The eye can be analyzed with relative ease regarding both its function and its structure. A functional assessment consists of the capability to move in the orbit and the reaction of the student to light and accommodation.
The function of the eye may be evaluated in numerous methods. The client may be asked to identify illuminated letter or things of varying sizes on exactly what is understood as the Snellen chart.
On the other hand, the examination of the structural part of the eye might be made in a number of ways. Stress within the eyeball is measured by a "tonometer." In particular diseases, specifically in glaucoma, the tension in the eyeball is increased markedly.
However, it needs to be well bore in mind that a patient with an eye problem might have other issues as well. Typically other physical conditions are primary and impact the eye as a consequence. The appearance of the eye can alert the physician and the client to difficulties in some disruptions of other parts of the body even before other symptoms present themselves.
Consequently, one's reliance on sight is emphasized when one faces a possible or short-lived long-term loss of this vital sense. When corrective procedures are sought, specific kinds of vision correction such as contact lenses or spectacles are prescribed.
On the other hand, some individuals are troubled with the reality that they have some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgeries were established to motivate decreased usage of contact lenses or glasses. One of which is the now popular LASIK eye surgical treatment.
Generally, LASIK eye surgery is the short-term for "Laser-Assisted In Situ Keratomileusis." Like its concrete counterpart, LASIK eye surgical treatment is another kind of vision correction. The only difference is that with this kind of surgery, one's vision is corrected completely.

Offered all these things, it can be deduced that, in spite of the popularity of the operation, LASIK might not always be the ideal eye surgical treatment the method many people view it
Conversely, the evaluation of the structural part of the eye might be made in several methods. It must be well kept in mind that a patient with an eye issue may have other problems.
