The eye can be analyzed with relative ease regarding both its function and its structure. A functional assessment includes the ability to move in the orbit and the reaction of the pupil to light and accommodation.
The function of the eye might be evaluated in a number of methods. The client may be asked to determine illuminated letter or objects of differing sizes on exactly what is called the Snellen chart.
Alternatively, the assessment of the structural part of the eye may be made in numerous ways. Stress within the eyeball is measured by a "tonometer." In particular diseases, especially in glaucoma, the tension in the eyeball is increased markedly.
