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 response of the student to light and accommodation.
The function of the eye may be tested in several methods. The patient might be asked to determine illuminated letter or items of differing 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 a number of methods. Tension within the eyeball is determined by a "tonometer." In specific illness, specifically in glaucoma, the tension in the eyeball is increased significantly.
However, it needs to be well kept in mind that a client with an eye problem may have other issues as well. Typically other physical conditions are primary and affect the eye as a effect.

For this factor, advanced surgical operations were established to motivate decreased usage of contact lenses or glasses. One of which is the now popular LASIK eye surgical treatment.
