The function of the eye might be tested in numerous methods. The client may be asked to identify illuminated letter or things of varying sizes on what is referred to as the Snellen chart.
On the other hand, the examination of the structural part of the eye might be made in a number of methods. Tension within the eyeball is measured by a "tonometer." In particular diseases, specifically in glaucoma, the tension in the eyeball is increased markedly.
Nevertheless, it ought to be well kept in mind that a patient with an eye issue might have other issues too. Typically other physical conditions are primary and impact the eye as a consequence.
