The function of the eye might be tested in a number of ways. The client may be asked to determine illuminated letter or things of differing sizes on what is called the Snellen chart.
Conversely, the assessment of the structural part of the eye might be made in a number of ways. Stress within the eyeball is determined by a "tonometer." In certain illness, especially in glaucoma, the stress in the eyeball is increased considerably.
