The function of the eye may be evaluated in a number of ways. The client may be asked to recognize illuminated letter or objects of differing sizes on what is known as the Snellen chart.
Conversely, the evaluation of the structural part of the eye may be made in a number of methods. Stress within the eyeball is measured by a "tonometer." In specific illness, especially in glaucoma, the stress in the eyeball is increased markedly.
However, it needs to be well kept in mind that a patient with an eye problem may have other problems also. Typically other physical conditions are main and impact the eye as a consequence.
