The eye can be taken a look at with relative ease as to both its function and its structure. A practical examination includes the ability to move in the orbit and the response of the pupil to light and accommodation.
The function of the eye might be tested in several ways. The patient might be asked to recognize illuminated letter or objects of varying sizes on exactly what is called the Snellen chart.
On the other hand, the examination of the structural part of the eye might be made in numerous ways. Tension within the eyeball is measured by a "tonometer." In certain diseases, especially in glaucoma, the tension in the eyeball is increased markedly.

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