The eye can be examined with relative ease as to both its function and its structure. A functional examination consists of the ability to move in the orbit and the response of the pupil to light and accommodation.
The function of the eye might be tested in several methods. The patient may be asked to determine illuminated letter or items of varying sizes on exactly what is referred to as the Snellen chart.
On the other hand, the examination of the structural part of the eye might be made in numerous ways. Stress within the eyeball is measured by a "tonometer." In particular illness, particularly in glaucoma, the tension in the eyeball is increased considerably.
It must be well kept in mind that a client with an eye problem might have other problems. Often other physical conditions are primary and affect the eye as a consequence.

For this reason, advanced surgeries were developed to motivate reduced usage of contact lenses or glasses. Among which is the now popular LASIK eye surgery.
