The eye can be taken a look at with relative ease as to both its function and its structure. A practical evaluation includes the capability to move in the orbit and the response of the pupil to light and accommodation.
The function of the eye may be checked in numerous ways. The client may be asked to recognize illuminated letter or items of differing sizes on exactly what is known as the Snellen chart.
On the other hand, the evaluation of the structural part of the eye might be made in a number of ways. Stress within the eyeball is determined by a "tonometer." In particular diseases, especially in glaucoma, the tension in the eyeball is increased markedly.
