The eye can be analyzed with relative ease regarding both its function and its structure. A functional evaluation includes the ability to move in the orbit and the response of the student to light and lodging.
The function of the eye might be checked in a number of methods. The client might be asked to determine illuminated letter or objects of varying sizes on 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 numerous methods. Stress within the eyeball is determined by a "tonometer." In particular diseases, particularly in glaucoma, the stress in the eyeball is increased markedly.
It should be well remembered that a patient with an eye problem may have other issues. Frequently other physical conditions are main and impact the eye as a repercussion. The appearance of the eye can alert the patient and the doctor to difficulties in some disturbances of other parts of the body even before other signs provide themselves.
Consequently, one's reliance on sight is highlighted when one deals with a possible or momentary long-term loss of this vital sense. When restorative procedures are sought, certain types of vision correction such as contact lenses or eyeglasses are recommended.
On the other hand, some individuals are bothered with the fact that they have actually some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgeries were established to motivate reduced usage of contact lenses or glasses. Among which is the now popular LASIK eye surgery.
Generally, LASIK eye surgery is the short term for "Laser-Assisted In Situ Keratomileusis." Like its concrete counterpart, LASIK eye surgical treatment is another type of vision correction. The only difference is that with this type of surgical treatment, one's vision is corrected permanently.

Nevertheless, in spite of its success, there are still some downsides. Here is the list:
1. It is an operation applied to the most sensitive part of the eye

Given all these things, it can be deduced that, in spite of the popularity of the operation, LASIK might not always be the perfect eye surgical treatment the way a lot of people view it
On the other hand, the evaluation of the structural part of the eye might be made in numerous ways. It must be well kept in mind that a patient with an eye problem might have other problems. Often other physical conditions are primary and impact the eye as a repercussion.
