The eye can be analyzed with relative ease regarding both its function and its structure. A functional examination includes 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 might be asked to recognize illuminated letter or things of differing sizes on what is referred to as the Snellen chart.

For this factor, advanced surgeries were established to motivate reduced utilization of contact lenses or glasses. One of which is the now popular LASIK eye surgical treatment.
Basically, LASIK eye surgery is the short term for "Laser-Assisted In Situ Keratomileusis." Like its concrete counterpart, LASIK eye surgical treatment is another form of vision correction. The only difference is that with this kind of surgical treatment, one's vision is remedied completely.
