The eye can be analyzed with relative ease as to both its function and its structure. A practical evaluation includes the capability to relocate the orbit and the reaction of the pupil to light and lodging.
The function of the eye might be checked in a number of methods. The client may be asked to determine illuminated letter or objects of differing sizes on what is known as the Snellen chart.
Alternatively, the evaluation of the structural part of the eye may be made in a number of methods. Stress within the eyeball is measured by a "tonometer." In specific illness, especially in glaucoma, the stress in the eyeball is increased considerably.
Nevertheless, it must be well bore in mind that a client with an eye problem may have other problems also. Often other physical conditions are primary and affect the eye as a effect. The appearance of the eye can alert the doctor and the patient to troubles in some disruptions of other parts of the body even prior to other signs present themselves.

For this factor, advanced surgical operations were developed to encourage reduced utilization of contact lenses or glasses. Among which is the now popular LASIK eye surgery.
Generally, LASIK eye surgical treatment 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 primary purpose of this surgery is to develop a threadlike, rounded "flap" in the cornea using a blade called "microkeratome." In a series of unfolding and laser processing, the cornea is finally reformed, enabling much better the eye to direct more light into the retina.
