The eye can be analyzed with relative ease regarding both its function and its structure. A functional examination consists of the capability to move in the orbit and the reaction of the student to light and accommodation.
The function of the eye might be checked in several methods. The patient might be asked to recognize illuminated letter or items of differing sizes on what is referred to as the Snellen chart.
Alternatively, the examination of the structural part of the eye might be made in a number of ways. Tension within the eyeball is determined by a "tonometer." In certain illness, particularly in glaucoma, the stress in the eyeball is increased noticeably.
