The eye can be taken a look at with relative ease regarding both its function and its structure. A practical assessment includes the ability to move in the orbit and the response of the pupil to light and accommodation.
The function of the eye may be tested in a number of methods. The patient might be asked to recognize illuminated letter or items of differing sizes on what is called the Snellen chart.
Conversely, the assessment of the structural part of the eye may be made in numerous methods. Tension within the eyeball is measured by a "tonometer." In specific diseases, especially in glaucoma, the stress in the eyeball is increased markedly.
However, it should be well kept in mind that a patient with an eye issue may have other issues too. Often other physical conditions are primary and impact the eye as a effect.

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