on what is called the Snellen chart.
