The eye can be examined with relative ease regarding both its function and its structure. A practical assessment consists of the capability to relocate the orbit and the reaction of the student to light and lodging.
The function of the eye may be tested in several methods. The patient may be asked to identify illuminated letter or items of differing sizes on what is referred to as the Snellen chart.
Alternatively, the evaluation of the structural part of the eye may be made in several ways. Stress within the eyeball is determined by a "tonometer." In specific illness, especially in glaucoma, the tension in the eyeball is increased markedly.
