The eye can be taken a look at with relative ease as to both its function and its structure. A functional examination consists of the capability to move in the orbit and the reaction of the pupil to light and accommodation.
The function of the eye might be checked in numerous ways. The patient may be asked to recognize illuminated letter or things of differing sizes on exactly what is understood as the Snellen chart.
Conversely, the examination of the structural part of the eye might be made in several ways. Stress within the eyeball is measured by a "tonometer." In certain illness, particularly in glaucoma, the tension in the eyeball is increased significantly.
It needs to be well remembered that a patient with an eye issue may have other issues. Typically other physical conditions are main and impact the eye as a effect.

For this reason, advanced surgical operations were developed to encourage decreased utilization of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
