The eye can be examined with relative ease as to both its function and its structure. A practical assessment includes the capability to relocate the orbit and the response of the pupil to light and lodging.
The function of the eye may be evaluated in several methods. The client may be asked to identify illuminated letter or objects of differing sizes on exactly what is referred to as the Snellen chart.
Alternatively, the evaluation of the structural part of the eye might be made in a number of ways. Tension within the eyeball is measured by a "tonometer." In particular diseases, specifically in glaucoma, the tension in the eyeball is increased significantly.
