The eye can be examined with relative ease as to both its function and its structure. A practical evaluation includes the ability to move in the orbit and the reaction of the pupil to light and accommodation.
The function of the eye may be checked in a number of ways. The client may be asked to identify illuminated letter or things of differing sizes on exactly what is understood as the Snellen chart.
Alternatively, the examination of the structural part of the eye may be made in several methods. Tension within the eyeball is determined by a "tonometer." In particular illness, especially in glaucoma, the stress in the eyeball is increased noticeably.
