The function of the eye may be checked in a number of methods. The client may be asked to recognize illuminated letter or items of varying sizes on exactly what is referred to as the Snellen chart.
On the other hand, the assessment of the structural part of the eye might be made in a number of methods. Stress within the eyeball is determined by a "tonometer." In certain illness, especially in glaucoma, the tension in the eyeball is increased considerably.
Nevertheless, it should be well kept in mind that a client with an eye issue might have other issues too. Frequently other physical conditions are main and impact the eye as a consequence.
