The eye can be examined with relative ease as to both its function and its structure. A practical examination includes the ability to move in the orbit and the reaction of the pupil to light and lodging.
The function of the eye might be evaluated in a number of ways. The patient may be asked to recognize illuminated letter or things of differing sizes on exactly what is referred to as the Snellen chart.
Conversely, the assessment of the structural part of the eye might be made in several ways. Stress within the eyeball is determined by a "tonometer." In specific illness, especially in glaucoma, the tension in the eyeball is increased markedly.
However, it needs to be well remembered that a client with an eye issue may have other problems also. Often other physical conditions are primary and affect the eye as a repercussion. The appearance of the eye can inform the patient and the doctor to troubles in some disruptions of other parts of the body even before other symptoms provide themselves.
Consequently, one's dependence on sight is stressed when one deals with a momentary or possible permanent loss of this crucial sense. For this reason, when corrective measures are sought, certain forms of vision correction such as contact lenses or spectacles are prescribed.
On the other hand, some individuals are troubled with the fact that they have actually some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgical operations were established to motivate decreased usage of contact lenses or glasses. Among which is the now popular LASIK eye surgical treatment.
Generally, LASIK eye surgery is the short-term for "Laser-Assisted In Situ Keratomileusis." Like its tangible equivalent, LASIK eye surgical treatment is another type of vision correction. The only difference is that with this kind of surgery, one's vision is fixed permanently.

Provided all these things, it can be deduced that, in spite of the appeal of the operation, LASIK might not constantly be the ideal eye surgical treatment the method many people see it
Alternatively, the evaluation of the structural part of the eye may be made in a number of ways. It must be well kept in mind that a patient with an eye issue may have other issues.
