Eye exam refers more specifically to the collection of tests that are done by an optometrist, ophthalmologist or orthoptist in order to check the vision of a person, as well as his or her focus and recognition of objects. During this process, other tests and exams may be given. It is suggested by health care professionals that people have these exams done routinely as part of their health care routine, especially because many eye diseases are known for be asymptomatic.

Different equipment and techniques are employed for these basic tests, which are usually done through external examination. The very basic exams involve checking of pupil function, extraocular muscle motility and visual acuity. The process is applied by doctors in order to detect blindness, tumors and other potential eye problems. Most insurance providers will offer some portion of coverage for these tests. Prices will range for the test, as well as treatments.

Visual field tests are exams that can be used to detect any dysfunction in peripheral and central vision, which may be the result of medical conditions, such as brain tumors, stroke and glaucoma. This is done clinically by keeping the gaze of patients fixed while presenting various objects in places in their visual field.

Generally, simple equipment is employed during this process, for instance: Amsler grids, tangent screen tests. However, dedicated machinery may be used and if so, the process is then called perimeter. Other names for this kind of exam include Automated perimetry exam, Humphrey field exam, perimetry, Goldmann visual field exam and Tangent screen exam. A test of this sort may be administered by a technician, with aid from a machine or solely by an automated machine.

Numerous eye exams can be carried out. In fact, sometimes these are a requirement. An example of this would be when applying for a certain job in which good eyesight is necessary or before getting a drivers license. There are many doctors and machines that act as vision testers.

Each test has its own purpose and will produce different results. Some may be used solely to check for color blindness and others might be focused on accessing vision close up and far away. There are even tests specifically designed to assess health of the eyes. A doctor consultation is the best way to find out what exams to take, what the results mean, and the steps to take based on those results.
