The eye can be analyzed with relative ease as to both its function and its structure. A functional evaluation consists of the ability to relocate the orbit and the response of the pupil to light and lodging.
The function of the eye may be tested in a number of methods. The client may be asked to recognize illuminated letter or objects of varying sizes on what is called the Snellen chart.
Alternatively, the examination of the structural part of the eye may be made in several ways. Tension within the eyeball is measured by a "tonometer." In certain diseases, specifically in glaucoma, the stress in the eyeball is increased markedly.
However, it should be well kept in mind that a patient with an eye problem may have other issues too. Often other physical conditions are main and impact the eye as a effect. The appearance of the eye can alert the doctor and the patient to difficulties in some disturbances of other parts of the body even prior to other symptoms present themselves.

For this reason, advanced surgeries were established to encourage decreased usage of contact lenses or glasses. Among 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 tangible counterpart, LASIK eye surgical treatment is another form of vision correction. The only difference is that with this kind of surgery, one's vision is fixed completely.

The main purpose of this surgery is to develop a threadlike, rounded "flap" in the cornea using a blade known as "microkeratome." In a series of unfolding and laser processing, the cornea is finally reformed, allowing much better the eye to direct more light into the retina.
Appeal vs. Disadvantages

Provided all these things, it can be deduced that, in spite of the popularity of the operation, LASIK may not constantly be the ideal eye surgical treatment the way the majority of individuals see it
Conversely, the examination of the structural part of the eye may be made in numerous methods. It should be well kept in mind that a patient with an eye problem may have other problems. Often other physical conditions are primary and affect the eye as a consequence. The appearance of the eye can notify the client and the doctor to problems in some disturbances of other parts of the body even before other symptoms provide themselves.
