The eye can be examined with relative ease regarding both its function and its structure. A practical assessment includes the capability to relocate the orbit and the reaction of the student to light and accommodation.
The function of the eye may be checked in numerous ways. The client may be asked to recognize illuminated letter or objects of differing sizes on what is referred to as the Snellen chart.
