The function of the eye might be tested in numerous methods. The client may be asked to determine illuminated letter or objects of differing sizes on exactly what is called the Snellen chart.
On the other hand, the examination of the structural part of the eye may be made in several methods. Stress within the eyeball is determined by a "tonometer." In specific diseases, especially in glaucoma, the tension in the eyeball is increased significantly.
