The eye can be analyzed with relative ease regarding both its function and its structure. A functional evaluation consists of the ability to relocate the orbit and the reaction of the pupil to light and lodging.
The function of the eye may be checked in several methods. The client might be asked to determine illuminated letter or objects of varying sizes on exactly what is called the Snellen chart.
Alternatively, the examination of the structural part of the eye might be made in several ways. Stress within the eyeball is determined by a "tonometer." In certain illness, especially in glaucoma, the tension in the eyeball is increased markedly.
