The function of the eye might be evaluated in several methods. The patient might be asked to recognize illuminated letter or items of differing sizes on what is called the Snellen chart.
On the other hand, the assessment of the structural part of the eye may be made in a number of methods. Tension within the eyeball is determined by a "tonometer." In certain illness, specifically in glaucoma, the stress in the eyeball is increased considerably.
