The function of the eye may be checked in a number of ways. The client may be asked to recognize illuminated letter or items of differing sizes on what is understood as the Snellen chart.
Alternatively, the evaluation of the structural part of the eye might be made in several methods. Tension within the eyeball is determined by a "tonometer." In certain illness, specifically in glaucoma, the tension in the eyeball is increased markedly.
