The eye can be taken a look at with relative ease regarding both its function and its structure. A functional examination consists of the capability to move in the orbit and the reaction of the student to light and lodging.
The function of the eye may be checked in several ways. The client might be asked to determine illuminated letter or things of varying sizes on what is referred to as the Snellen chart.
Conversely, the examination of the structural part of the eye might be made in several methods. Stress within the eyeball is determined by a "tonometer." In certain diseases, especially in glaucoma, the stress in the eyeball is increased markedly.

For this factor, advanced surgeries were developed to motivate reduced usage of contact lenses or glasses. Among which is the now popular LASIK eye surgery.
Essentially, LASIK eye surgery is the short-term for "Laser-Assisted In Situ Keratomileusis." Like its concrete equivalent, LASIK eye surgical treatment is another kind of vision correction. The only distinction is that with this kind of surgery, one's vision is fixed permanently.
