The function of the eye may be tested in a number of ways. The client may be asked to determine illuminated letter or objects of differing sizes on exactly what is referred to as the Snellen chart.
On the other hand, the examination 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, particularly 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 may have other issues also. Often other physical conditions are primary and impact the eye as a effect.

On the other hand, some people are bothered with that they have actually some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgical operations were developed to motivate decreased utilization of contact lenses or glasses. One of which is the now popular LASIK eye surgical treatment.
