The eye can be examined with relative ease as to both its function and its structure. A practical evaluation includes the capability to move in the orbit and the response of the pupil to light and lodging.
The function of the eye might be tested in numerous ways. The client might be asked to determine illuminated letter or items of differing sizes on exactly what is called the Snellen chart.
On the other hand, the examination of the structural part of the eye might be made in a number of ways. Stress within the eyeball is measured by a "tonometer." In particular diseases, especially in glaucoma, the tension in the eyeball is increased markedly.
Nevertheless, it needs to be well bore in mind that a client with an eye problem may have other problems also. Frequently other physical conditions are main and affect the eye as a repercussion.
