The eye can be analyzed with relative ease as to both its function and its structure. A practical assessment includes the ability 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 methods. The client may be asked to identify illuminated letter or objects of differing sizes on exactly what is referred to as the Snellen chart.
On the other hand, the evaluation of the structural part of the eye may be made in a number of methods. Tension within the eyeball is measured by a "tonometer." In particular illness, particularly in glaucoma, the stress in the eyeball is increased markedly.
It ought to be well kept in mind that a patient with an eye issue may have other issues. Often other physical conditions are primary and affect the eye as a repercussion.
