The function of the eye may be evaluated in numerous methods. The patient may be asked to identify illuminated letter or things of varying sizes on exactly what is referred to as the Snellen chart.
Alternatively, the examination of the structural part of the eye might be made in a number of methods. Stress within the eyeball is measured by a "tonometer." In specific illness, specifically in glaucoma, the stress in the eyeball is increased significantly.
However, it must be well kept in mind that a patient with an eye issue may have other problems also. Often other physical conditions are primary and affect the eye as a consequence.

On the other hand, some people are bothered with the truth that they have some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgeries were developed to motivate reduced utilization 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 concrete counterpart, LASIK eye surgical treatment is another kind of vision correction. The only distinction is that with this type of surgery, one's vision is corrected completely.
