The eye can be examined with relative ease regarding both its function and its structure. A practical examination consists of the ability to relocate the orbit and the response of the student to light and lodging.
The function of the eye might be tested in several ways. The patient may be asked to recognize illuminated letter or things of differing sizes on exactly what is called the Snellen chart.
Alternatively, the evaluation of the structural part of the eye may be made in numerous methods. Tension within the eyeball is determined by a "tonometer." In certain illness, particularly in glaucoma, the tension in the eyeball is increased markedly.
