The eye can be analyzed with relative ease regarding both its function and its structure. A practical examination includes the capability to move in the orbit and the response of the student to light and lodging.
The function of the eye may be evaluated in a number of ways. The patient may be asked to identify illuminated letter or objects of varying sizes on what is referred to as the Snellen chart.
On the other hand, the assessment of the structural part of the eye may be made in several methods. Tension within the eyeball is measured by a "tonometer." In specific diseases, especially in glaucoma, the tension in the eyeball is increased considerably.
It needs to be well kept in mind that a client with an eye problem may have other problems. Typically other physical conditions are primary and affect the eye as a effect.
