The eye can be taken a look at with relative ease as to both its function and its structure. A functional assessment consists of the ability to move in the orbit and the response of the pupil to light and lodging.
The function of the eye may be checked in a number of ways. The client may be asked to determine illuminated letter or objects of differing sizes on exactly what is called the Snellen chart.
Conversely, the assessment of the structural part of the eye may be made in numerous ways. Stress within the eyeball is measured by a "tonometer." In specific illness, particularly in glaucoma, the stress in the eyeball is increased noticeably.

For this factor, advanced surgical operations were established to motivate reduced utilization of contact lenses or glasses. One of which is the now popular LASIK eye surgical treatment.
