The eye can be examined with relative ease as to both its function and its structure. A practical examination consists of the ability to move in the orbit and the reaction of the student to light and lodging.
The function of the eye may be evaluated in several methods. The patient might be asked to recognize illuminated letter or things of differing sizes on what is known as the Snellen chart.
Alternatively, the examination of the structural part of the eye may be made in a number of ways. Stress within the eyeball is determined by a "tonometer." In certain illness, particularly in glaucoma, the stress in the eyeball is increased markedly.
