The eye can be analyzed with relative ease regarding both its function and its structure. A practical evaluation includes the ability to relocate the orbit and the response of the pupil 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.
