The eye can be taken a look at with relative ease regarding both its function and its structure. A functional assessment consists of the capability to relocate the orbit and the response of the pupil to light and accommodation.
The function of the eye may be evaluated in several ways. The patient might be asked to recognize illuminated letter or objects of varying sizes on what is understood as the Snellen chart.
On the other hand, the examination of the structural part of the eye may be made in a number of methods. Tension within the eyeball is measured by a "tonometer." In specific illness, especially in glaucoma, the tension in the eyeball is increased considerably.
However, it should be well kept in mind that a client with an eye issue might have other issues also. Often other physical conditions are primary and impact the eye as a effect. The look of the eye can alert the patient and the doctor to problems in some disturbances of other parts of the body even before other signs present themselves.

On the other hand, some individuals are bothered with that they have actually some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgeries were established to encourage reduced utilization of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
