The eye can be analyzed with relative ease as to both its function and its structure. A functional evaluation includes the ability 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 differing sizes on what is called the Snellen chart.
On the other hand, the assessment of the structural part of the eye may be made in numerous ways. Tension within the eyeball is determined by a "tonometer." In particular illness, especially in glaucoma, the stress in the eyeball is increased considerably.
Nevertheless, it should be well bore in mind that a patient with an eye problem might have other issues too. Often other physical conditions are main and impact the eye as a effect. The look of the eye can inform the physician and the client to difficulties in some disturbances of other parts of the body even before other symptoms provide themselves.
As a result, one's dependence on sight is emphasized when one faces a possible or short-lived long-term loss of this vital sense. Thus, when corrective steps are sought, certain types of vision correction such as contact lenses or eyeglasses are prescribed.
On the other hand, some people are bothered with the reality that they have actually some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgical operations were established to encourage reduced usage of contact lenses or glasses. One of which is the now popular LASIK eye surgical treatment.
Basically, LASIK eye surgical treatment is the short term for "Laser-Assisted In Situ Keratomileusis." Like its concrete counterpart, LASIK eye surgery is another form of vision correction. The only distinction is that with this type of surgery, one's vision is corrected permanently.
