The eye can be examined with relative ease regarding both its function and its structure. A practical assessment consists of the capability to move in the orbit and the reaction of the pupil to light and lodging.
The function of the eye might be tested in several ways. The patient might be asked to recognize illuminated letter or objects of varying sizes on what is called the Snellen chart.
Conversely, the evaluation of the structural part of the eye might be made in a number of methods. Tension within the eyeball is measured by a "tonometer." In particular diseases, especially in glaucoma, the tension in the eyeball is increased significantly.
It must be well kept in mind that a client with an eye issue might have other issues. Typically other physical conditions are primary and impact the eye as a repercussion.

On the other hand, some people are troubled with the fact that they have some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgeries were developed to motivate decreased usage of contact lenses or glasses. Among which is the now popular LASIK eye surgical treatment.
