The function of the eye may be evaluated in numerous methods. The client might be asked to recognize illuminated letter or objects of differing sizes on exactly what is understood as the Snellen chart.
Conversely, the examination of the structural part of the eye might be made in numerous methods. Stress within the eyeball is measured by a "tonometer." In particular diseases, especially in glaucoma, the tension in the eyeball is increased markedly.
However, it should be well bore in mind that a patient with an eye problem may have other issues also. Typically other physical conditions are primary and impact the eye as a repercussion. The look of the eye can inform the patient and the doctor to difficulties in some disruptions of other parts of the body even prior to other symptoms provide themselves.

On the other hand, some individuals are troubled with that they have actually some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgeries were developed to encourage reduced usage of contact lenses or glasses. Among which is the now popular LASIK eye surgery.
