The eye can be analyzed with relative ease regarding both its function and its structure. A practical examination consists of the capability to move in the orbit and the response of the pupil to light and lodging.
The function of the eye may be tested in numerous ways. The client may be asked to identify illuminated letter or objects of differing sizes on what is called the Snellen chart.
Conversely, the assessment of the structural part of the eye might be made in numerous methods. Stress within the eyeball is determined by a "tonometer." In particular illness, especially in glaucoma, the stress in the eyeball is increased markedly.
