The function of the eye may be checked in numerous ways. The client may be asked to determine illuminated letter or things 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 several methods. Stress within the eyeball is measured by a "tonometer." In particular illness, specifically in glaucoma, the stress in the eyeball is increased markedly.
It should be well remembered that a patient with an eye issue may have other issues. Typically other physical conditions are primary and affect the eye as a repercussion.
