The eye can be examined with relative ease as to both its function and its structure. A functional assessment includes the ability to relocate the orbit and the response of the student to light and accommodation.
The function of the eye might be checked in several methods. The client might be asked to identify illuminated letter or objects of differing sizes on what is understood as the Snellen chart.
