The eye can be examined with relative ease as to both its function and its structure. A practical assessment includes the ability to relocate the orbit and the response of the pupil to light and accommodation.
The function of the eye might be checked in a number of methods. The patient might be asked to identify illuminated letter or things of varying sizes on exactly what is called the Snellen chart.
Conversely, the evaluation 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 certain illness, particularly in glaucoma, the stress in the eyeball is increased considerably.
However, it should be well bore in mind that a patient with an eye issue might have other problems as well. Frequently other physical conditions are primary and impact the eye as a effect. The look of the eye can signal the patient and the doctor to difficulties in some disruptions of other parts of the body even before other symptoms provide themselves.

On the other hand, some individuals are bothered with that they have some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgical operations were established to encourage decreased 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 surgery is another type of vision correction. The only distinction is that with this type of surgical treatment, one's vision is corrected completely.
With LASIK eye surgery, the refractive mistakes in the cornea are permanently transformed. This can be done using an "excimer laser."
The main function of this surgery is to produce a threadlike, rounded "flap" in the cornea using a blade referred to as "microkeratome." In a series of unfolding and laser processing, the cornea is finally reformed, allowing better the eye to direct more light into the retina.
